Cold and Snow This Weekend

10:35 am 03/10/17

Good Friday Morning everyone! Well, the weekend is just about here and it comes with cold and snow. Yes, snow is in the forecast. First off, I want to go ahead and point out that there is a FREEZE warning in place for everybody in Kentucky. That goes through tonight and early Saturday morning.  That means that any tender vegetation that’s growing ahead of schedule is susceptible to damage.

Freeze Warning

Now.. What should we expect within the next 24 hours…

NAM-Weekend-Snow

Latest model runs suggest that places south will get the biggest impact from the snow. The NAM model run hints at heavy wet snow moving through south western Kentucky and into Tennessee. Here in our area, we can generally expect just some light snow showers that will just put down some minor accumulations.  Overall, timing of snow is through the day on Saturday, I’m not anticipating anything significant.

 

I made just a short graphic on what the expectations of snow should be this weekend.

My confidence on even seeing an inch of snow is low.

What to Expect this weekend

The next thing I’m watching is a system that will push through Monday night into Tuesday morning, that seems to have a better chance on seeing accumulating snows. I’ll keep you posted!

*ALSO: Daylight Savings Time Begins March 12TH AT 2AM. Be sure to move clocks AHEAD 1 hour Saturday night!

 

Try to stay warm this weekend!

Snow Update

3:54PM January 5, 2017

The snow has arrived and it continues to snow lightly. Radar is showing the snow filtering in from the west. The darker contours indicate periods of heavier snow, that’s something to watch as the evening wears on. A general 1″-3″ is expected.

Today there were already school closings and for some that went, early dismissals.

With that being said. Lets see how the roads are:

Tracking Snow Chances

11:30AM  January 4,2017

Happy New Year! Winter has arrived and despite Kentucky weather’s Spring-like escapades, we’re always reminded that Winter is still upon us. For the last two days its been dreary and in the 60s. Today, bare cold and frigid weather is filtering into the region. But lets be hopeful, if you feel like you’re missing out on the snow this season, there’s a good chance we get our first accumulating snowfall later this week, in fact, soon!

 

Tomorrow, I’m tracking a snowmaker that will usher through in waves. The track and chances of this snow system has been consistent over the past couple of days, it’s not going to be a shutdown snow, but it is just enough snow to be noticed. As you can see from the NAM run, the snow moves in as early as Thursday morning. However, keep in mind that the snow must tackle some of the dry air we have place now. So, it’s likely we’ll start off with just a couple of flakes falling from the sky. Don’t anticipate an immediate “snow down” once the first flakes arrive. I’ll say around 10am-the afternoon and evening, we’ll see some moderate and even heavier bands of snow that could put down a couple of inches in some spots.

In terms of accumulation, NAM is putting the I-64 corridor around the 1”-3” for accumulating snow. *NOTE This goes from Thursday through Friday morning.

Here’s my initial thoughts on the expected snowfall…

So kids, Snow day tomorrow? Not likely, I think there’s a better chance for school closings Friday.

Tracking Pre-Dawn Storms

10:45pm 06/22/16 Good evening! It’s been a while since I’ve updated this blog, but don’t worry, i have not forgotten. Today was an important day for me because I turned 19. Also, I want to just say thanks to all of my friends and family that sent me the best wishes.

Now to get to the real stuff…

There is a threat for severe weather late tonight and super early tomorrow morning, primarily within the morning hours between 4-7 am. Which means that if you enjoy sleeping, well, you’re just going to have sleeping troubles. The HRRR suggests a heavy line of storms tracking from north to south. There’s no doubt that damaging winds will be a great likelihood.

HRRR-storms-run

Your Threat Index shows the greatest threats would be lightning, damaging wind, and hail. The lowest threat is the Tornado threat, However, that’s something to continue to watch as models are hinting that there could be enough spin energy to produce isolated tornadoes.

I’ll keep you posted!

Thursday School Watch Meter

8:15pm 03/2

I’m going to be short and to the point since I have mid-terms this week. Just when you think we are done with snow, it seems that it always makes it’s special and maybe “surprising” appearances, I know this morning’s flurries and chilly conditions reminds us that winter is still here.

Tomorrow, I’m talking possible rain and mixing, something that is sort of catching my attention.

Here’s the timing 11pm-1am is when I suspect rain and snow to arrive, and it will continue through Thursday afternoon. Temps today have hovered around the mid to upper 30s and it might not take long for pavement temps to reach the freezing mark which is why I think it’s possible for some accumulating snow tomorrow.

HiResNam

HiResNam 4km, WxBell

 

 

The WxBell HiResNam is showing a system pivoting across the west and will swing rain and snow from the southwest to northern zones. Keep in mind, temperatures will be critical on who gets what. With that being said, I’m not saying this is going to be a MAJOR issue, nor am I saying it’s not going to have any impact. It’s something the be aware of, especially for school systems when students are headed to the buses tomorrow morning. Also, keep in mind that models have a hard time picking out which areas will see temps at our below freezing, I’m convinced that tonight we could see snow, especially in valley areas. but I’m thinking more in the form of light flakes because there will be some drier air to tackle with. By 7am tomorrow morning much of central and northern Kentucky could be seeing rain and possibly soggy wet snow flakes. There is BUST potential with this, because like I said temperatures will be key on who gets what.

The School Watch Meter is at a  4/11 and here’s why:

           I do believe there is potential for a school delay tomorrow morning, rain and snow leads to messy road conditions. However, my confidence on this forecast is at 60%.

          Yes, I think we’ll see snow, I don’t honestly don’t think it will be enough snow to close school

          There is definitely freeze potential, anything that falls could freeze and stick on the pavement

           There is a possibility for a school delay but it is not guaranteed

School watch meter Thursday

 

This is what I’m sticking with, do your homework! If there actually happens to be a school closing. better safe than sorry!

 

 

Updated Stab at Snow Totals

3:40p 02/14

Happy Valentines Day! Snow is working its way through the area, and there’s already reports of areas getting in with a few inches of snow soo far, especially in southern Kentucky, moderate to heavy bands of snow is moving through that area now, which has prompted me to update you on what i’m thinking soo far. I am HIGHLY confident that areas in southern and central Kentucky, including Bowling Green could get 5+” of snow. As for central Kentucky, 4″-6″ looks likely as well by Monday morning. Keep in mind the heavier totals are south of I-64.  Have a great evening and stay safe!

Tracking a possible Snow Threat..

4:00pm 02/13/16

Good Saturday Afternoon! I’m going to talk through with you about what we’re expecting for the next couple of days. First off, friends and neighbors have been asking me about this snow system expected to impact the area, well.. here are my thoughts

Sunday afternoon into Monday snow will swivel from northwest to southeast, along with that, a strengthening southern flow of warmer saturated air , and looks likely to bring some heavy snow for most of the bluegrass. This particular parameter shows the potential lifting, this system has. Notice the “tounge” is coming in from the south, which indicates that there is energy to work with in the atmosphere, just enough to cause heavy banding of snow.

Theta-E Nam Monday morning

Now I’m going to give you a run through on the timing of this .

Newest runs suggest the timing of the snow moves in Northwest to Southeast from 7-10 am. This is from the NAM.. Notice by Sunday evening, the entire state is covered with snow, and it will be a battle between the warmer and colder air to determine whether or not several areas will see mixing.

The NAM is also showing interesting snowfall totals across the region.

With that being said, here are my first thoughts on the snow Sunday through Monday.

This could very well change, check back with me later tonight to see if my thoughts stay the same!

Tracking Snow and the School Watch Meter.

6:05PM 02/28/16

Good Monday evening! Snow showers are taking over of the region, not to mention the increasing instability. Here is what I’m tracking soo far…

bwg_None_anim.gif

 

I’m also hearing reports of thunder snow out of this, which wouldn’t surprise me considering the steep lapse rates, which indicates that the air is very unstable. Similar to what you would see on a springtime forecast for thunderstorms, except, this is snow. With rates like these, Its possible we could see “Thundersnow”, in which I’m already hearing reports of in parts of central Kentucky.

lapse rates.jpg

The series of light to moderate and even heavy periods of snow will continue, I think the best chance for accumulating snow is overnight and through your Tuesday as temps drop into the 20s. The GFS snowfall accumulation forecast suggests the possibility of 1”-2” of snow generally for most of Central Kentucky by Tuesday afternoon. Snowfall ratios expected around 10 to 1.

A Winter Weather Advisory is now in effect for the area and continues through Tuesday evening.

Scott County Students, I know the real question is whether or not you’ll get a snowday. While there is still impending winter weather expected, I’m hesitant on saying you have a HIGH chance for a Snowday, however I think you have a GREATER chance for a delay.       

School Watch Meter Tuesday.jpg

School Watch Meter

 

          Overnight- early tomorrow morning snow showers move through with reduced visibilities causing hazardous travel. BUT, it all depends on the efficiency of the road crews; how well they are able to treat the roads allowing school systems to assess whether or not to cancel or remain on the delayed schedule.

          You’re not getting the full 1”-2” at once, however some areas could see a half- inch to an inch  of snow during the morning drive. It’s going to accumulate throughout the day giving road crews time to continuously treat the roads.

 

With that being Said… Tuesday’s School Watch Meter is at a 6 out of 11 chance for a Snowday. I also want to put out a disclaimer, I’m not in charge of closing the schools, if they do decide to close, I think it would be safer for them to do so…. Have a safe night and enjoy the extra sleep! 🙂

Severe Weather Threat Tuesday

8:30P 02/01

It’s been an exceptionally pleasant weekend, today also wasn’t too bad despite the morning showers. If you haven’t been outside already, you’ve wasted your time, that being said. I’m watching potent weather arriving here tomorrow.

SPC outlook 2(2)

SPC Preliminary Severe Weather Threat, Foot’s Forecast | Central Kentucky

 

 

Last update, you remember me touching base on this, and it’s likely that tomorrow winds and heavy rain will rough us up a bit. The Storm Prediction Center highlights most the Mississippi valley under some type of risk for severe weather tomorrow. The city of Lexington is under a Slight risk of severe weather, the cities of Bowling Green and Louisville are under an Enhanced risk of severe weather. The primary threat is damaging winds, and you can’t rule out the chance for possible spin up tornadoes.

ECWMWF highs

ECMWF MAX-TEMPS, WxBell

 

Not to mention, tomorrow’s highs in the mid to upper 60s to possibly even 70.

There is no doubt about the severe weather potential that we have:

 

  1. We have a convergence of warmth surging in from the southwest.
  2. Significant daytime heating for this time of year, (temps around 65 degrees).
  3. Increasing surface temps will also increase lifting in the air.
  4. Behind that, cooler air on tap.
HiRes-Model-run

NAM 4KM Simulated Radar, WxBell

 

The WxBell HiRes Nam shows that some showers may start as early as 7 or 8 am, that won’t be the thing to worry about. The bigger threat arrives around 5-7pm, storms will push in from the southwest and track towards the north- east. Gusts are expected to be around 40-50+mph.

Just How Warm are we going to get?

11:15 AM  01/29 Good Friday morning! I’m going to be brief because I have to get back to my homework, I’m posting about this because I feel like its worth sharing. Starting  tomorrow and into early next week a dramatic spike in temperatures are expected.

The EURO,( which is really good on picking up temp trends) is showing some extreme warmth set up for Kentucky, especially for this time of year.

Saturday: The Euro is putting highs in the mid 50s for the area, not to mention we’ll have pleasant conditions as well..

euro highs

ECMWF Surface Temps Saturday, WxBell

Sunday and Monday highs will stay in the 50s, rain showers arrive Sunday evening, and exit by Monday afternoon.

 

Now on to  Tuesday. Tuesday evening temps could be well into the 60s. The Euro shows a high-budget temperature wise, putting highs in the upper 60s near 70..

Tuesday highs euro

ECMWF Surface Temps Tuesday, WxBell

 

BUT.. The Canadian and GFS are putting highs in the upper 50s to lower 60s on Tuesday. quite opposed to the upper 60s. I think there’s a good shot at us reaching the mid 60s.

However, one thing they all agree with is a system bringing a whole lot of wind and rain late Tuesday night into early Wednesday morning. Followed by a  sharp crash in temps, by Wednesday afternoon temps could be in the low 30s, and thing is, we’re not done yet.

A push of Arctic air continues to move through the Midwest, and  there is a possibility that next Friday’s highs could be in the upper teens to lower 20s.
