Gilbertfly Posted August 25, 2014 Share Posted August 25, 2014 see text added for NE IL...possible upgrade to slight later.... DAY 1 CONVECTIVE OUTLOOK NWS STORM PREDICTION CENTER NORMAN OK 1124 AM CDT MON AUG 25 2014 VALID 251630Z - 261200Z ...CNTRL PLAINS INTO UPPER MS VALLEY THIS AFTERNOON INTO TONIGHT... A NE-SW-ORIENTED BROKEN BAND OF TSTMS IS ONGOING AS OF MID MORNING FROM NRN LOWER MI TO SRN WI WITH THIS ACTIVITY LIKELY BEING FORCED BY A COMBINATION OF WAA ALONG A WEAKENING NOCTURNAL LLJ AND THE INFLUENCE OF THE MID-LEVEL TROUGH TO THE NORTH. TO THE SOUTH OF THESE STORMS...THE 12Z DVN AND ILX SOUNDINGS REVEALED THE PRESENCE OF A STRONGLY UNSTABLE ENVIRONMENT WITH MUCAPE UPWARDS OF 3500-4500 J/KG. HOWEVER...IT REMAINS UNCERTAIN AS TO WHETHER THE CURRENT STORMS WILL BE ABLE TO TAP INTO THE HIGH THETA-E RESERVOIR...DUE IN PART TO THE TENDENCY OF RISING MID-LEVEL HEIGHTS THROUGH THE PEAK OF THE DIURNAL HEATING CYCLE. LATEST CONVECTION-ALLOWING MODEL GUIDANCE IS SUGGESTIVE IN THE DEVELOPMENT OF A SWD-MOVING MCS ACROSS NRN INTO CNTRL PARTS OF IL/IND. SHOULD THIS SCENARIO UNFOLD AS INDICATED...A MORE CONCENTRATED AREA OF DAMAGING WIND POTENTIAL COULD EVOLVE...REQUIRING A POSSIBLE UPGRADE TO SLIGHT RISK WITH THE 20Z ISSUANCE.

hawkeye_wx Posted August 25, 2014 Share Posted August 25, 2014 In the thread title, what is ROF? Good recovery across eastern IA and the IA/IL border but probably done for here. We had storms and clouds into early afternoon, but once the sun came out we very quickly recovered to the mid to upper 80s. Link to comment Share on other sites More sharing options...
