This forecast update covers far southern Illinois, far southeast Missouri, and far western Kentucky. See the coverage map on the right side of the blog

9 AM UPDATE 
MONDAY

Thunderstorms possible over the next 24 hours

Monday, February 6, 2017: Severe Weather Update. This update was issued at 8:45 AM and will expire at 1 PM. A new update will be issued at 1 PM.

Concerns:
1. Medium confidence. Strong storms are possible on Monday night and Tuesday morning. The main concern will be hail. A secondary concern will be a few storms producing damaging winds. A non-zero tornado risk.

2. High confidence. Gradient winds, in response to a deep area of low pressure, will develop Monday night into Tuesday. Winds could top 40 mph tonight (these would be non-thunderstorm winds).

3. Low confidence. Thunderstorms on Tuesday could also be strong. Some storms could produce hail and damaging winds. A non-zero tornado risk.

A complicated weather forecast for the next 36 to 48 hours.

Today:

Mild air will continue to pour into the region from the south. Temperatures this morning are already WELL above normal. Normal high temperatures, for this time of the year, are around 45 degrees. We are already above that.

Highs today will top out in the upper 50’s to lower 60’s. A few spotty showers and thunderstorms will be possible. The storms, before sunset this evening, should remain below severe levels. Many areas may remain dry.

Tonight: The low-level jet will increase tonight. Dew points will be on the rise. Lift will develop. CAPE (energy for storms) will develop above an inversion. We call this elevated CAPE. Elevated CAPE typically means a hail threat.

Some of the storms tonight could produce hail. The risk for damaging winds and tornadoes is low tonight, but not zero. Since the CAPE is elevated, that should reduce the tornado risk tonight. It would also mitigate the damaging wind threat.

Keep in mind, gradient winds will be strong tonight. You can expect gusts above 40 mph. Gradient winds are produced when an area of low pressure and/or high pressure produces rapidly falling or rising barometric pressure readings. The tighter the gradient, the stronger the winds.

Tuesday:

A cold front will push into our region on Tuesday. The atmosphere will become more unstable. CAPE will be surface based on Tuesday. If that does occur then all modes of severe weather would be possible. Hail, damaging winds, and an isolated tornado risk.

Confidence is low concerning Tuesday’s forecast. Not all of the ingredients are lining up perfectly for severe thunderstorms. With that said, enough ingredients are coming together, that we should pay attention.

Severe weather is not uncommon, during the Month of February, in our local area.

Monitor updates.

An explanation of what is happening in the atmosphere over the coming day

whatamiconcered

Three concerns

  1.  High winds possible on Monday night.  Wind gusts above 40 mph are likely.  Some gusts to 50 mph possible.  These will be gradient winds.  Gradient winds are because of tight pressure gradients.  Rapidly rising or falling pressure readings.
  2.  Thunderstorms on Monday night and Tuesday morning could produce large hail.  Can’t rule out high winds from some storms, as well.
  3.  On Tuesday there should be a second round of storms.  We will need to monitor the severe weather risk, as well.

 

2014-11-24_13-38-04

Severe thunderstorm outlook.

Remember that a severe thunderstorm is defined as a thunderstorm that produces 58 mph winds or higher, quarter size hail or larger, and/or a tornado.

Sunday night into Monday:  Severe weather is not anticipated.

Monday night:  Some storms could produce hail.  High winds because of a tight pressure gradient.

Tuesday:  A few thunderstorms could become severe.  Large hail is the main concern and then strong winds.  There is a non-zero tornado risk on Tuesday.  That means that I can’t rule out isolated reports of tornadoes.  It only takes one tornado to cause problems.

Analysis

Sunday night
Confidence:  High

Clouds will be on the increase Sunday night and Monday morning.  Some spotty light showers will also be possible.  Many areas may remain dry, but radar should have at least some patchy precipitation.

Temperatures will be above normal on Sunday night.  Mt Vernon, Illinois area will dip into the middle and upper 30’s, Paducah will likely remain in the 38 to 44 degree range, and northwest Tennessee should remain in the 40’s.  Normal low temperatures, for this time of the year, are around 25 degrees.

Monday
Confidence:  High

Interactive Weather Radar Page.  Choose the city nearest your location:  Click this link

Clouds will continue to increase and thicken on Monday.  There will be at least a chance of spotty showers, as well.  I can’t completely rule out a thunderstorm.  Thunderstorm chances will be higher on Monday night and Tuesday.

Temperatures will be mild with highs in the middle 50’s to lower 60’s.  Not bad for February!  Par for the course.  The non-winter continues.

Check out this map.  This is the temperature anomaly map for Monday

Temperatures will be anywhere from 10 to 20 degrees above normal.

You know who would like this weather?  Olaf!

Rainfall totals on Monday, for those who pick up a shower, will be less than 0.15″.

Here is the 7 a.m. Monday future-cast radar

You can see a few spotty showers dotting the map.  Not much.

Here is the 12 p.m. future-cast radar.  Again, not much, but a few showers.

Here is the 4 pm future-cast radar.  Monday afternoon.

Check out the 5 p.m. temperatures.  Monday evening.  Well above normal.

Monday night
Confidence:  High

Warmer air will continue to filter into the region on Monday night.  The atmosphere will become increasingly unstable.  Showers and thunderstorms will dot radar.

There will be elevated CAPE on Monday night.  CAPE is a measure of instability.  Higher CAPE numbers typically mean better chances for strong thunderstorms.  This is especially true as wind fields aloft increase.  CAPE – what is it?  Link

Hail might be the end result.

Some of the thunderstorms, on Monday night, could produce quarter size hail or larger and gusty winds.  Medium confidence that there will be some hail late Monday night into early Tuesday morning.

In addition to the threat for thunderstorms, there will also be strong gradient winds.

What are gradient winds?  Gradient winds are caused by tight pressure changes.  The tighter the pressure change the strong the winds.  Winds will likely gust above 40 mph on Monday night and could top 50 mph in spots.

Here is the pressure map for Monday night.  The lines are isobars (equal lines of pressure).  Tight!

Click the maps to enlarge them

Here is the NAM wind gust map for Monday night

Lapse rates will be fairly high on Monday night.  What are lapse rates?  Lapse rates have to do with the change of temperature with height.  A rapidly cooling temperatures aloft is an indicator of unstable air.  More information here – click

Here is the lapse rate map for Monday night at 12 a.m. (Tuesday morning)

Tuesday 6 a.m.

Monitor updates concerning the potential for some strong storms on Monday night.

Tuesday
Confidence:  Low to medium

The forecast becomes increasingly complicated on Tuesday.  A cold front will enter our region from the west.  A deep area of low pressure will pass to our north.

We will be on the warm side of this system.  High temperatures will peak in the upper 60’s on Tuesday ahead of the front.  Some areas could reach 70 degrees.

Obviously, 70 degrees in February is never a good thing.  Thunderstorms could form along the front on Tuesday.  There remain significant questions on both coverage and intensity.

There will be some ingredients for severe thunderstorms, but whether it all comes together is still a question.  Monitor updates.  Winter months can and often do produce severe weather in our region.  It is not unusual.

The primary concern would be hail and gusty winds.  There will be an isolated tornado risk.  As always, it only takes one tornado to cause problems.

Let me show you a few maps

This is the 3 AM Tuesday CAPE map and barometer

This is quite a bit of CAPE for overnight hours.  Look how tight the pressure lines are (isobars).

CAPE – what is it?  Link

IGNORE the 11:13 AM time stamp on these graphics (I meant to take that off)

6 AM on Tuesday.  CAPE numbers

12 PM Tuesday CAPE

3 PM CAPE numbers for Tuesday

The models briefly stall the front over western Kentucky into the Bootheel on Tuesday evening.  This will need to be monitored.

9 PM Tuesday night

Obviously, there is enough CAPE for some concerns.

Dew points will peak in the upper 50’s to perhaps around 60 degrees.

Here is the 12 pm dew point map for Tuesday

Here is the dew point map for 9 pm on Tuesday.  Notice how the front starts to stretch more southwest to northeast

I typically look for 58 degrees and above (dew points) when it comes to severe weather (during the winter months).

There will also be quite a bit of wind shear.

The bottom line is that some of the storms on Tuesday could produce large hail, strong winds, and there is at least a non-zero tornado risk.

Monitor updates.

I will be using the texting service to alert people of severe weather and tornadoes.   Make sure you have signed up for the texts.  Make sure text option one is on.  That is the most important text option.

We have regional radars and local city radars – if a radar does not update then try another one. Occasional browsers need their cache cleared. You may also try restarting your browser. That usually fixes the problem. Occasionally we do have a radar go down. That is why I have duplicates. Thus, if one fails then try another one.

During the winter you can track snow and ice by clicking the winterize button on the local city view interactive radars.
