The bulk of the fog will burn off by midday (outside of some sea fog lingering right along the coast) with temperatures warming into the 80s, thanks to a building ridge aloft. A shower or two cannot be ruled out over the western portion of the forecast area (closer to the western edge of the ridge). However, the bulk of the rainfall will remain north and west of the forecast area, closer to a southward moving cold front.
1105 PM CST TUE MAR 3 2015 THE WINTRY MIX OF FREEZING DRIZZLE AND SNOW HAS MOVED OUT OF THE AREA.
RAIN CONTINUES ACROSS MUCH OF THE REGION OVERNIGHT WITH MUCH WARMER TEMPERATURES THAT HAVE RECENTLY BEEN EXPERIENCED. ALLOWING FOR A SLOW TRANSITION IN PRECIPITATION TYPE FROM RAIN TO SNOW NOW THAT A COLD FRONT HAS MOVED THROUGH THE REGION. ANY SNOWFALL ACCUMULATIONS DURING THE DAY SHOULD BE MINIMAL DUE TO ABOVE FREEZING SURFACE TEMPERATURES. ALTHOUGH THE COLDER AIR WILL MOVE IN BEHIND THE COLD FRONT.
A LENGTHY SUBTROPICAL RIDGE EXTENDS ACROSS CENTRAL FLORIDA AND WELL INTO THE GULF OF MEXICO.
AS HIGH PRESSURE CONTINUES TO SHIFT EAST OF THE AREA. THE WEATHER PATTERN CHANGES ON THURSDAY AS A WEAK COLD FRONT MOVES THROUGH THE REGION.

THESE WILL TAPER OFF THIS EVENING AS A TRANSIENT UPPER RIDGE SLIDES IN LATER TONIGHT. THE CLOUDS ARE AHEAD OF AN ELONGATED PACIFIC TROUGH THAT REACHES THE WEST COAST THURSDAY NIGHT. AN UPPER LOW DEVELOPS IN THE SOUTHERN PORTION OF THIS TROUGH AND CIRCULATES A GOODLY AMOUNT OF PACIFIC MOISTURE INTO THE DESERT SOUTHWEST. THE CLOSED UPPER LEVEL LOW IS EXPECTED TO BE SITUATED OVER BAJA CALIFORNIA ON FRIDAY MORNING AND FEEDING MOISTURE INTO THE FOUR CORNERS.
HAVE EXPANDED THE ADVISORY TO THE ENTIRE AREA AS MORE WIDESPREAD REPORTS OF FREEZING DRIZZLE HAVE STARTED TO COME IN AND CONDITIONS APPEAR TO BECOMING FAVORABLE FOR FZDZ OVER MUCH OF THE AREA. A CHECK ACROSS THE CWA INDICATES ANY FREEZING DRIZZLE IS QUITE LOCALIZED AT THIS POINT. THE LOW CLOUDS KEPT TEMPERATURES FROM REACHING THE FREEZING MARK AT MOST LOCATIONS. THE MAIN FOCUS FOR TONIGHT WILL BE THE POTENTIAL FOR FREEZING DRIZZLE AND ALSO THE CHANCE FOR SOME LIGHT SNOW OR SLEET/FREEZING RAIN. HAVE OPTED TO ISSUE A FREEZING RAIN ADVISORY FOR A PORTION OF NW WI. AND WITH THE PASSAGE OF A COLD FRONT LATER TONIGHT AND ON THURSDAY. FOCUS THEN SHIFTS TO LATER FRIDAY AFTERNOON/EVENING WITH APPROACHING S/W TROF BRINGING LIGHT SNOW TO NORTHERN MINNESOTA.
WILL NEED TO WATCH SURFACE TEMPERATURES SINCE PCPN WILL BE FALLING AS LIQUID AND IF IT DROPS BELOW FREEZING IT MAY CAUSE SOME VERY LIGHT SPOTTY ICING. WINDS WILL ALSO INCREASE LATER TONIGHT AS LOW PRESSURE AT THE SURFACE TRACKS ACROSS IOWA AND INTO NORTHEAST ILLINOIS BY DAYBREAK. THE STRONG NORTHWEST WINDS WILL BRING IN COOLER AIR FOR THURSDAY. SOUTHERLY WINDS ARE FORECAST TO INCREASE FRIDAY AS THE RIDGE MOVES EAST LATE THURSDAY NIGHT INTO FRIDAY MORNING.

A NORTH TO NORTHWEST WIND CAN BE EXPECTED BEHIND A COLD FRONT. /ISSUED 626 PM CST WED JAN 28 2015/ A COLD FRONT WILL BRING A WIND SHIFT TO ALL TERMINALS BY 10-12Z THURSDAY. AS A COLD FRONT MAKES ITS WAY SOUTHEAST ACROSS OKLAHOMA AND NORTH TEXAS.
1140 PM CST WED JAN 28 2015 LOW PRESSURE OVER EASTERN NEBRASKA WILL MOVE EAST AND PASS EAST OF THE CWA BY LATER TONIGHT. FEEL THE DRIZZLE THREAT WILL END BEFORE THE SUB- FREEZING TEMPS GET INTO THE CENTRAL COUNTIES AND DID NOT PLAY WITH ANY FREEZING PRECIP OTHER THAN THE NORTHEAST. THE CONCERN WITH THIS SYSTEM IS THE STRENGTH OF THE NORTHERN SYSTEM AND THE PHASING WITH LARGE UPPER LOW IN THE SOUTHWESTERN UNITED STATES. THIS PULLED MUCH MORE MOISTURE NORTHWARD ALONG AND INVERTED TROF AND PRODUCED A LARGE AMOUNT OF SNOWFALL ACROSS IOWA.
1242 AM CST THU JAN 29 2015 MID LEVEL S/WV TROUGH.
HIGH PRESSURE WILL CONTINUE TO MOVE EAST AND BEGIN TO DEPART THE REGION. THIS COMBINED WITH WINDS DIMINISHING THROUGH THE EVENING WILL ALLOW TEMPERATURES TO FALL INTO THE LOW TO MID 30S ACROSS INTERIOR AL COUNTIES WITH UPPER 30S AND LOW 40S ACROSS SOUTHERN MS AND NORTHWEST FL. TEMPERATURES ON THURSDAY WILL BE A FEW DEGREES WARMER THAN TODAY WITH LOW 70S ACROSS MUCH OF THE AREA AND MID TO UPPER 60S ALONG THE IMMEDIATE COASTLINE.
GIVEN THE HIGHER CLOUD DECK AND LACK OF ANY RESTRICTIONS TO VIS THINK THAT FZDZ IS LIKELY FINISHED AT THOSE LOCATIONS. LOW PRESSURE JUST WEST OF KENORA AT MID AFTERNOON MOVING EAST. LOW LEVEL MOISTURE LOOKS TO REMAIN IN PLACE TONIGHT WITH BUFKIT SOUNDINGS SHOWING THE POTENTIAL FOR SOME PATCHY FREEZING DRIZZLE/FLURRIES IF ANY PRECIP FALLS. HIGH PRESSURE AND DRIER COLDER AIRMASS MOVING IN SHOULD ALLOW FOR SOME CLEARING. NEXT SYSTEM TO MOVE EAST-SOUTHEAST THROUGH SOUTHERN CANADA FRIDAY WITH WARMER AIR AND SOUTH WINDS FRIDAY.
352 AM CST Thu Jan 29 2015 (Today and Tonight) A cold front will move south across West Central Texas today.
