February 20, 2011: Systems to watch - heavy rain threat potential late this week...

February 20, 2011

6 PM Update

A storm system will approach the region on Thursday and Friday (February 24th/25th) .

This system has the potential to produce widespread rain across the region. Some of this rain may be heavy at times.

There will be a risk for thunderstorms with severe weather if the area of low pressure tracks through or to the north of Kentucky.

The potential exists for several inches of rain on Thursday through Friday. This may cause flash flooding and/or general flooding.

Now is the time to review severe weather awareness information and remind everyone of the dangers of crossing flooded roadways.

Good afternoon everyone!

Warm!  Temperatures have risen into the upper 60s and lower 70s over the region.  Winds are gusting in the 20-30 mph range.  Higher gusts will occur over the coming hours.  Main concern would be those out on area lakes.  Use some caution.

Here is one of the high resolution models that I use - this is wind gust map - for the coming hours.  You can see some 30+ colors in there (scale is at the bottom of the map) - click map for full image (again this is all best viewed with Mozilla Firefox)

Strongest winds should be between 2 pm and 5 pm.

























Rain likely on Monday - rainfall totals of 0.10-0.30"

Our big storm that we have been talking about is starting to take shape for THU and FRI.  A severe weather event is likely over portions of the Ohio Valley and Mississippi Valley.  Exact track of the storm will be key.

The Storm Prediction Center is already talking about a potential for supercells and tornadoes.

Still days away but let's all start thinking about the potential for an event later this week.

Remember that we need storm spotters!  Accurate information on hail size, wind damage, flash flooding, wall cloud and funnel cloud reports, tree limb size if tree limbs fall.  All of this information helps us with the warning process.

Some more information on what to report (I may work on a page for you guys - see if I can come up with something)

For those out on the rivers and lakes - please be aware that winds will gust between 30-40+ mph on Sunday and Sunday afternoon.  

Use caution on rivers and lakes.

Remember that there are burn bans in effect - please don't burn brush or other.

I am increasingly concerned about the possibility of thunderstorms and heavy rain next Thursday and Friday.  Flash flooding could be a concern for portions of the Ohio Valley.  This event will need to be monitored in the coming days.

It is still too early to determine whether severe thunderstorms will develop late next week - again we will need to fine tune this part of the forecast.
