February 23, 2011: Heavy rain event unfolding...

February 23, 2011

11 PM Update

This is the latest statement sent out to the Transportation Cabinet

February 24, 2011 Update

A strong storm system is already spreading heavy showers and thunderstorms into Arkansas and Tennessee early this morning. This area of showers and thunderstorms will spread into Kentucky between 1 am and 5 am this morning.

Radar

Rain will come in waves today into tonight. There may be a lull in the precipitation in some of our counties on Thursday late morning and Thursday afternoon. Then more rain will spread back into the region.

Much of the State of Kentucky is now under a flash flood watch. Rainfall totals of 1-3" will likely occur in most counties. The southeast portion of Kentucky will likely be spared the excessive rains.

There will be pockets of rainfall totals of 3-5" in some of the counties within the flash flood watch. It will be difficult to determine which counties will receive the heaviest totals until the band actually sets up through the day.

In addition to the flash flood threat there will be a risk for severe thunderstorms on Thursday evening and Thursday night. This will be highly dependent on the location of the warm front and the track of the area of low pressure.

Tornadoes will be possible along and south of the warm front. The highest threat area for tornadoes will likely be in Arkansas and Tennessee. This will need to be closely monitored.

Listen to NOAA Weather Radio and local National Weather Service Offices for the latest updates as this storm unfolds through the day on Thursday and into Thursday night.

Review flash flood safety rules.

Transportation Cabinet Rainfall Forecasts

Districts 1 2, 3, 4, and portions of District 7 may experience widespread 2-3" of rain with a better chance of some 3-5" reports not out of the question otherwise


Districts 5, 6, 7, (northern part of 8) - rainfall totals of 1-3" widespread. Pockets of 3-5"+

Districts 8, 9, 10, 11, 12 - rainfall totals of 1" could be a few spots of higher rain.

Rain will move out of the state on Thursday night and Friday from west to east. The rain will move out of the eastern portion of the state by Friday afternoon.

Another large and significant weather event is likely to occur on Sunday and Monday. This storm system will spread heavy rain and possibly severe thunderstorms back into the Ohio and Tennessee Valleys. Obviously any additional rainfall on top of this first event will only compound the problems.

Additional flash flood watches and/or flood watches may be needed for Sunday and or Monday.

Transportation Cabinet Officials should closely monitor this unfolding weather situation from now into the weekend.

9 PM Update

No changes in tonights data

Main threat will be heavy rain

Questions on severe weather - most likely over the area outlined in deep red on my video update - AR/TN

Whether severe weather threat will enter KY will probably not be known until tomorrow morning.

The time period for severe weather would be Thursday afternoon into Thursday night.

Another chance for severe weather and heavy rain on Sunday/Monday

We have been advertising this next storm system for over 10 days now.  Long time - the big events always seem to be that way.

Don't forget we have also been tracking a second event for Sunday/Monday.  Another big storm is likely to occur at that time.

5 PM Update

Crunching some new numbers - I am concerned about the tornado threat for portions of AR and TN.  The question mark continues to be the Missouri Bootheel and Kentucky.

Latest data wants to shift the low a tad further north - this would definitely raise concerns for western Kentucky into south central Kentucky.

The NWS has now expanded the flash flood watch further north to include more of southeast Missouri and southern Illinois.

No change in my previous forecast for rainfall totals - if anything I have increased them since the video last night.

I will have a full update tonight between 9 pm and 10 pm and will be covering this event from early tomorrow morning right on through tomorrow evening.

For the latest watches and warnings please tune into your local National Weather Service web-site and NOAA Weather Radio.

1 PM Update

No changes - new Storm Prediction Center outlook for tomorrow shows the best risk for severe storms just south of the KY/TN line.  VERY close.

The rest of the area is in a risk for severe storms - hail and high winds being the main threat.

We will have to monitor this closely.  Tornadoes are possible tomorrow in or near our region.  Stay updated as the event unfolds.

Rainfall totals across far southeast MO and southern IL - Kentucky - Tennessee will range from 1-3" with some areas picking up 3+ inches of rain.

The new European Computer Model shows over 3" of rain for the City of Paducah.  

Flash flooding will be possible over our area (southeast MO, southern IL, Kentucky and Tennessee)

Here are some new graphics from the Storm Prediction Center - remember the SPC are the ones that issue the severe weather outlooks.  They have three levels of risk - slight and then moderate and then high.

Slight risk means that severe weather will most likely occur but not be as widespread
Moderate risk means that widespread severe weather is possible
High risk means that a significant outbreak of severe thunderstorms is likely

Don't pay too much attention to the risk levels - just remember that it means severe weather will be possible and pay attention for updates.
























The severe weather outlook for Thursday - you can see a slight and moderate risk over our area.


They also issue probabilities - you can see that they are quite high for portions of the region.  Probabilities indicate the chances of an event within 25 miles of any given point.  You can see a 45% contour on the map (again that is quite high and means that the forecasters are confident that severe weather will likely occur)  More information on this map - click here
























 And finally here is the 5 day rainfall outlook - impressive totals

10 AM

Temperatures have risen above freezing over most counties - so the threat for frozen precipitation is limited to the far northern counties.

Our big storm that we have been talking about for the last week and a half if now approaching the region.  It appears as juicy as ever.

A flash flood watch has been issued for much of western Kentucky and far southeast Missouri

The watch outline can be viewed here

Additional heavy rain is likely on Sunday/Monday.
