WILL CONTINUE TO SHOW THIS LOSS OF ICE COMING INTO THE SOUTHEAST SECTIONS FOR A CHANGE OVER TO SOME FREEZING DRIZZLE OR FREEZING RAIN. JUST HOW MUCH BLOWING SNOW OCCURS COULD BE IMPACTED ON WHETHER THE FREEZING DRIZZLE/RAIN OCCURS AND PUTS A HARD COATING ON TOP OF THE SNOW. 12Z MODEL DATA ALSO CONTINUES TO INDICATE THE UPPER LEVEL LOW WILL BECOME AN OPEN WAVE OVERNIGHT WITH THE TAIL END OF THE SHORT WAVE TROUGH COMING ACROSS LATE TONIGHT. THE UPPER LEVEL FLOW WILL BECOME NORTHWEST BEHIND THIS SYSTEM AND STILL LOOKING AT ANOTHER WEAK SHORT WAVE TROUGH TO COME DOWN OUT OF CANADA AND MOVE ACROSS THE UPPER MIDWEST.
619 PM MST TUE FEB 2 2016 300MB TROUGH AXIS AND UNUSUAL INSTABILITY HAS LEAD TO ANOTHER EVENING OF SCATTERED SNOW SHOWERS OVER THE CENTRAL ZONES.
915 PM CST TUE FEB 2 2016 NEW INFORMATION ADDED TO UPDATE SECTION BEST FORCING AND MID LEVEL MOISTURE EXITED THE AREA EARLIER THIS EVENING AND THE SNOW HAS TAPERED OFF TO VERY LIGHT SNOW OR FREEZING DRIZZLE OVER EASTERN WISCONSIN. A WEAK DISTURBANCE MOVING ACROSS THE REGION WILL BRING ANOTHER 1 TO 3 INCHES OF SNOW AS THE LOW DEPARTS THE AREA.
The next low pressure system will be quick on its heels, moving through NorCal midday Wednesday through Wednesday night. This next system is forecast to be a bit wetter than today's, but not by much as it too will be weakened by the eastern Pacific ridge. The highest forecast snow totals are across the Shasta County mountains, where 2 to 5 inches could fall Wednesday. High pressure will begin to build into California more strongly late this week into the weekend.
THEN INCREASE WITH SECONDARY SURGE OF HIGH PRESSURE AOA 03/12Z. HIGH PRESSURE CONTINUES TO SLIDE SOUTH OVER SOUTH TEXAS THIS AFTERNOON AND EVENING. WITH A SECOND PUSH OF HIGH PRESSURE EXPECTED OVERNIGHT. THE SECOND PUSH OF HIGH PRESSURE IS EXPECTED TO BE FELT OVER THE WATERS ON WEDNESDAY WITH SMALL CRAFT ADVISORIES LIKELY NEEDED. HAVE TRENDED WITH THE LOWER SIDE OF GUIDANCE AS CAA DEVELOPS. H925 TEMPS AT 8C-10C AND H85 TEMPS AT 2C-5C WOULD SUGGEST EVEN COOLER THAN WHAT MODELS ARE OUTPUTTING. DID CONTINUE WITH DAYTIME HIGHS AT LEAST IN THE LOW TO MID 60S. A COOLER NIGHT WEDNESDAY NIGHT IS EXPECTED AS MUCH HIGH PRESSURES RESTS OVERHEAD.
AND WITH WET BULB TEMPERATURES WELL BELOW FREEZING. AND WITH TEMPERATURES NEAR THE FREEZING MARK NO SIGNIFICANT TRAVEL TROUBLES ARE ANTICIPATED. /ISSUED 312 PM CST TUE FEB 2 2016/ SURFACE MIXING HAS BEEN UNDERWAY FOR SEVERAL HOURS NOW ACROSS THE REGION MIXING ALONG WITH AN APPROACHING COLD FRONT HAS RESULTED IN FAIRLY GUSTY WINDS TODAY. THE COLD FRONT IS AT THE EDGE OF THE SOUTHERN TEXAS PANHANDLE AS OF 20Z. SURFACE PRESSURE GRADIENT WILL RELAX OVERNIGHT MAKING WAY FOR HIGH PRESSURE WHICH WILL CALM WINDS A GOOD BIT WITH THE LIGHTEST WINDS OCCURRING ALONG THE TX/NM STATE LINE. LOWS BY TOMORROW MORNING ARE EXPECTED TO BE IN THE LOW TO MID 20S AREA WIDE WITH THE EXCEPTION OF OUR NORTHWEST COUNTIES WHICH WILL SEE LOWS IN THE MID TO UPPER TEENS.
WHILE WIDESPREAD FLASH FLOODING IS NOT EXPECTED DUE TO FFG BEING ON THE HIGH SIDE. WITH THE APPROACH OF A VIGOROUS COLD FRONT AND TS ON THE DOORSTEP.
736 PM EST TUE FEB 2 2016 AVIATION LOW PRESSURE WILL BRING RAIN AND MIXED PRECIPITATION TO LOWER MICHIGAN TONIGHT. THE LOW MOVES AWAY ON WEDNESDAY BUT LINGERING RAIN AND SNOW SHOWERS WILL REMAIN.
AN ACTIVE START TO THE TAF PERIOD WITH A STRONG COLD FRONT MOVING INTO THE SOUTHERN APPALACHIAN REGION.
IN THE HIGH COUNTRY. ONLY AN INCH OR SO EXPECTED ON THE HIGHER SLOPES. DESPITE DOWNSLOPE FLOW ALL LOCATIONS ARE EXPECTED TO REMAIN BELOW FREEZING. SHOULD STILL SEE A FEW SNOW SHOWERS LINGER OVER THE HIGHER SLOPES IN THE MOUNTAINS. NORTHWESTERLY FLOW ALOFT IS GOING TO DOMINATE THE WEATHER PICTURE FOR THE NEXT SEVERAL DAYS AS A MEAN RIDGE BUILDS OVER THE WESTERN UNITED STATES.
WIDESPREAD FREEZING TEMPERATURES ARE EXPECTED LATER TONIGHT INTO WEDNESDAY MORNING. A BIT OF MODERATION IN THE AIR MASS WILL ALLOW AFTERNOON TEMPS TO PEAK ABOUT 3-6 DEGREES WARMER THAN TODAY BUT STILL ENDING UP 10-15 DEGREES COOLER THAN NORMAL FOR THE DAY.
936 PM CST TUE FEB 2 2016 RADAR CONTINUES TO SHOW HEAVIER SHRA/TSRA DEVELOPING ALONG THE VERY SLOW MOVING COLD FRONT OVER ACADIANA INTO THE COASTAL WATERS. ISSUED A FLASH FLOOD WATCH FOR THIS AREA SOUTHEASTWARD ACROSS THE LOWER ACADIANA THROUGH 4 AM. A COLD FRONT NOW APPROACHING ACADIANA WILL MAINTAIN A FEW SHOWERS AND THUNDERSTORMS OVER THE NEXT FEW HOURS. SECONDARY SURGE OF DRIER AND COOLER AIR TO MOVE DOWN ON WEDNESDAY.
619 PM EDT MON OCT 5 2015 A LARGE AREA OF HIGH PRESSURE TO OUR NORTH WILL WEAKEN AND DROP SOUTH ON TUESDAY. A MAINLY DRY COLD FRONT SHOULD PASS IN THE MIDDLE OF THE WEEK.
MUCH OF THIS ACTIVITY IS NOT REACHING THE GROUND AS THE LOWER LEVELS OF THE ATMOSPHERE REMAIN TOO DRY AND MUCH OF THE ACTIVITY IS EVAPORATING BEFORE REACHING THE SURFACE. THIS ACTIVITY IS ALL IN RESPONSE TO A WEAK IMPULSE AHEAD OF A MUCH STRONGER UPPER LEVEL LOW. THE COOLER TEMPERATURES WILL BE ACROSS THE HILL COUNTRY. WE SHOULD SEE DRY CONDITIONS TOMORROW AS WEAK UPPER RIDGING SETS UP OVER TEXAS AHEAD OF THE STRONG UPPER LOW ACROSS THE SOUTHWESTERN CONUS. THE RIDGING WILL ALLOW WARMER TEMPERATURES TOMORROW WITH PARTLY CLOUDY SKIES. ANOTHER QUIET PERIOD IS EXPECTED FOR TOMORROW NIGHT WITH LOWS A BIT WARMER.
239 PM CDT MON OCT 5 2015 Low-level moisture trapped underneath a ridge axis over the Central Plains will stay in place through much of the afternoon and evening hours. A well-defined blocking pattern with a deep mid-level low over the southeastern CONUS working opposite a deepening low over the western CONUS will remain in place through Tuesday. As the ridge axis above the Central Plains approaches the area, low-level stratus will begin to dissipate through Tuesday afternoon as dry air enters the region.
Pleasant early fall conditions will persist this week as a ridge of high pressure maintains dominance across the region.
