NWS Forecaster Discussion
355 fxus63 kdvn 181643 afddvn Area forecast discussion National Weather Service quadrant cities Iowa Illinois 1143 am CDT Friday Jul 18 2008 Update... have updated Flash Flood Watch to begin at 7 PM this evening and have also added a few more counties. Short wave seen on visible satellite moving across Iowa and northern MO producing stratiform rain over portions of southern Iowa. Low level flow is weak and have not had any lightning. Plenty of cloud cover also keeping airmass from destabilizing. Therefore the threat of heavy rain has diminished for this afternoon. However with rain area moving northeast into parts of the dvn County Warning Area and breaks in the clouds will continue with likely probability of precipitation for showers and a few thunderstorms. Also any leftover boundaries may ignite some convection. Widespread two to four inches of rain fell last evening in our northwest and western County Warning Area. Flash flood guidance values are less than 2 inches. Another short wave seen to the west in South Dakota continues to generate an area of thunderstorms as it heads in our direction. With the short wave tonight and low level jet intensifying the threat of heavy rain and flash flooding will increase. Airmass very moist with precipitable waters over 2 inches which is over 150 percent of normal. Deep moisture in the column will support torrential rains. && Aviation... MVFR conditions occurring at kcid and kdbq where ground is moist from last nights rains. These sites will have occasional broken MVFR ceilings this afternoon. Kmli and kbrl will have VFR conditions with middle and high level clouds. An area of showers and a few storms will be over the region this afternoon with a larger area of thunderstorms developing this evening and overnight. && Dvn watches/warnings/advisories... Iowa...Flash Flood Watch from 7 PM CDT this evening through Saturday morning for Benton-Buchanan-Cedar-Delaware-Iowa-Jefferson- Johnson-Jones-Keokuk-Linn-Washington. Illinois...none. MO...none. && $$ Haase
