LOT must of heard me rant....

Well I was sitting in the weather lab this morning with a buddy of mine ranting why LOT should have a flood watch up for the area. areas overnight got between .50 and 1.50 inches of rain with a stalled out frontal boundary across the area with dew points pooling in the upper 60's along, PWATS near 1.8 and heavy rain at the time this morning near DVN now over the LOT area. Clinton has already picked up 3.45 inches of rain.

and to add to the fact that there is a very pronounced MCV in southwest IA barely moving, this will move very slowly along the the front and will only aid in better forcing and create more heavy rain with the help of a low level jet later tonight. DVN's afd this afternoon said it could take until friday morning before the MCV moves through their CWA.

finally at 2pm today, LOT went with the flash flood watch until thursday evening (could be extended if the MCV moves that slow along the front). here is the text from the watch....

THROUGH THURSDAY EVENING*

A STATIONARY FRONT AND UPPER LEVEL DISTURBANCE WILL RESULT IN A POTENTIAL OF HEAVY RAINFALL TONIGHT INTO THURSDAY MORNING ALONG WITH A THREAT OF FLASH FLOODING. PORTIONS OF NORTH CENTRAL ILLINOIS EXTENDING INTO THE NORTHERN SUBURBS OF CHICAGO RECEIVED BETWEEN 1 AND 2 INCHES OF RAIN TUESDAY NIGHT INTO WEDNESDAY MORNING. ADDITIONAL RAINFALL AMOUNTS THROUGH THURSDAY OF 1 TO 3 INCHES ARE EXPECTED...WITH LOCALIZED HIGHER AMOUNTS CLOSER TO 4 TO 5 INCHES POSSIBLE.

as you can see on radar, http://radar.weather.gov/Conus/full_loop.php... the MCV is currently in southwest IA producing heavy rain and also the heavy batch of rain in eastern IA moving into northern IL. I wouldnt be suprised to see some totals up near the 7 0r 8 inch mark after all is said and done.

on a side note that could turn alot more interesting over the next few days, tropical storm danny is out in the Atlantic trying get its act together and should become a hurricane in the next few days and could run up along the east coast....http://www.ssd.noaa.gov/goes/flt/t1/loop-vis.html
