NWS Norman, OK wrote its last area forecast discussion before the first event at Jan 31, 9:53 PM CST, 2 hours 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 953 PM CST SAT JAN 31 2015 .DISCUSSION... THE LARGE AREA OF RAIN CONTINUES TO SHIFT NORTHEAST WITH TIME. THERE ARE INDICATIONS IN MODELS THAT SOME REDEVELOPMENT WILL OCCUR OVER WESTERN OKLAHOMA/WESTERN NORTH TEXAS LATER TONIGHT...ALTHOUGH ISENTROPIC LIFT APPEARS TO END AFTER MIDNIGHT. WILL LEAVE AT LEAST A SLIGHT CHANCE FOR RAIN OVER MOST OF OUR FORECAST AREA FOR THE REST OF THE NIGHT...WITH HIGHEST PROBABILITIES IN THE EAST. FOG IS DEVELOPING IN A FEW SPOTS IN WESTERN OKLAHOMA AND WESTERN TEXAS. THE MOIST ADVECTION THAT WILL CONTINUE OVERNIGHT MAY LEAD TO ADVECTION FOG. THIS IS MOST PROBABLE WEST OF I-35. HAVE MADE ADJUSTMENTS TO THE RAIN AND FOG FORECASTS FOR TONIGHT...TO REFLECT THE LATEST EXPECTED TRENDS. && .PREV DISCUSSION... /ISSUED 455 PM CST SAT JAN 31 2015/ AVIATION... STILL EXPECT SITES THAT ARE NOT IFR TO DROP INTO IFR CAT THIS EVENING WITH REGARDS TO CEILINGS. LIGHT RAIN AND SOME VIS RESRICTIONS WILL LINGER THROUGH OVERNIGHT BEFORE COLD FRONT SWEEPS SOUTH. THIS WILL AID IN IMPROVING SFC VISIBILITY AND WILL BRING IN SOME DRIER AIR THAT WILL ALLOW CEILINGS TO RISE BACK INTO MVFR CAT BEFORE CLEARING DURING THE LATTER PART OF THE FORECAST. 30 PREV DISCUSSION... /ISSUED 239 PM CST SAT JAN 31 2015/ DISCUSSION... RAIN CHANCES AND FOG POTENTIAL TONIGHT ARE THE FIRST CONCERNS... THE POSSIBLY STRONG WINDS ON SUNDAY. LATEST RADARS AND OBSERVATIONS DEPICTED MAINLY LIGHT RAIN ACROSS MUCH OF THE AREA AS OF 230 PM. THIS RAIN WILL CONTINUE TO SPREAD EAST FOR THE REST OF THIS AFTERNOON AND EVENING. TOTAL RAINFALL IS EXPECTED TO GENERALLY BE IN THE 0.25 TO 0.75 INCH RANGE. LATEST HRRR AND NAM12 HINTED THAT THE RAIN MAY GET A BIT HEAVIER OVER THE NEXT SEVERAL HOURS NEAR AND EAST OF I-44 POSSIBLY DUE TO AN INCREASING LOW LEVEL JET. RAIN WILL END WEST TO EAST TONIGHT...POSSIBLY A BIT FASTER THAN PREVIOUSLY FORECAST WITH MOST RAIN ENDING BETWEEN 9 PM AND MIDNIGHT NEAR THE I-44 CORRIDOR INCLUDING OKLAHOMA CITY... LAWTON...AND WICHITA FALLS AREAS. SOME DRIZZLE AND FOG WILL LIKELY LINGER AFTER THE RAIN ENDS. ADDED FOG MENTION TONIGHT INTO SUNDAY MORNING ACROSS THE AREA...THOUGH DOUBT THE FOG WILL BECOME DENSE WITH VISIBILITIES GENERALLY IN THE 1/2 TO 3 MILE RANGE. SNOW CHANCES LATE TONIGHT INTO SUNDAY MORNING APPEAR TO BE LOW AS THE ATMOSPHERE MAY BE TOO WARM. IF IT OCCURS...LOCATIONS NEAR ENID AND PONCA CITY MAY SEE A FEW FLAKES MIXED IN WITH ANY LINGERING LIGHT RAIN SOMETIME BETWEEN 6 AND 10 AM SUNDAY MORNING. NO ACCUMULATION IS EXPECTED DUE TO THE LIGHT INTENSITY OF ANY SNOW AND WARM GROUND TEMPERATURES. GENERALLY WENT WITH THE WARMER SIDE OF GUIDANCE LOWS TONIGHT DUE TO ABUNDANT LOW LEVEL MOISTURE. A COLD FRONT WILL BRING INCREASING NORTH TO NORTHWEST WINDS LATE TONIGHT INTO SUNDAY WHICH WOULD BREAK UP ANY FOG. THINK IT WILL ARRIVE IN NORTHWEST OKLAHOMA BETWEEN 2 AND 4 AM TONIGHT...THEN THROUGH DURANT BY 11 AM SUNDAY. SUNDAY WILL BE BREEZY TO WINDY AND COLD WITH CLEARING SKIES. GUSTS MAY BE IN THE 40 TO 45 MPH RANGE ACROSS MUCH OF THE AREAS WEST OF I-44...SO A WIND ADVISORY MAY BE NECESSARY. DID NOT ISSUE ONE AT THIS TIME AS NOT SURE ABOUT HOW MUCH VERTICAL MIXING WILL OCCUR...ESPECIALLY WITH WET GROUND FROM TODAY/S RAINFALL. HIGHS WILL AVERAGE ABOUT 10 DEGREES BELOW AVERAGE. LIGHT PRECIPITATION MAY LINGER EAST NEAR AND EAST OF I-35 DURING THE MORNING HOURS. SUNDAY NIGHT WILL BE MOSTLY CLEAR AND COLD WITH LOWS IN THE TEENS AND 20S. WINDS WILL DIMINISH THROUGH THE NIGHT. MONDAY THROUGH TUESDAY NIGHT...DRY AND QUIET WEATHER CAN BE EXPECTED. TEMPERATURES WILL BECOME ABOVE AVERAGE BY TUESDAY. WEDNESDAY AND THURSDAY...ANOTHER COLD FRONT WILL ARRIVE AND POSSIBLY BRING THE NEXT CHANCE FOR PRECIPITATION...THOUGH THE AMOUNT OF AVAILABLE MOISTURE REMAINS VERY UNCERTAIN. KEPT LOW PRECIPITATION CHANCES IN THE FORECAST FOR NOW. LOWERED TEMPERATURES ON WEDNESDAY WITH A FASTER ARRIVAL OF THE COLD FRONT. FRIDAY AND SATURDAY...DRY AND WARMER WEATHER ARE FORECAST. WENT CONSERVATIVE WITH TEMPERATURES FOR NOW THOUGH THE 12Z ECMWF MODEL DEPICTED MUCH WARMER READINGS THAN CURRENTLY FORECAST. FIRE WEATHER CONCERNS MAY BECOME ELEVATED.
