TEMPERATURES WILL BE NOTICEABLY WARMER THAN PREVIOUS NIGHTS ALTHOUGH THEY WILL STILL DROP OFF QUICKLY AFTER SUNSET ACROSS PORTIONS OF SOUTHEASTERN MS. LOWER LEVEL MOISTURE WILL CONTINUE TO INCREASE ON SUNDAY IN ADVANCE OF A DISTURBANCE WHOSE BOTTOM END LOOKS TO PASS ACROSS THE LOWER MS VALLEY TOMORROW NIGHT. WARMTH AND MOISTURE ADVECTION DURING THE DAY TOMORROW AND ESPECIALLY TOMORROW NIGHT (IN CONCERT WITH LIFT FROM THE PASSING TROUGH) SHOULD FUEL MAINLY ISOLATED LIGHT SHOWERS AND PATCHES OF DRIZZLE. TEMPS TOMORROW SHOULD BE EVEN WARMER THAN TODAY.
Mid afternoon temperatures were in the middle 60s to the lower 70s across the area. As temperatures cool the low levels may saturate enough to create a low level stratus deck. Another relatively warm day is in store for Sunday as a cold front makes its way across the region. However expect any stratus to erode from the west pretty quickly as the low level flow veers with the approach of the front.
THIS WAVE WILL TOP THE RIDGE OVER THE ROCKIES AND MOVE SOUTHEAST INTO THE MID MISSISSIPPI VALLEY. AT THE SURFACE THE RIDGE OF HIGH PRESSURE OFF THE EAST COAST WILL REMAIN NEARLY STATIONARY AS A COLD FRONT ASSOCIATED WITH THE SHORT WAVE MOVES THROUGH THE MID WEST. LOW LEVEL MOISTURE WILL INCREASE BRINGING WARMER NIGHTTIME TEMPERATURES AND AN INCREASE IN LOW LEVEL CLOUDS. MAIN LOW PRESSURE SYSTEM CENTERED OVER THE SOUTHERN TIP OF LAKE MICHIGAN SUNDAY MORNING. THIS LOW CENTER WILL MOVE EAST. TEMPS ALSO LOOK TO STAY WELL ABOVE FREEZING SO NO WINTRY PRECIP EXPECTED EITHER.
HIGH PRESSURE WILL SHIFT INTO UTAH TODAY ALLOWING A FEW MAINLY MOUNTAIN SHOWERS TO DEVELOP OVER THE AREA THIS AFTERNOON.
AN UPPER LEVEL DISTURBANCE ACROSS NORTHERN CALIFORNIA WILL ROUND THE TOP OF THE RIDGE OF HIGH PRESSURE ACROSS THE INTERMOUNTAIN WEST OVER THE NEXT 24 HOURS. LIGHT WESTERLY WINDS BEHIND THE WARM FRONT THAT CROSSED THE REGION YESTERDAY CONTINUE ACROSS THE LOCAL AREA THIS MORNING.
TOWARDS 12Z THE LOW LEVEL COLD ADVECTION STARTS AND THIS SHOULD HELP MIX THE LOW LEVELS AND DISPERSE ANY LINGERING DENSE FOG. HOWEVER QPF AMOUNTS ARE QUITE LOW AND MILD TEMPS AT THE OUTSET WILL HOPEFULLY KEEP ANY FREEZING PRECIP FROM BECOMING ANY KIND OF A WIDESPREAD CONCERN. WITH THE LOW LEVEL THERMAL TROUGH BECOMING ESTABLISHED CLOUD COVER WILL BE WIDESPREAD WITH ANY FOG DISSIPATING WITH INCREASED MIXING.
WITH A SHORT WAVE TROUGH CRUISING THROUGH SOUTH CENTRAL CANADA.
227 PM EST SAT FEB 7 2015 A BRIEF PERIOD OF THICKER ELEVATED CLOUDS BLOCKED THE SUN OVER PORTIONS OF THE LOWER KEYS EARLIER TODAY. LARGE HIGH PRESSURE NEAR THE SOUTHEAST COAST WILL REMAIN THE MAJOR DRIVING FEATURE FOR THE SHORT TERM PORTION OF THIS FORECAST. THIS HIGH PRESSURE WILL CONTINUE TO SETTLE TO THE SOUTHEASTWARD INTO THE ATLANTIC TONIGHT INTO SUNDAY MORNING.
THE FREEZING RAIN POTENTIAL STILL EXISTS TONIGHT. WILL BE ANALYZING THE POTENTIAL FOR A FREEZING RAIN ADVISORY TONIGHT/SUN.
434 PM EST SAT FEB 7 2015 AS HIGH PRESSURE RETREATS TO THE EAST OVERNIGHT. AN ADVANCING LOW PRESSURE SYSTEM FROM THE CENTRAL PLAINS WILL BRING RAIN TO THE REGION SUNDAY AFTERNOON AND EVENING. HIGH PRESSURE WILL THEN SETTLE IN BEHIND THE FRONT. AS THE HIGH PRESSURE RETREATS EAST OF THE AREA. WILL TAKE SOME TIME OVERNIGHT FOR THE LOWER LEVELS TO MOISTEN UP. NOT A FREEZING PRECIPITATION SCENARIO.
HIGH PRESSURE CONTINUES TO FLATTEN AS WIND FLOW BECOMES MORE ZONAL. A CHANCE REMAINS THIS AFTERNOON AND EVENING FOR SOME VERY ISOLATED SNOW SHOWERS/FLURRIES FOR THE HIGHEST ELEVATIONS OVER THE FLATTOPS AND NRN MTNS. THE JET WILL ALLOW ALSO FOR SOME GUSTY WINDS IN THE 30 TO 40MPH RANGE AT TIMES OVER THE HIGHEST ELEVATIONS. TEMPS WILL REMAIN WARM THOUGH A LITTLE COOLER TODAY AND TOMORROW BECAUSE OF INCREASED CLOUD COVER.
412 PM EST SAT FEB 7 2015 A COLD FRONT WILL DRIFT SOUTH AND STALL SOUTH OF THE REGION TONIGHT ON SUNDAY.
ISSUED A FREEZING RAIN ADVISORY FOR NORTHWEST INTO PORTIONS OF CENTRAL NORTH DAKOTA THROUGH LAKE SAKAKAWEA FROM 03 UTC THIS EVENING THROUGH 12 UTC SUNDAY MORNING. PRECIPITATION IS EXPECTED TO START OUT AS RAIN BEFORE A TRANSITION THROUGH A MIX OF FREEZING RAIN. UNCERTAINTY REMAINS AS TO HOW QUICKLY SURFACE TEMPERATURES WILL FALL BELOW FREEZING WITH 21 UTC TEMPERATURES IN THE 40S AND 50S. TEMPERATURES MAY REMAIN ABOVE FREEZING MUCH OF THE NIGHT SOUTH CENTRAL TO LIMIT THE FREEZING RAIN THREAT.
327 PM EST SAT FEB 7 2015 HIGH PRESSURE WILL PREVAIL THROUGH THE WEEKEND.
THE UPPER AIR PATTERN ACROSS THE CONUS WILL AMPLIFY EARLY IN THE PERIOD WITH AN EASTERN TROUGH AND WESTERN RIDGE THEN DOMINATING THE COUNTRY THROUGH MUCH OF THE FORECAST PERIOD.
1005 AM CST Sat Feb 7 2015 A tightening gradient between high pressure centered over Georgia and developing low pressure over the Northern Plains is creating gusty southerly winds across central Illinois this morning. Low pressure riding along the warm front currently to our north will begin to drag a trailing cold front southward across the forecast area on Sunday. Have kept the highest rain chances across the northeast third of the CWA during the afternoon. On Sunday, favored the warmer GFS MOS in the southeast with highs in the mid 50s, trailing back to the upper 30s across the northwest CWA where there will still be a decent snow cover.

HIGH PRESSURE OVER THE SOUTHEAST U. A COLD FRONT WILL DROP SOUTH TOWARD THE FORECAST AREA. TEMPERATURES WILL BE PLEASANT FOR ONE MORE DAY WITH HIGHS IN THE LOW TO MID 60S. BY SUNDAY NIGHT THE COLD FRONT WILL BE MOVING THROUGH THE FORECAST AREA WITH ANOTHER CHANCE OF LIGHT RAIN AHEAD OF THE FRONT.
HIGH PRESSURE IS NOW CENTERED FAR TO OUR SOUTHEAST WITH A LOW PRESSURE SYSTEM BREWING OVER THE UPPER MIDWEST AND A STRENGTHENING PRESSURE GRADIENT BRINGING UNSEASONABLY WARM AIR INTO MIDDLE TENNESSEE THIS WEEKEND. TONIGHT'S TEMPERATURES WILL BE CONSIDERABLY WARMER, ONLY DROPPING INTO THE 40'S MOST AREAS, WITH READINGS TOMORROW ONCE AGAIN APPROACHING 60 DEGREES, DESPITE INCREASED CLOUDINESS AND A SLIGHT CHANCE OF RAIN. A COLD FRONT WILL SWEEP THROUGH THE MID STATE TOMORROW NIGHT, WITH A BIT BETTER CHANCE OF RAIN OVERNIGHT, ALTHOUGH THE QPF FOR THIS EVENT REMAINS RATHER LOW GIVEN THAT ONLY THE LOW LEVELS WILL BE SATURATED. TEMPERATURES STARTING OFF THE NEW WEEK WILL BE CONSIDERABLY COOLER.
EXPECTING OVERNIGHT LOWS TO BE SEVERAL DEGREES WARMER TONIGHT THAN THIS MORNING GIVEN THE BETTER SURFACE MOISTURE FIELDS. APPROACHING TROUGH ON SUNDAY SWITCHING WINDS NEAR THE SURFACE AND IN THE BOUNDARY LAYER SHOULD RESULT IN WARM DAYTIME HIGHS (850 MB TEMPS 16-17 CELSIUS TOMORROW).
MID LEVEL RIDGING SHOULD REMAIN IN CONTROL THRU MIDWEEK.
A MORE SUBSTANTIAL TROUGH WILL MOVE THROUGH THE AREA LATE TONIGHT AND SUNDAY MORNING WITH STRONGER NORTHWEST WINDS.

MONDAY NIGHT THROUGH SUNDAY AS TYPICAL OF THE LOW-AMPLITUDE PROGRESSIVE FLOW. LEADING BAND OF PCPN IN ISENT LIFT ZONE AHEAD OF THE CYCLONE MAY STAY N OF THE FCST AREA ENTIRELY. BUT A BAND OF RAIN IS STILL LIKELY TO SWEEP THROUGH THE REGION WED NGT/EARLY THU AS COLD FRONT CROSSES THE RGN. ANY LINGER FREEZING PRECIPITATION SHOULD COME TO END EARLY THIS AFTERNOON. WITH SNOW AND FREEZING RAIN CONTINUING THE LONGEST IN NORTHERN WISCONSIN. MONDAY SHOULD BE MUCH NICER WITH VFR CONDITIONS AND WARMER TEMPERATURES.
307 PM EDT SUN MAR 29 2015 BRIEF HIGH PRESSURE WILL GIVE WAY TO A FRONTAL SYSTEM PUSHING SNOW AND RAIN SHOWERS INTO THE FORECAST AREA TONIGHT AND MONDAY.
INCREASING LOW LEVEL MOISTURE AND RETURN FLOW WILL KEEP TEMPERATURES A BIT WARMER MON NIGHT. FAIRLY BIG DIFFERENCES IN MODELS ON TIMING OF COLD FRONT POTENTIALLY REACHING FAR NORTHWEST SECTIONS LATE AFTERNOON. BIGGEST CONCERN THIS PERIOD IS FIRE WEATHER POTENTIAL WITH INCREASING MIXING/SURFACE GRADIENT AND WARMER TEMPERATURES. -HOWERTON BREEZY NORTHWEST WINDS WILL DEVELOP ACROSS THE AREA IN THE WAKE OF A COLD FRONT WITH SPEEDS OF 25 TO 35 MPH COMMON ACROSS CENTRAL KS. SPEEDS WILL QUICKLY DIMINISH THIS EVENING AS HIGH PRESSURE SETTLES OVERHEAD WITH CLEAR SKIES AND VARIABLE WINDS ANTICIPATED OVERNIGHT.
