WITH HIGHS ON MONDAY IN THE LOWER TO MIDDLE 40S. FURTHER RECOVERY OF LOW LEVEL THERMAL FIELDS ON ORDER OF 1-3C WARMER AT 925MB.
301 PM EDT SUN MAR 8 2015 HIGH PRESSURE REMAINED OVER THE AREA TODAY. RIDGE/VALLEY SPLIT WON'T BE QUITE AS LARGE. BUT SOME EASTERN VALLEYS COULD STILL REACH THE LOW 30S. THE DISTURBANCE WILL EXIT EARLY MONDAY LEAVING THE AREA UNDER HIGH PRESSURE ONCE MORE. A WARM FRONT WILL PUSH NORTH MONDAY NIGHT WITH ISENTROPIC ASCENT DEVELOPING AREAWIDE.
SHOULD DIMINISH THIS EVENING AS AN 850MB RIDGE AXIS CRESTS ACROSS THE REGION AND USHERS IN DRIER BOUNDARY LAYER AIR. DRY CONDITIONS AND A BRIEF WARM-UP IS FORECAST FRIDAY AS A WARM FRONT PIVOTS ACROSS WESTERN AND CENTRAL NORTH DAKOTA. FRIDAY AFTERNOON HIGHS SHOULD RANGE FROM THE LOW 30S NORTHEAST TO THE UPPER 40S SOUTHWEST.
OUR CWA IS IN THE COL BETWEEN UPPER TROUGH TO OUR SOUTH IN NEVADA/SRN CALIF AND WESTERLY FLOW IN SRN CANADA. HIGH CLOUDS DUE TO THE TROUGH NOW COVER SOUTH-CENTRAL IDAHO WITH FEWER HIGH CLOUDS ELSEWHERE. THE HIGHER CLOUDS WILL DECREASE FROM THE WEST TONIGHT AND FRIDAY AS MAIN UPPER RIDGE IN THE ERN PACIFIC BUILDS INLAND. AFTER THE TROUGH TO OUR SOUTH MOVES EAST AND AWAY FROM US THE RIDGE WILL AGAIN DOMINATE THE ENTIRE WRN U. TROUGHS IN WRN CANADA WILL FLATTEN THE RIDGE AT TIMES AND BRING CHANCES OF PCPN.
831 PM EST THU JAN 29 2015 HIGH PRESSURE EXTENDING ALONG THE EAST COAST WILL CONTINUE TO MOVE SOUTHEAST AND FARTHER OFFSHORE TONIGHT. A COLD FRONT WILL MOVE ACROSS THE REGION AFTER MIDNIGHT. EXPECT THE COLD FRONT TO PUSH THROUGH THE AREA LATER TONIGHT.
A COLD FRONT WILL BE SINKING INTO OUR NORTHERN ZONES AFTER MIDNIGHT WITH SOME COOLER AIR THERE. BUT TEMPERATURES IN THE SOUTH SHOULD STAY MOSTLY NEAR OR ABOVE FREEZING. IF SURFACE TEMPERATURES CAN DROP BELOW FREEZING. THERE WILL BE SOME POTENTIAL FOR LIGHT FREEZING RAIN.
In the wake of the departing system high pressure will build in from the northwest overnight. Winds will decrease this evening as the pressure gradient weakens near the high center. Timing of the ridge should place it directly bisecting the forecast area during early morning hours, which should strengthen the nocturnal inversion. The stronger northwest flow aloft gets shunted off to the east as the ridge builds in ahead of the system over the southwest US. High pressure retreats allowing for return flow and increase in mid to high level clouds.
/ISSUED 246 PM CST THU JAN 29 2015/ PRONOUNCED MID AND UPPER LEVEL RIDGING IS SLOWLY AMPLIFYING OVER NORTHERN MEXICO AND THE SOUTHWESTERN US. LOCALLY MODEST LOW LEVEL MOISTURE IS IN PLACE GIVING WAY TO MUCH DRIER AIR FROM 900MB AND UP WITH MODERATE SOUTHEAST WINDS DRIVEN BY NORTHEAST FLORIDA CENTERED HIGH PRESSURE. A WEAK COLD FRONT WILL APPROACH FROM THE NORTH. WIND SPEEDS WILL DIMINISH AS THE LOW LEVEL GRADIENT RELAXES AHEAD OF THE FRONT. WIND DIRECTION WILL SHIFT TO THE NORTHEAST AT ABOUT 10 TO 15 MPH AND MAX TEMPERATURES WILL BE ABOUT 10 DEGREES COOLER THAN TODAY DUE TO BOTH ADVANCING COOL AIR AND CLOUD COVER LIMITING DAYTIME HEATING. SURFACE WINDS WILL TRANSITION BACK TO THE SOUTHEAST AS TROUGHING BUILDS OVER NORTHWESTERN MEXICO.
/ISSUED 359 PM CST THU JAN 29 2015/ THE COLD FRONT CONTINUES TO MAKE GOOD PROGRESS SE ACROSS THE REGION THIS AFTERNOON. BUT THIS SHOULD CHANGE OVERNIGHT AS THE POST-FRONTAL AIR MASS DEEPENS AND IS ABLE TO OVERCOME THE HIGHER TERRAIN OF THE OUACHITAS OF SE OK/WRN AR. GIVEN THE WARMER THAN ANTICIPATED TEMPS EVEN BEHIND THE FROPA THIS AFTERNOON. AS SFC RIDGING BUILDS E INTO MS VALLEY. AS THE UPPER TROUGH W OF THE BAJA COAST BEGINS TO CLOSE OFF OVER NRN BAJA/SRN CA.
515 PM CST THU JAN 29 2015 SKIES WILL RAPIDLY CLEAR FROM WEST TO EAST LATE THIS AFTERNOON INTO THIS EVENING AS MIXING DIES AWAY AND HIGH PRESSURE BUILDS INTO THE AREA.
THE FORECAST PERIOD COMMENCES WITH THE LONGWAVE TROF OVER THE WESTERN U. WITH MOISTURE WRAPPING INTO THE NORTHEAST QUADRANT OF THE LOW PRESSURE CIRCULATION.
Gusty northwest winds will start to subside overnight and turn northerly in response to an area of high pressure which will be sliding into the region. Overnight lows will be much cooler than last night due to the colder post-frontal air mass. Despite the solar insolation expected the highs will be quite cold, although close to seasonal normals for late January.
/ISSUED 313 PM CST THU JAN 29 2015/ CLOUDS ARE INCREASING FROM NORTH TO SOUTH ACROSS THE FORECAST AREA AS A COLD FRONT CONTINUES TO MOVE THROUGH NORTH MISSISSIPPI THIS AFTERNOON. TEMPERATURES AHEAD OF THE COLD FRONT ARE IN THE 60S WHILE BEHIND THE FRONT READINGS HAVE DROPPED INTO THE 40S AND 50S. THE COLD FRONT SHOULD MOVE THROUGH THE REMAINDER OF THE FORECAST AREA BY THIS EVENING AND HIGH PRESSURE WILL START TO BUILD INTO THE REGION. DRY CONDITIONS WILL CONTINUE TONIGHT WITH LOWS FRIDAY MORNING IN THE LOW TO MID 30S. HIGH PRESSURE WILL REMAIN OVER THE CENTRAL U.
340 PM MST THU JAN 29 2015 SUNNY TO MOSTLY SUNNY SKIES PREVAIL THIS AFTERNOON WITH A BROAD AREA OF HIGH PRESSURE ANCHORED OVER THE CWA. WE WILL BE SANDWICHED IN BETWEEN THE UPPER LOW TO THE SOUTH AND A FAIRLY ACTIVE NORTHERN STREAM. SO KEPT OUR POPS ON THE LOW END EVEN IN THE MOUNTAINS. SO CONFIDENCE IS DEFINITELY HIGHER WITH LIGHT SNOW SPREADING INTO THE LOWER ELEVATIONS.
SFC RIDGING AND A DRIER AIRMASS WILL MOVE INTO MUCH OF THE REGION.
COLDER AIR WILL CONTINUE TO FUNNEL IN BEHIND A COLD FRONT TONIGHT INTO FRIDAY.
713 PM EST THU JAN 29 2015 AN ALBERTA CLIPPER/ARCTIC COLD FRONT WILL CROSS THE AREA TONIGHT.
859 PM MST Thu Jan 29 2015 An upper level ridge of high pressure extending north through the interior western US will maintain a dry NW flow aloft over the region tonight. Mid-high level clouds associated with a very weak disturbance moving east through the upper ridge should move off to the east of the region later tonight. Central Montana will remain underneath high pressure aloft through Friday and the airmass will remain dry with light surface winds.
743 PM PST THU JAN 29 2015 CLOUD COVER BECOMING MORE EXTENSIVE ACROSS THE EASTERN SIERRA AND WESTERN NEVADA THIS EVENING IN A WEAK AREA OF DEFORMATION NORTH OF THE UPPER LOW OFF BAJA.
A COLD FRONT EXTENDING FROM NORTHEAST LOUISIANA INTO CENTRAL TEXAS WILL CONTINUE TO MOVE SOUTHEAST AND ACROSS THE TAF SITES DURING THE EVENING INTO OVERNIGHT HOURS. A COLD FRONT WILL ADVANCE ACROSS THE FORECAST AREA OVERNIGHT.
938 PM CST THU JAN 29 2015 9 PM CST SURFACE ANALYSIS SHOWED A COLD FRONT WELL SOUTH OF THE MIDSOUTH. WITH A RIDGE AXIS EXTENDING SOUTHWARD INTO THE SOUTHERN PLAINS. /ISSUED 313 PM CST THU JAN 29 2015/ CLOUDS ARE INCREASING FROM NORTH TO SOUTH ACROSS THE FORECAST AREA AS A COLD FRONT CONTINUES TO MOVE THROUGH NORTH MISSISSIPPI THIS AFTERNOON. TEMPERATURES AHEAD OF THE COLD FRONT ARE IN THE 60S WHILE BEHIND THE FRONT READINGS HAVE DROPPED INTO THE 40S AND 50S. THE COLD FRONT SHOULD MOVE THROUGH THE REMAINDER OF THE FORECAST AREA BY THIS EVENING AND HIGH PRESSURE WILL START TO BUILD INTO THE REGION. DRY CONDITIONS WILL CONTINUE TONIGHT WITH LOWS FRIDAY MORNING IN THE LOW TO MID 30S. HIGH PRESSURE WILL REMAIN OVER THE CENTRAL U.
THIS LOW BROUGHT THE DRIZZLE. FREEZING DRIZZLE. THESE CLOUDS COULD HAVE AN IMPACT ON THE LOW TEMPERATURES ON FRIDAY MORNING. 12Z MODELS ARE IN GOOD AGREEMENT THAT A SHORT WAVE TROUGH WILL MOVE SOUTHEAST ACROSS NORTHERN MINNESOTA AND NORTHERN WISCONSIN.
HOWEVER WARMER H85 TEMPS EXIST TO THE WEST OVER THE DAKOTAS. THE W TO NW WINDS WERE NOT LEADING TO MUCH COOLER TEMPS IN OUR AREA. DRY CONDITIONS WILL BE SEEN ACROSS THE AREA FRIDAY NIGHT AS HIGH PRESSURE MOVES INTO THE OHIO VALLEY.
A COLD FRONT WILL MOVE INTO CENTRAL FLORIDA IN THE MORNING AND THEN MOVE THROUGH SOUTH FLORIDA IN THE AFTERNOON TO EARLY EVENING. /ISSUED 238 PM EST THU JAN 29 2015/ ANOTHER CHILLY NIGHT IS IN STORE FOR THE REGION AS HIGH PRESSURE CONTINUES TO MOVE TO THE SOUTHEAST INTO THE WESTERN ATLANTIC. HIGH PRESSURE WILL CONTINUE TO DOMINATE THE WEATHER ACROSS SOUTH FLORIDA ON FRIDAY, HOWEVER, TEMPERATURES ARE EXPECTED TO BE SLIGHTLY WARMER AS THEY WILL RISE INTO THE MID TO UPPER 70S DURING THE AFTERNOON HOURS. AT THE SAME TIME, A WEAKENING COLD FRONT WILL APPROACH THE REGION FROM THE NORTH.
859 PM EST THU JAN 29 2015 A COLD FRONT WILL CROSS THE AREA TONIGHT.
627 PM EST THU JAN 29 2015 LOW PRESSURE OVER ONTARIO WILL TRACK INTO NORTHERN NEW ENGLAND FRIDAY AS HIGH PRESSURE BUILDS EAST OVER THE SOUTHERN GREAT LAKES.
THE EVENING LOCAL SOUNDING SHOWS THAT THE WINDS IN THE LOWEST LEVELS HAVE VEERED AND ARE LIGHTER THROUGH 10000 FEET THAN 12 HOURS AGO. HIGH PRESSURE CURRENTLY CENTERED OVER NORTHERN FLORIDA IS EXPECTED TO FLATTEN E/W AND SETTLE ACROSS SOUTH FLORIDA THROUGH FRIDAY MORNING.
SUB- FREEZING TEMPERATURES ARE STILL WELL UPSTREAM AND WILL TAKE A GOOD CHUNK OF THE NIGHT TO SEE THEM GET HERE. BUT IT LOOKS LIKE SOMETIME AFTER 2 AM WE SHOULD SEE THOSE SUBFREEZING TEMPS WORKING INTO OUR AREA. A SURFACE COLD FRONT WAS ENTERING THE JKL FORECAST AREA FROM THE NW AT MID AFTERNOON. IT WILL BE FURTHER AIDED BY THE SUPPORT OF THE MID/UPPER LEVEL TROUGH AXIS PASSING OVER TONIGHT AND EARLY FRIDAY. THE LAST OF THE SNOW SHOWERS WILL TAPER OFF DURING THE DAY FRIDAY AS HIGH PRESSURE BUILDS IN AND UPSLOPE FLOW IS LOST. THIS PERIOD STARTS OUT QUIET WITH HIGH PRESSURE OVERHEAD AND TEMPERATURES NEAR 40 DEGREES.
A WEAK PRE FRONTAL TROUGH WAS ENTERING NORTHERN COUNTIES OF CWA AS OF MID EVENING WITH MAIN COLD FRONT PUSHING THROUGH SAN ANTONIO.
SOUNDINGS SUGGEST THE INVERSION CONTINUES THROUGH FRIDAY MORNING AND POTENTIALLY TRAPPING THE LOW LEVEL MOISTURE/STRATUS OVER CENTRAL IOWA DURING MUCH OF THE NIGHT. SURFACE RIDGING WILL BE ACROSS THE STATE AT THE BEGINNING OF THE LONGER TERM TOMORROW MORNING WITH FRIDAY BEING THE BEST DAY OUT OF REMAINDER OF THE FORECAST.
1043 PM EST THU JAN 29 2015 AN ALBERTA CLIPPER/ARCTIC COLD FRONT WILL CROSS THE AREA TONIGHT.
710 PM EST THU JAN 29 2015 UPDATE/AVIATION LOW PRESSURE WILL TRACK EASTWARD AWAY FROM THE REGION TONIGHT TAKING MOST OF THE PRECIPITATION WITH IT. COLD HIGH PRESSURE WILL BUILD IN FOR FRIDAY LEADING TO MAINLY DRY CONDITIONS.
910 PM CST THU JAN 29 2015 SATELLITE SHOWING THE LOW CLOUDS IN EASTERN SD SHRINKING THIS EVENING.
TEMPERATURES WILL RISE LITTLE ON FRIDAY WITH HIGHS IN THE LOWER TO MIDDLE 20S. LOWS WILL DROP OFF INTO THE TEENS LATER TONIGHT FOR MOST LOCATIONS WITH AREAS SHELTERED BY LAKE EFFECT CLOUDS DROPPING IN THE LOWER TO MIDDLE 20S.
COLD FRONT MOVING INTO THE TEXAS HILL COUNTRY AT THIS TIME WILL ENTER THE SOUTH TEXAS REGION AFTER 06Z FRIDAY. DEWPOINT TEMPS IN THE LOWER 60S ALONG THE COAST TO THE MID TO UPPER 50S OVER THE BRUSH COUNTRY AT THIS TIME. MAIN FEATURE OF SHORT TERM FORECAST IS COLD FRONT THAT MOVES THROUGH TONIGHT. EXPECT CLOUDY SKIES TOMORROW WITH TEMPERATURE MUCH COOLER. HIGHS ONLY IN THE LOWER TO MID 60S.
721 PM EST THU JAN 29 2015 TEMPERATURES THIS EVENING STILL SEVERAL DEGREES WARMER THAN 24 HOURS AGO. AS HIGH PRESSURE DOMINATES. A COLD FRONT WILL MOVE INTO CENTRAL FLORIDA IN THE MORNING AND THEN MOVE THROUGH SOUTH FLORIDA IN THE AFTERNOON TO EARLY EVENING. /ISSUED 238 PM EST THU JAN 29 2015/ ANOTHER CHILLY NIGHT IS IN STORE FOR THE REGION AS HIGH PRESSURE CONTINUES TO MOVE TO THE SOUTHEAST INTO THE WESTERN ATLANTIC. HIGH PRESSURE WILL CONTINUE TO DOMINATE THE WEATHER ACROSS SOUTH FLORIDA ON FRIDAY, HOWEVER, TEMPERATURES ARE EXPECTED TO BE SLIGHTLY WARMER AS THEY WILL RISE INTO THE MID TO UPPER 70S DURING THE AFTERNOON HOURS. AT THE SAME TIME, A WEAKENING COLD FRONT WILL APPROACH THE REGION FROM THE NORTH.
SURFACE WINDS WILL CONTINUE TO DECREASE THIS EVENING AS AN AREA OF HIGH PRESSURE AT THE SURFACE BUILDS ACROSS WESTERN KANSAS. BASED ON CLEAR SKIES, DEWPOINTS AROUND 20 AND THESE LIGHT WINDS EARLY FRIDAY MORNING EAST OF DODGE CITY WILL UNDERCUT THE COOLER GUIDANCE FOR OVERNIGHT LOWS IN NORTH CENTRAL AND SOUTH CENTRAL KANSAS. THE PREVIOUS FORECAST STILL APPEARS ON TRACK KEEPING THE COOLER HIGHS ON FRIDAY IN THE ELKHART AND LIBERAL AREAS. HIGHS ARE EXPECTED TO VARY FROM THE LOWER 40S IN EXTREME SOUTHWEST KANSAS TO NEAR 50 NEAR THE INTERSTATE 70 CORRIDOR.
AS WELL AS INCREASING UPPER LEVEL MOISTURE FROM A DEEP SW CONUS UPPER TROUGH THAT WILL REMAIN WELL SOUTH OF THE REGION. THERMAL RIDGE TIMING WITH PEAK HEATING/LACK OF SNOW COVER/AND DECENT TO STRONG INSOLATION SUPPORTS A TREND TO THE WARMER SIDE OF GUIDANCE. DIRECTING A BACKDOOR COLD FRONT INTO THE AREA SAT MORNING.
WILL SEE A LULL IN PRECIPITATION INTO THE EARLY EVENING BEFORE THE NEXT CHANCE MOVES INTO THE NORTH WITH THE NEXT SHORT WAVE AND THE ASSOCIATED COLD FRONT. BIG QUESTION IS WHETHER OR NOT THERE WILL BE ENOUGH MOISTURE AVAILABLE WHEN THE COLDER AIR MOVES IN FOR A BRIEF MIXTURE OR TURN-OVER TO SNOW ACROSS THE HIGHER ELEVATIONS OF THE NORTH. HOWEVER SURFACE TEMPERATURES SHOULD BE MOSTLY ABOVE FREEZING AND NO SIGNIFICANT ACCUMULATIONS ARE ANTICIPATED. NOTICEABLY COOLER TEMPERATURES EXPECTED FRIDAY.
/ISSUED 331 PM CST Thu Jan 29 2015/ Models are in decent agreement regarding the progression of a southern stream upper low which will dominate sensible weather across the region tonight through the upcoming weekend. Recent water vapor imagery indicates a low pressure circulation currently off the southwest California/Baja coast, which is progged to eventually cut off and slowly sink south before progressing eastward over the coming days. Thus, temperatures should remain around or above freezing for the duration, yielding a cold rain for all but the Guadalupe Mountains, northern Lea, and northwestern Eddy counties in New Mexico, where model soundings indicate probabilities for sleet to mix in with the rain mainly from late tonight through Friday.
/ISSUED 456 PM CST THU JAN 29 2015/ AN UPPER LEVEL TROUGH WILL MOVE INTO THE SOUTHWEST ON FRIDAY. WHILE MODELS HAVE TRENDED WARMER AND SOMEWHAT DRIER OVER THE PAST FEW DAYS. TEMPERATURES WILL APPROACH FREEZING AND A CHANGE OVER TO A WINTRY MIX OF RAIN/SNOW/SLEET IS POSSIBLE MAINLY WEST OF A GUYMON TO SPEARMAN TO CLARENDON LINE.
1100 PM EST THU JAN 29 2015 AN ALBERTA CLIPPER/ARCTIC COLD FRONT WILL CROSS THE AREA TONIGHT.
815 PM CST Thu Jan 29 2015 Nice cold frontal passage this morning; we got everything but cold air. Went very pessimistic on clearing of the low clouds. If the low clouds prove to be more stubborn, we will not be cold enough.
AN UPPER LEVEL LOW WAS OFF THE COAST OF BAJA CALIFORNIA WITH A GOOD AMOUNT OF MOISTURE BEING PUSHED NORTH AHEAD OF IT INTO THE SOUTHWESTERN CONUS. THE PRESSURE GRADIENT WEAKENED THROUGH THE DAY AS HIGH PRESSURE BUILT IN FROM THE WEST. WHILE THE UPPER LOW OFF THE WEST COAST MOVES INTO THE SOUTHWEST CONUS. THIS WILL ALLOW RIDGING ALOFT TO BUILD IN ACROSS THE CENTRAL PLAINS. HIGH PRESSURE AT THE SURFACE WILL MIGRATE EAST ACROSS NEBRASKA. WITH THE UPPER LEVEL LOW TO THE SOUTHWEST MIGRATING ONSHORE. WENT A BIT WARMER FOR HIGHS AS HAS BEEN THE TREND LATELY WITH THE BOUNDARY LAYER AGAIN EXPECTED TO INCUR DECENT MIXING.
713 PM EST THU JAN 29 2015 A COLD FRONT WILL CROSS THE AREA TONIGHT.
Near to slightly above normal temperatures in the lower to mid 40s are expected again tomorrow as southerly winds return but temperatures aloft remain cool.
658 PM CST THU JAN 29 2015 THE COLD FRONT WILL MOVE THROUGH SE TEXAS THIS EVENING. /ISSUED 349 PM CST THU JAN 29 2015/ COLD FRONT SLOWLY DROPPING SOUTH THROUGH THE STATE HAS PASSED WACO AND IS NEARING COLLEGE STATION. DRY TODAY WITH WEST AND NW WINDS ALLOWING TEMPS TO CLIMB TO THE LOWER TO MID 70S. ALONG THE IMMEDIATE COAST SOME POTENTIAL FOR PATCHY FOG WHERE GULF MOISTURE HAS CREPT INLAND AND AS BL SHRINKS RAPIDLY MAY GET A FEW HOURS OF LIGHT FOG BEFORE THE COLD FRONT SCOURS OUT THE MOISTURE. COOLER TOMORROW WITH 1035MB HIGH OVER OK/MO AND SETX FIRMLY IN COOL NE FLOW. FRONT PUSHES DOWN INTO RIO GRANDE VALLEY AND UPPER LOW NEARING BAJA WOBBLES SOUTHWEST INTO WESTERN MEXICO.
/ISSUED 342 AM CST THU JAN 29 2015/ (Tonight and Friday) Cold front has pushed through all of West Central Texas, and combined with increasing mid level cloudiness, to start allowing temperatures to drop a little. Air mass will continue to slowly moisten, as warm advection over the frontal boundary combines with increasing moisture moving in from the west with the approaching upper level low.
1044 PM EST THU JAN 29 2015 A COLD FRONT ALONG THE APPALACHIAN MOUNTAINS WILL MOVE ACROSS THE REGION AFTER MIDNIGHT. EXPECT THE COLD FRONT TO PUSH EAST OF THE AREA LATE TONIGHT.
AN UPPER-LEVEL TROUGH AXIS PASSING BY TO OUR NORTH IS SUPPORTING A COLD FRONT TO OUR NORTHWEST. MUCH COOLER CONDITIONS ARE EXPECTED ON FRIDAY AS HIGH PRESSURE MOVES IN BEHIND THE FRONT.
EXPECT PARTLY CLOUDY SKIES OVERNIGHT AS A DRY COLD FRONT PUSHES THROUGH THE REGION.
811 PM EST THU JAN 29 2015 THE COLD FRONT IS JUST ABOUT TO ENTER NORTHWEST GEORGIA. WILL SEE A LULL IN PRECIPITATION INTO THE EARLY EVENING BEFORE THE NEXT CHANCE MOVES INTO THE NORTH WITH THE NEXT SHORT WAVE AND THE ASSOCIATED COLD FRONT. BIG QUESTION IS WHETHER OR NOT THERE WILL BE ENOUGH MOISTURE AVAILABLE WHEN THE COLDER AIR MOVES IN FOR A BRIEF MIXTURE OR TURN-OVER TO SNOW ACROSS THE HIGHER ELEVATIONS OF THE NORTH. HOWEVER SURFACE TEMPERATURES SHOULD BE MOSTLY ABOVE FREEZING AND NO SIGNIFICANT ACCUMULATIONS ARE ANTICIPATED. NOTICEABLY COOLER TEMPERATURES EXPECTED FRIDAY.
SUBTROPICAL MOISTURE IS BEING FED INTO THE FORECAST AREA FROM THE SOUTHWEST THANKS TO AN UPPER LOW OFF OF THE COAST OF BAJA CALIFORNIA. AS THE CENTER OF THE UPPER LEVEL LOW REACHES SOCAL FRIDAY MORNING. SO AM NOT EXPECTING ANY FREEZING RAIN WITH THIS EVENT. BUT THESE SHOULD BE HIGHLY MONITORED IF COOLER AIR CHANGES THINGS.
HEADLINES WILL LIKELY BE REQUIRED OFFSHORE ON FRIDAY WITH INCREASING WINDS BEHIND THE NEXT COLD FRONTAL PASSAGE AND BUILDING SEAS LATE FRIDAY.
456 PM CST THU JAN 29 2015 AN UPPER LEVEL TROUGH WILL MOVE INTO THE SOUTHWEST ON FRIDAY. WHILE MODELS HAVE TRENDED WARMER AND SOMEWHAT DRIER OVER THE PAST FEW DAYS. TEMPERATURES WILL APPROACH FREEZING AND A CHANGE OVER TO A WINTRY MIX OF RAIN/SNOW/SLEET IS POSSIBLE MAINLY WEST OF A GUYMON TO SPEARMAN TO CLARENDON LINE.
451 PM MST THU JAN 29 2015 SUNNY TO MOSTLY SUNNY SKIES PREVAIL THIS AFTERNOON WITH A BROAD AREA OF HIGH PRESSURE ANCHORED OVER THE CWA. WE WILL BE SANDWICHED IN BETWEEN THE UPPER LOW TO THE SOUTH AND A FAIRLY ACTIVE NORTHERN STREAM. SO KEPT OUR POPS ON THE LOW END EVEN IN THE MOUNTAINS. SO CONFIDENCE IS DEFINITELY HIGHER WITH LIGHT SNOW SPREADING INTO THE LOWER ELEVATIONS.

923 PM EST THU JAN 29 2015 LOW PRESSURE OVER ONTARIO WILL TRACK INTO NORTHERN NEW ENGLAND FRIDAY AS HIGH PRESSURE BUILDS EAST OVER THE SOUTHERN GREAT LAKES.
532 PM EST THU JAN 29 2015 AN ALBERTA CLIPPER/ARCTIC COLD FRONT WILL CROSS THE AREA TONIGHT.
AS A COLD FRONT NOW REACHING FAR NW ALABAMA SWEEPS ACROSS THE AREA LATE THIS AFTERNOON AND EVENING. HIGHS THUS FAR HAVE WARMED INTO THE LOW/MID 60S. AN UPPER LEVEL LOW JUST WEST OF THE MOISTURE PLUME WILL MOVE OVER NORTHERN MEXICO OVER THE NEXT COUPLE DAYS. THE ABOVE MENTIONED COLD FRONT APPROACHING FROM THE NW WILL USHER COLDER AIR ACROSS THE FORECAST AREA.
648 PM EST THU JAN 29 2015 HIGH PRESSURE EXTENDING ALONG THE EAST COAST WILL CONTINUE TO MOVE SOUTHEAST AND FARTHER OFFSHORE THIS EVENING. A COLD FRONT WILL MOVE ACROSS THE REGION AFTER MIDNIGHT. EXPECT THE COLD FRONT TO PUSH THROUGH THE AREA LATER TONIGHT DRY.

842 AM MDT SUN MAR 29 2015 THE SHALLOW LAYER OF HUMIDITY AND DUST THAT BLEW IN LATE LAST NIGHT BEHIND A FAST MOVING COLD FRONT HAS GATHERED UP AGAINST THE FRONT RANGE FOOTHILLS EARLY THIS MORNING THE RESULT OF EAST-NORTHEASTERLY WINDS. OTHERWISE WE/RE STILL IN FOR A COOLER DAY BUT WITH THE ABUNDANT SUNSHINE. IT MAY NOT FEEL THAT MUCH COOLER. COOLER AND DRIER AIR IS MOVING IN BEHIND A COLD FRONT.
725 AM EDT SUN MAR 29 2015 A COLD FRONTAL SYSTEM WILL MOVE THROUGH THE UPPER MIDWEST AND THROUGH THE REGION LATE THIS AFTERNOON AND EVENING. LOWS SUNDAY NIGHT WILL FALL BACK INTO THE LOWER 30S. SOME CHALLENGES THIS UPCOMING WEEK INCLUDE TIMING OF SHORT WAVE TROFS AND ASSOCIATED PRECIPITATION.
