935 AM PDT MON OCT 19 2015 Other than a few lingering showers mainly in the northern Sierra today, warmer and drier weather along with breezy north winds develop across the region early this week. Some moisture and instability is still forecast to rotate on the backside of the upper low over NV to warrant some low PoPs in the Siernev today. In addition with a sheared or stretched out vorticity lobe dropping Swd along the CA coast on the backside of the larger scale upper trof this afternoon. some (not all) of the higher resolution progs suggest enough moisture and instability will be evident over the coastal range for a "pop-up" shower or two as well. Most of the region will see a return of more sunshine, drier weather, and a little warmer temperatures today. Warmer and drier conditions develop beginning Tuesday.

At the surface, high pressure will dominate with weak northerly flow. Expect a slightly warmer afternoon today, with highs reaching the low to mid 60s, warmest across the Big Bend of Florida.
Southwest winds will increase to 25 to 35 mph mainly near and east of Garden City to Elkhart, with lighter winds west nearer the trough. Model dewpoints look to high especially with the new NAM model, and have used the lower Allblend dews which look more reasonable. The only record could be at Garden City with 76 degrees, while other records are in the low to mid 80s.

WITH NEAR RECORD HIGH TEMPERATURES IN THE LOWER TO MID 70S ACROSS PORTIONS OF THE FORECAST AREA. BUT HAVE GONE AHEAD AND ISSUED A RED FLAG WARNING MAINLY FOR THE SAKE OF CONTINUITY AS IT CANNOT BE COMPLETELY RULED OUT GIVEN THE TENDENCY FOR OBSERVED CONDITIONS TO BE GENERALLY WARMER. BRINGING A COLD FRONT ACROSS THE AREA AFTER MIDNIGHT.
ANOTHER TRANQUIL DAY IS EXPECTED ACROSS THE REGION AS HIGH PRESSURE REMAINS IN CONTROL.
/ISSUED 954 PM CST FRI FEB 26 2016/ HIGH PRESSURE REMAINS OVER THE MIDSOUTH THIS EVENING. HIGH PRESSURE WAS CENTERED OVER THE ARK-LA-TEX AREA THIS AFTERNOON.

956 PM PST FRI FEB 26 2016 Our weather pattern will become breezy at times over the weekend with chances for rain in the lowlands and accumulating snow in the mountains. Evening update: Infrared satellite shows an unorganized upper trough moving into the region. Rain and high mountain snow will increase over the Idaho Panhandle early Saturday when the trough axis swings inland and upslope flow increases.
WARM AIR ADVECTION WILL CONTINUE TODAY AHEAD OF AN APPROACHING LOW PRESSURE. COLD AIR ADVECTION COULD CHANGE RAIN TO SNOW OR FREEZING RAIN ACROSS AREAS NORTH AND EAST OF THE MISSOURI RIVER. ONLY MINOR AMOUNTS OF PRECIPITATION ARE ANTICIPATED WITH THIS SYSTEM DUE TO LIMITED AVAILABLE MOISTURE IN THE LOWER ATMOSPHERE.
400 AM CST SAT FEB 27 2016 AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL TRANSITION ACROSS THE PLAINS TODAY. WITH WARMER AIR ADVECTING IN FROM THE WEST IN THE LOWER LAYERS OF THE ATMOSPHERE. EXPECT THIS WARMER AIRMASS TO HELP TEMPERATURES CLIMB WELL ABOVE NORMAL BY MID AFTERNOON. WITH HIGH TEMPERATURES PEAKING IN THE LOWER 70S FOR MOST LOCATIONS. EXPECT THE PRESSURE GRADIENT TO STRENGTHEN OVERNIGHT AHEAD OF AN APPROACHING COLD FRONT. WITH LOW TERMPERATURES EXPECTED TO BOTTOM OUT IN THE LOWER TO MID 40S AT MOST SPOTS.
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
Temps will be slightly cooler in areas where some snow cover remains. Mid level ridge shifts eastward over the region for a warming trend throughout the weekend.
HAVE MADE ADJUSTMENTS TO THE SKY GRID AS MID AND HIGH CLOUDS CONTINUE TO INCREASE AHEAD OF THE APPROACHING UPPER TROF. UPPER TROF MOVES TO WESTERN MONTANA BY TOMORROW MORNING.
400 AM CST SAT FEB 27 2016 MAIN ISSUE THE NEXT 12-24 HOURS IS TIMING THE COLD FRONT DROPPING SOUTH AND ITS IMPACT ON TEMPERATURES. A COLD FRONT IS DROPPING SOUTH THROUGH CENTRAL MANITOBA AT THE PRESENT TIME WITH A 20 DEGREE DROP IN TEMP IN 1-2 HOURS. THE COLD FRONT WILL CONTINUE TO MOVE SOUTH TODAY. AS IT DOES A SHORT WAVE ROUNDING THE TOP OF A FLATTENING UPPER RIDGE OVER ALBERTA WILL DROP SOUTHEAST. THE COLD FRONT WILL ARRIVE INTO FAR NE ND/FAR NW MN NR 18Z AND THEN DROP SOUTH TOWARD GFK 21-22Z TIME PERIOD. THERE WILL BE A NARROW ZONE WITH ENOUGH MOISTURE AND LIFT TO BRING UP TO 1 INCH OF FRESH SNOW ACROSS SOUTHERN MANITOBA INTO LAKE OF THE WOODS REGION TONIGHT TO THE NORTH OF THE LOW AND INTO THE COLD AIRMASS.
TEMPERATURES WILL ALSO WARM IN RESPONSE INTO THE LOW TO MID 70S.
AN UPPER TROUGH OVERHEAD WILL BE EXITING THE AREA THIS MORNING. A BUILDING RIDGE ALOFT. RIDGING THROUGH THE COLUMN WILL PROVIDE CLEAR SKIES TONIGHT WITH LOWS IN THE UPPER 20S TO MID 30S IN MOST SPOTS.
UPPER RIDGING CONTINUES TO BUILD INTO THE MIDWEST THIS MORNING WITH AN UNSEASONABLY WARM AIRMASS MOVING IN ALOFT. THE BIG QUESTION FOR THE DAY WILL BE HOW DEEPLY DO THE LOWER LEVELS OF THE ATMOSPHERE MIX TODAY. THE FORECAST AREA WILL REMAIN ON THE MILD SIDE GOING INTO TONIGHT BEING POSITIONED IN THE WARM SECTOR OF A LOW PRESSURE SYSTEM EDGING SOUTHEAST OUT OF THE DAKOTAS. THE LOW LOOKS TO PASS DIRECTLY OVER THE AREA LATE TONIGHT CAUSING WINDS TO GO LIGHT TO CALM. AREAS THAT SAW SNOW MELT DURING THE DAY COULD SEE AREAS OF FOG DEVELOP AS THE LOW MOVES IN.
SOME NORMALLY COOLER LOCATIONS ACROSS EAST CENTRAL FL MAY REALIZE U30S FOR EVENTUAL LOWS. LUCIE/MARTIN COUNTY COASTS AND U30S POSSIBLE OVER NORMALLY COOLER/RURAL LOCATIONS OF THE INTERIOR. CANNOT RULE OUT SOME PATCHY FROST POTENTIAL IN THESE COOLER AREAS THAT REALIZE U30S OVERNIGHT.
