134 PM EDT THU MAR 12 2015 HIGH PRESSURE BUILDING INTO THE NORTH COUNTRY WILL PROVIDE COLD AND BLUSTERY CONDITIONS TODAY WITH HIGHS ONLY TOPPING OUT IN THE 20S. AS THE HIGH DRIFTS OVERHEAD TONIGHT, WINDS WILL ABATE BUT BELOW NORMAL TEMPERATURES WILL CONTINUE. AS DRIER AIR AND A RIDGE OF HIGH PRESSURE BUILDS INTO THE REGION. HIGH PRESSURE CENTERS OVER THE NORTH COUNTRY TONIGHT WITH SKIES INITIALLY CLEARING THIS EVENING AND WINDS TRENDING LIGHT. FOR FRIDAY, HIGH PRESSURE DRIFTS EAST OF THE CWA WITH SOUTHERLY RETURN FLOW DEVELOPING AND MODERATING TEMPS BACK TOWARDS SEASONAL NORMALS IN THE 30S.
The rain will develop as a result of a deep moisture plume being directed into the region on the eastern periphery of an upper level trough across the southern Plains. Expect an increase in rainfall rates heading into the afternoon and evening as embedded short wave trough now in the western Gulf pushes north toward southern Missouri.
A GOOD 15-20 DEGREES COOLER THAN TODAY. AGAIN 15-20 DEGREES COOLER THAN TODAY. SOUTHERN STREAM UPPER LOW OVER WESTERN MEXICO STILL PROGGED TO CUTOFF AND RETROGRADE TO SRN TIP OF BAJA CALIFORNIA THRU MON. THIS LEAVES SHORT WAVE TROUGH ZIPPING SE THRU UPPER MIDWEST AND NORTHEAST CONUS THIS WEEKEND AS PRIMARY DRIVER OF SENSIBLE WEATHER OVER THE AREA. MOIST PLUME AND WEAK WARM/MOIST ADVECTION SHOULD STRETCH OUT OVER GULF COAST AND SRN GA 00Z SUN WITH COLD FRONT ASSOCD WITH MIDWEST SHORT WAVE MOVING INTO TN VALLEY.

THINK THAT AT LEAST THE NORTHERN CWA WILL GET BELOW FREEZING AGAIN OVERNIGHT.
338 PM CDT Thu Mar 12 2015 Well defined upper trough on water vapor continues to lift northward from the Red River. Lows tonight will range from the lower 40s with mostly clear skies in the north central to the middle 40s southeast corner where a combination of higher dewpoints and more clouds will help to keep temps up a bit. Highs there will be in the middle to upper 60s with readings in the lower 70s along and north of the i 70 corridor.
LOW PRESSURE FORMING OVER THE GULF OF MEXICO TODAY WILL LIFT SLOWLY NORTHWARD THROUGH LA/AR TONIGHT/FRIDAY. SOUTHERLY MID LVL FLOW FETCH DIRECTLY OUT OF THE GULF OF MEXICO WILL FEED PLENTY OF DEEP MOISTURE INTO THE SYSTEM FOR AN EXTENDED TIME LATE THIS WEEK DUE TO THE COMBINATION OF A BLOCKING RIDGE OF HIGH PRESSURE OVER THE SE U. AND A STAGNANT TROF OUT OVER THE PLAINS.
A COLD FRONT WILL COME THROUGH ON FRIDAY NIGHT ALTHOUGH LITTLE OR NO PRECIPITATION IS EXPECTED WITH THIS SYSTEM.

WITH THE HIGHEST ACCUMULATIONS OVER THE SAN JUAN MOUNTAINS. AN UPPER RIDGE OVER THE WESTERN EDGE OF THE CONUS. WILL LEAN OVER TO THE NORTHEAST ABOVE OUR SPLITTING LOW PRESSURE TROUGH BY FRIDAY AFTERNOON. NIGHTTIME LOWS WILL BE COOLER FRI NIGHT.
SE OK AND NW AR SITES WILL SEE THE HIGHEST RAIN CHANCES DURING THE PERIOD.
A WEAK COLD FRONT WILL SLOWLY MOVE ACROSS THE AREA OVERNIGHT BUT NO PRECIPITATION OR EVEN LOW CLOUDS ARE EXPECTED WITH THE FRONT. SLIGHTLY WARMER ACROSS THE EAST WHERE THE STRONGER WINDS WILL CONTINUE FOR THE BETTER PORTION OF THE NIGHT.
THIS EVENING THROUGH FRIDAY NIGHT 21Z SURFACE ANALYSIS SHOWS LOW PRESSURE OVER NORTH DAKOTA WITH A TROUGH EXTENDING SOUTHWARD INTO EASTERN SOUTH DAKOTA AND CENTRAL NEBRASKA. GUSTY NORTHWEST WINDS HAVE DEVELOPED IN THE RELATIVELY TIGHT SFC PRESS GRAD TO THE WEST OF THE TROUGH OVER NORTHEASTERN WYOMING AND WESTERN SOUTH DAKOTA. AN UPPER RIDGE WILL BUILD OVER THE AREA FROM THE WEST ON FRIDAY CREATING SUNNY SKIES.
The cold front has pushed east of the region, allowing cooler and drier air to work in. Convection continues to fire ahead of the cold front and main convective line. The overall picture is becoming more complicated as the cold front is surging eastward into convection that is on a slow northeast track. The cold front should clear the area shortly after sunrise pushing convection well east of the area. Friday night and Saturday will be dry with high pressure in place.
MILD SOUTHWEST FLOW TODAY AHEAD OF A FAST MOVING SHORT WAVE TROUGH.

THIS SHOULD LIMIT ANY NWD EXPANSION OF THE CONVECTION CURRENTLY OVER SE TX SPREADING E TOWARDS THE LOWER SABINE RIVER. WE SHOULD SEE THE HIGH CLOUDS TO BEGIN TO THIN LATE IN THE DAY ACROSS THE NRN ZONES. SHOULD SEE A REFRESHING CHANGE IN THE LOWER TEMPS AND HUMIDITES THIS AFTERNOON.
EXPECT THE FOG TO BEGIN TO DISSIPATE THROUGH THE MORNING BUT IT WILL BE SLOW TO DO SO AS IT WILL BE ENCOMBERED BY THE LOW LEVEL CLOUD DECK A FEW HUNDRED FEET ABOVE IT. THE MAIN CONCERN TODAY WILL BE THE COLD FRONT WHICH IS JUST BEGINNING TO NUDGE ITS WAY INTO SOUTHEAST TEXAS AND CENTRAL LOUISIANA THIS MORNING. /ISSUED 439 AM CDT FRI APR 10 2015/ THIS MORNING THE COLD FRONT WAS LOCATED ACROSS NORTHERN LOUISIANA INTO THE LAKES REGION OF LOUISIANA. RETURN FLOW SETS UP ON SATURDAY AND THE FRONT WILL BEGIN TO RE-TREAT BACK AS A WARM FRONT.
