Seven Day Hazardous Weather Outlook

1. Is lightning in the forecast? YES.   Lightning is possible today into tomorrow.  Lightning is possible this coming weekend.  I will keep an eye on Sunday and Monday.

2.  Are severe thunderstorms in the forecast?  MONITOR.  There is a low end risk of severe weather over Missouri this afternoon and tonight.  There is a low end risk of severe weather over Kentucky and Indiana Tuesday late morning and afternoon.  The main concern will be gusty wind and perhaps a report of hail.

I will keep an eye on early next week.

3. Is flash flooding in the forecast? NOT AT THIS TIME. Locally heavy rain is possible Monday and Monday night, but the risk of flooding appears low.

4. Will non-thunderstorm winds top 40 mph?  YES. Winds will gust above 40 mph today and tonight.  These will be gradient winds because of the deep area of low pressure.

5. Will the heat index exceed 100 degrees?  NO.

6. Will the wind chill dip below 10 degrees?  NO.

7.  Is measurable snow and/or sleet in the forecast?  NO.

8.  Is freezing rain/ice in the forecast? NO.  
Freezing rain is rain that falls and instantly freezes on objects such as trees and power lines  Freezing fog possible, as well.

.

Fire weather risk level.

Monday through Monday night:  3Very low risk.
Tuesday: 3. Very low risk.
Tuesday night:
3Very low risk.

Fire Weather Discussion

An approaching storm system will spread rain and maybe a few thunderstorms into the region later today into tonight. Expect strong winds today, especially late this afternoon and into this evening, sustained 20 to 30 mph and gusts 40 to 55 mph. Strong transport within a modest mixed layer should yield very good dispersion both today and Tuesday.

Gusty north winds and low RH are forecast Saturday behind a cold front. This should lead to good smoke dispersion despite modest mixing heights.

A Haines Index of 6 means a high potential for an existing fire to become large or exhibit erratic fire behavior, 5 means medium potential, 4 means low potential, and anything less than 4 means very low potential.

Beau’s Forecast Discussion

Good day, everyone.

We have a windy day ahead of us.

Southerly winds of 25 to 40 mph will be common.  Occasional gusts above 40 mph will be possible.

First, let’s look at radar.  You can see the storm system to our west.  Widespread showers and thunderstorms.  Widespread snow from Canada to Mexico.

Blue and purple represent snow.  Green would be the rain.

Locally, we don’t have to worry about snow, thankfully.

We will, however, have showers and thunderstorms developing from west to east.

Precipitation coverage will increase this afternoon into tonight.

6 AM radar animation.  What radar was showing at 6 am.

A wind advisory blankets the region.  A high wind warning for the Bootheel and a small portion of northwest Tennessee.

The high warning is where winds could gust above 50 mph!

Here is the NAM model showing wind gusts and timing.  The time is in Zulu.

Rainfall totals

Here is the WPC NOAA rainfall outlook.

Double click images to enlarge them.

We need rain.  We are still in drought.

A few of the thunderstorms could be strong this afternoon and evening.  Perhaps bringing down some gusty winds.  Brief heavy rain and lightning, as well.  I can’t rule out a severe thunderstorm warning.

On Tuesday, a second line of storms is forecast to form over portions of Indiana and Kentucky.  If the front speeds up, then my area won’t be impacted by this.  I will need to monitor it.

That line of storms could produce a few reports of hail and damaging wind.

The Storm Prediction Center has a level one risk for portions of northwest Kentucky Tuesday late morning into the afternoon hours.

Let’s look at a couple of models concerning the Tuesday storms.

These first two models show the line forming to the east of my forecast area.

I will keep an eye on it.

This last one shows it forming in south central Kentucky down into Tennessee.

All data shows Tuesday’s event being fairly far east.

Conditions dry out Tuesday from west to east.

The bulk of this rain event is this afternoon and tonight.

It will be chilly Tuesday and Wednesday night.  I can’t rule out frost if the wind subsides.

Lows will dip into the 30s both nights.

A slow warming trend Thursday into the weekend.

I am watching another storm system Sunday into Monday with perhaps some showers and thunderstorms.

Highs Friday into Monday are likely to rise into the 70s.  Perhaps mid 70s for the weekend with lows in the 50s.

Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.

One is the lowest risk. Five is the highest risk.
