janetjanet998 Posted May 13, 2011 Share Posted May 13, 2011 at this time slow moving thunderstorms are developing along a front over N IL...high PW values wrapping around a slowly strengthening andvery slow moving 850mb low sometimes produce surprise flood situations.. looks slow moving thunderstorms will prime the area though this evening and then a more moderate rain event after that not a huge deal so far but something to track 12 nam has up to 3 inches over the weekend but is already missing most of the heavy rain today the NW burbs also have had heavy rain the past view days so flash flooding is possible there Link to comment Share on other sites More sharing options...

cyclone77 Posted May 14, 2011 Share Posted May 14, 2011 DVN basically says this will be a non-event for our area. Can't remember the last time this area has had anything even remotely exciting. We've been an island in the stream since the Groundhog blizzard. NATIONAL WEATHER SERVICE QUAD CITIES IA IL 858 PM CDT FRI MAY 13 2011 .UPDATE... THE UPPER LOW CONTINUES TO SPIN...BUT MOISTURE IS NOT CONSISTENT IN THE FLOW AROUND THE SYSTEM. THE INTENSE RAINS EARLIER HAS PRODUCED LARGE HOLES OF DRY AIR AT MID LEVELS THAT NO MODEL HAS A HANDLE ON. SO...THE FOLKS THAT SAW THE ISOLATED HEAVY TOTALS IN A RANDOM PATTERN OF SLOW MOVING SHOWERS EARLIER...WILL BE THE BIG RAINFALL WINNERS FROM THIS SYSTEM OVER ALL. THE REMAINDER OF THE NIGHT...WILL DECREASE POPS TO ACCOUNT FOR THE MUCH MORE SCATTERED NATURE OF THE SHOWERS...AND REDUCE THE QPF TO A FEW HUNDREDTHS...AS ONLY A FEW BANDS OF MODERATE RAIN APPEAR POSSIBLE OVERNIGHT...WITH MORE SIGNIFICANT RAIN CONFINED WELL TO THE SOUTHEAST. FOR FOLKS NEEDING RAIN...SATURDAY THROUGH SUNDAY MORNING STILL APPEARS LIKELY TO BRING WIDESPREAD LIGHT RAINS...WITH SOME MODERATE RAIN POSSIBLE AS WELL.
