HIGH PRESSURE ACROSS AREA WILL RESULT IN DRY LOW TO MID LVL AIR. /ISSUED 455 AM CST SUN JAN 17 2016/ SKIES HAVE CLEARED ACROSS ALL OUR TERMINAL LOCATIONS THIS MORNING IN THE WAKE OF A UPPER LEVEL TROUGH THAT PASSED THROUGH THE REGION LAST NIGHT. SFC RIDGING CENTERED ACROSS NE TX INTO CENTRAL TX WILL CONTINUE TO MOVE EASTWARD INTO THE REGION TODAY RESULTING IN MOSTLY LIGHT AND VARIABLE WINDS. THIS TROUGH WILL MOVE INTO THE LOWER MISS VALLEY OVERNIGHT AND COULD BE ACCOMPANIED BY SOME AC NEAR 10-12KFT AFTER DARK THIS EVENING.
Strong cold front is ahead of schedule and is located across far nern OK at this time. /ISSUED 401 AM CST SUN JAN 17 2016/ Canadian cold front will enter northeast Oklahoma within the next couple hours and will sweep south across the area today.
356 PM CST SUN JAN 17 2016 UPSTREAM UPPER TROF EVIDENT IN WATER VAPOR SATELLITE IMAGERY NEARING THE TX PANHANDLE PROGGED TO CONTINUE TRANSLATING SE AND PASS THROUGH THE REGION RELATIVELY HARMLESSLY TOMORROW. WITH LOWS TONIGHT EXPECTED TO FALL INTO THE LOW/MID 30S AMID GOOD RADIATIONAL COOLING.
AIR MASS STILL REMAINS COLD WITH THE LOWER LEVELS STILL NEAR THE DENDRITIC ZONE. SO BROADENED THE AREA COVERED BY PATCHY FREEZING FOG THAT OVERNIGHT SHIFT HAD PUT IN THERE. STILL THINK THE LATEST GUIDANCE IS STILL TOO WARM AND TRENDED TEMPERATURES DOWN TOWARD THE COOLER GUIDANCE THAT PERFORMED BETTER TODAY. ABOVE MENTIONED FREEZING FOG WILL LAST THROUGH MID MORNING. ALSO DUE TO THE DEVELOPING/STRENGTHENING LEE TROUGH OUR SURFACE WINDS START BACKING TO A SOUTH TO SOUTH SOUTHEAST WIND DIRECTION BEGINNING LATE IN THE MORNING.
COOLER THAN NORMAL THROUGH MID WEEK. LARGE AREA OF HIGH PRESSURE WILL NOSE INTO THE STATE BEHIND RAPIDLY DEPARTING FRONTAL TROUGH. GRADUALLY DECREASING NORTHWEST TO NORTH WINDS WILL USHER IN MUCH COOLER/DRIER AIR. WITH HIGH TEMPS IN THE LOWER TO MID 60S. CONDITIONS EXPECTED TO REMAIN COOLER AND MOSTLY DRY MON-WED BEFORE A WARMING TREND FINALLY ON THU. A DEEP BUT PROGRESSIVE TROUGH MOVES THROUGH THE CTRL-ERN CONUS FRI-SAT AND OFFSHORE INTO THE ATLC SAT NIGHT-SUN.
WITH AN UPPER LOW DROPPING ACROSS THE AREA TODAY AND TONIGHT WE SHOULD GET SOME CLOUDS TO FORM IN ADDITION TO THE LAKE EFFECT CLOUDINESS.
ANOTHER COLD FRONT BLAST THROUGH LATE TONIGHT WITH A BRIEF PERIOD OF CLOUDS JUST BEHIND THE FRONT. A COLD FRONT WILL APPROACH FROM THE NORTH OVERNIGHT AND HAVE INTRODUCED SOME MVFR CEILINGS FOR A BRIEF PERIOD AROUND 12Z. 75 DRIER CONDITIONS WILL RETURN DURING THE DAY TODAY AS THE LOW PRESSURE SYSTEM PUSHES OFF TO THE EAST.
MAINLY LIGHT SNOW SHOULD CONTINUE INTO THE EVENING WITH THE APPROACH AND PASSAGE OF A COLD FRONT. WITH TERRAIN ENHANCED SNOW IN THE RIDGES. AN UPPER LOW/TROF IS PROGGED TO TRACK ACRS ONTARIO INTO THE NE CONUS MON AND TUE. SNOW SHOWERS SHOULD TAPER OFF TUE WITH BUILDING HIGH PRESSURE.

/ISSUED 1129 AM CST SUN JAN 17 2016/ ARCTIC COLD FRONT IS PUSHING INTO NORTHEAST ARKANSAS AND THE MISSOURI BOOTHEEL AT THIS TIME. BUT MOST OF THE REGION SHOULD WARM INTO THE LOW TO MIDDLE 40S. A WEAKENING MIDLEVEL DISTURBANCE AND SURFACE COLD FRONT WILL APPROACH THE MIDSOUTH. DEW POINTS BEHIND THE COLD FRONT TONIGHT ARE EXPECTED TO DIP INTO THE SINGLE DIGITS AS FAR SOUTH AS NORTH MISSISSIPPI. MORNING LOWS WILL RANGE FROM THE LOWER TEENS TO MIDDLE 20S MONDAY MORNING.
will gradually trend upward into the VFR range with time behind the arctic cold front. Strong cold front is ahead of schedule and is located across far nern OK at this time. /ISSUED 401 AM CST SUN JAN 17 2016/ Canadian cold front will enter northeast Oklahoma within the next couple hours and will sweep south across the area today.
1129 AM CST SUN JAN 17 2016 A COLD FRONT MOVING INTO THE REGION THIS AFTERNOON WILL SHIFT WINDS TO THE NORTH AND BRING IN LOW CIGS AND VISBYS. WHILE CONCURRENTLY A BREEZY COLD FRONT MOVES ACROSS THE FA /15-20 MPH/. SOUNDINGS INDICATE MOISTENING IN THE LOW LEVELS WHICH RAISES CONCERN FOR THE DEVELOPMENT OF A STRATUS DECK AND/OR FOG. A SLIGHT UPTICK IN 500 MB TEMPS SUGGESTS IT WILL BE A FEW DEGREES WARMER THAN YESTERDAY /40S AND 50S/. AS THE COLD FRONT IS NOT USHERING IN AN OVERLY COLD AIRMASS. A SERIES OF UPPER LEVEL SHORT WAVE TROUGHS WILL HAVE LITTLE MOISTURE TO WORK. WITH THE SERIES OF UPPER WAVES WILL BE A SERIES OF RELATIVELY WEAK COLD FRONTS.
HIGH PRESSURE BEGINS BUILDING INTO THE REGION MONDAY MORNING AND KEEP THINGS DRY THROUGH THE SHORT TERM.
TEMPERATURES ARE A FEW DEGREES WARMER THAN THIS TIME YESTERDAY DUE TO WARM AIR AHEAD OF THE LOW PRESSURE SYSTEM CURRENTLY BRINGING PRECIPITATION OVER NORTHERN CALIFORNIA.
BUT THE 5 TO 15 MPH WIND SPEEDS WILL SOMEWHAT COUNTERACT IT DUE TO THE LOW LEVEL MIXING. SOME AREAS OF ALONG THE HIGHER TERRAIN FROM THE TWIN PORTS INTO THE ARROWHEAD COULD SEE WIND CHILLS BRIEFLY APPROACH 45 BELOW ZERO EARLY SUNDAY. MONDAY WILL BE WARMER THAN TODAY. WITH HIGHS REACHING TO AROUND 0 DEGREES THANKS TO OVERALL WARMER AIRMASS AND MOSTLY SUNNY SKIES.

THIS COLD FRONT IS EXPECTED TO MAKE STEADY PROGRESS NORTHEAST TO SOUTHWEST ACROSS THE PANHANDLES TODAY. LOW CLOUDS ARE EXPECTED TO FILTER IN BEHIND THE COLD FRONT AND THEN AREAS OF FREEZING FOG SHOULD DEVELOP OVERNIGHT ACROSS MUCH OF THE REGION. THERE IS SOME HINT THAT SOME LIGHT FREEZING DRIZZLE COULD FORM AS WELL. A LEE-SIDE TROUGH DEVELOPS AND DOWNSLOPE WINDS WILL PREVAIL.
THIS MOISTURE WILL FINALLY BE PUSHED OUT OF THE AREA AS THE ARCTIC COLD FRONT NOW POSITIONED OVER CENTRAL KY AND SLOWLY PUSHING SOUTHEAST. THE HIGH RATIOS WITH THE ARCTIC AIR MOVING THROUGH WILL AT LEAST PRODUCE A TENTH TO A COUPLE TENTHS OF SNOWFALL BUT MAINLY ALONG AND NORTH OF THE MOUNTAIN PARKWAY AS WELL AS THE HIGHER TERRAIN TO THE EAST.
FORECASTS WERE UPDATED THIS MORNING TO REMOVE THE HIGHER COVERAGE OF SHOWERS AND ISOLATED THUNDERSTORMS. COLD FRONT EXPECTED TO PASS THROUGH THE KEYS THIS AFTERNOON WILL CAUSE THE STRONG WEST WINDS TO BECOME NORTHWEST AND BEGIN DECREASE SLIGHTLY. WHILE WINDS WILL TURN NORTHWEST UPON PASSAGE OF THE COLD FRONT THIS AFTERNOON AND SETTLE CLOSER TO 20 KNOTS TONIGHT.
RESIDUAL LIGHT RAIN IS RAPTLY MOVING E/NE ACROSS COASTAL NE FL AND SE GA AS LOW PRESSURE EJECTS TO THE NE. WITH READINGS MAINLY IN THE LOWER/MID 50S.

252 PM CST SUN JAN 17 2016 A bitterly cold airmass continues to stream southward into central Illinois, courtesy of a 1032mb Canadian high pressure building into the central/northern Plains. High pressure will dominate the region tomorrow with very cold air sitting over the area through tomorrow night. As this high pressure ridge shifts to the east, so will the very cold air. ECMWF and Canadian are furthest south, while the GFS is little quicker and north with the track of the low. The low pressure will track from Ark into TN and with this track it should keep most of the pcpn south of the CWA through the period. VFR conditions will prevail through the entire 18z TAF period as strong Canadian high pressure builds into the region.
WHILE A LOW PRESSURE SYSTEM TRACKS OFF THE SOUTHEAST UNITED STATES COAST. AN ARCTIC COLD FRONT WILL MOVE THROUGH THE REGION TONIGHT AND INTO MONDAY. THESE AREAS WILL FOR A COUPLE MORE HOURS BE IN THE MAXIMIZED OVERLAP OF THE HIGHER PRECIPITATION RATES AND AMOUNTS. AND ASSOCIATED BOUNDARY LAYER COOLING VIA MELTING -TO THE FREEZING MARK- BEFORE PRECIPITATION ENDS FROM WEST TO EAST THROUGH EARLY THIS AFTERNOON.
WE WILL KEEP THE WIND CHILL WARNING UNTIL 18Z AND TRANSITION TO THE WIND CHILL ADVISORY WITH WINDS A BIT LIGHTER AS HIGH PRESSURE SLOWLY BUILDS IN BY TONIGHT. AND IT IS CURRENTLY CLEAR IN CANADA UNDER THIS HIGH. IT WILL BE DRY WITH SUNSHINE AS HIGH PRESSURE DRIFTS SLOWLY EAST BY AFTERNOON.
418 PM EST SUN JAN 17 2016 A COLD FRONT WILL MOVE EAST TONIGHT.
THE LOW PRESSURE SYSTEM THAT RAPIDLY MOVED THROUGH THE AREA IS NOW LOCATED OFF THE CAROLINA COASTLINE. BREEZY NORTH NORTHWEST WINDS CAN BE EXPECTED AS THE GRADIENT TIGHTENS BETWEEN THE FRONTAL BOUNDARY AND STRONG HIGH PRESSURE BEGINNING TO RIDGE OVER THE AREA.
THE LOWER AND MID LVLS REMAIN DRY WITH DEWPOINTS IN THE MID 20S TO NEAR 30. A COLD FRONT TO THE NORTH.
EXPECT SUNNY SKIES TODAY AS HIGH PRESSURE MOVES INTO THE REGION. RANGING FROM THE MID 40S NORTH TO THE LOW 50S SOUTH. AN ARCTIC COLD FRONT WILL MOVE INTO NORTHERN PORTIONS OF THE FORECAST AREA EARLY MONDAY AND BE ACCOMPANIED BY MID AND HIGH LEVEL CLOUDS BUT NO PCPN AND NO CIGS BELOW 3KFT ARE ANTICIPATED. A BROAD UPPER LEVEL LONGWAVE TROUGH OVER THE CENTRAL/EASTERN CONUS IS STEERING AN ARCTIC AIRMASS SOUTHWARD WITH THE LEADING EDGE NOW PUSHING INTO THE MID MS VALLEY.
A MID TO UPPER-LEVEL LOW OVER THE UPPER GREAT LAKES WILL CONTINUE EAST-SOUTHEAST IN RESPONSE TO THE EASTWARD PROGRESSION OF AN AMPLIFYING UPSTREAM RIDGE MOVING THROUGH THE INTERIOR WEST.
319 PM EST SUN JAN 17 2016 COLD FRONT HAS PUSHED THROUGH THE FLORIDA KEYS. BUT THE FORECAST IS HENCEFORTH DRY THE MOST SIGNIFICANT FACTOR COOLER TEMPERATURES TO NEAR 60 AND EVEN IN THE UPPER 50S BY MONDAY NIGHT. HIGH PRESSURE WILL DOMINATE THE FLORIDA KEYS WEATHER WITH MOSTLY FAIR WEATHER AND MODERATE TO BREEZY CONDITIONS.
THE COLD FRONT THAT WAS NEAR AN ALTUS TO ADA LINE AT 230 PM WILL CONTINUE TO PUSH SOUTH. THUS GENERALLY WENT TOWARDS THE SLIGHTLY WARMER SIDE OF GUIDANCE LOWS THINKING CLOUD COVER WILL BE SLOW TO ERODE.
WITH SLIGHTLY WARMER TEMPERATURES IN OUR SOUTH CENTRAL SD ZONES.

COLD TEMPS AND WINDS SHOULD RESULT IN ADVISORY LVL WIND CHILLS IN THE RIDGES TONIGHT ALSO. AN UPPER LOW/TROF IS PROGGED TO TRACK ACRS ONTARIO INTO THE NE CONUS MON AND TUE. SNOW SHOWERS SHOULD TAPER OFF TUE WITH BUILDING HIGH PRESSURE. ADVISORY LVL WIND CHILLS ARE EXPD TO CONTINUE ACRS THE HIGHER TERRAIN AREAS THRU TUE MRNG.
ALTHOUGH LIGHT WINDS SHOULD KEEP WIND CHILLS WARMER THAN ADVISORY CRITERIA VALUES.
Strong arctic cold front continues to progress SW across SW KS this morning, with areas of freezing fog developing immediately after frontal passage. Just issued a nowcast to cover, and placed areas of freezing fog in the grids, but will not issue an advisory at this time. There may be some patchy freezing fog Monday morning as weak warm air advection resumes. Forecast soundings are supportive of patchy freezing fog, but there is drier air forecast to the east, so think overall it will be more limited than compared to a widespread freezing fog event.
922 AM PST SUN JAN 17 2016 DRY AND A LITTLE WARMER TODAY WITH TEMPERATURES REACHING THE LOW SEVENTIES IN PORTIONS OF THE INLAND VALLEYS.
1048 AM CST SUN JAN 17 2016 THE ARCTIC COLD FRONT WAS ROUGHLY ALONG I-40 AT 1030 THIS MORNING. WE UPDATED THE TEXT PRODUCTS EARLIER TO REMOVE THE FREEZING FOG WORDING. MVFR CONDITIONS WILL SPREAD OVER REGION EARLY IN FORECAST PERIOD AS ARCTIC COLD FRONT SURGES QUICKLY SOUTH. AND IFR/LIFR CONDITIONS POSSIBLE FIRST 3 TO 4 HOURS OF FORECAST AT KLAW WHERE FREEZING FOG HAS DEVELOPED AHEAD OF HIGH CLOUDS. SOME DENSE FREEZING FOG WILL BE POSSIBLE WHERE HEAVIEST PRECIP FELL YESTERDAY. ARCTIC COLD FRONT WILL BE ARRIVING NORTHERN OKLAHOMA BEFORE DAYBREAK SO THERE WILL LIKELY BE LITTLE IN THE WAY OF TEMPERATURE RECOVERY THROUGH THE DAY OVER NORTHERN ONE-QUARTER OR SO OF OKLAHOMA WITH TEMPERATURES FALLING MOST AREAS THROUGH THE AFTERNOON.
A cold front will arrive this evening, briefly shifting winds to the north. /issued 322 AM CST SUN JAN 17 2016/ This week will be the definition of zonal upper level flow with a series of troughs moving across the area in modest westerly flow. These troughs will bring us weak cold fronts, about one every day, that will do little other than shift the wind direction and keep temperatures from rising too far above normal. About the only hazards to keep an eye on this week will be the potential for strong winds in the Guadalupe Mountains associated with the base of the upper troughs, and possible fire weather concerns with dry air in place though light winds in the lower elevations will limit the critical fire weather potential.
OVER THE NEXT 24 HOURS A 1032MB HIGH PRESSURE SYSTEM WILL BUILD OVERHEAD.
COLD FRONT IS PUSHING QUICKLY SE ACROSS ORLANDO METRO AT THIS TIME. MUCH COOLER AIR ADVECTS INTO THE REGION UNDER CLEAR TO MOSTLY CLEAR SKIES. LOWS MAINLY IN THE LOW TO MID 40S EXCEPT LOW 50S MARTIN COAST. WINDS SHIFTING OUT OF THE NW AS COLD FRONT SWEEPS ACROSS THE TERMINALS FROM NW-SE.

TODAY THROUGH MONDAY NIGHT GUIDANCE IN BETTER AGREEMENT THIS MORNING WITH COLD FRONT MOVING INTO THE STATE TODAY AND TONIGHT. AND ELEVATED ROADWAYS LIKE BRIDGES AND OVERPASSES ACROSS THE NORTH. HIGH PRESSURE WILL SETTLE ACROSS THE AREA MONDAY AND MONDAY NIGHT.
AN ARCTIC COLD FRONT WILL APPROACH FROM THE NORTHWEST AND PLUNGE ACROSS CENTRAL NC LATE TONIGHT INTO EARLY MONDAY.
This system is considerably warmer than yesterday so most of the snow accumulation is expected to occur over the mountains and near the Cascade Crest. A few morning updates to fine tune snow levels along the Highway 97 corridor and into portions of southern Grant County. Snowfall amounts remain a challenge with the potential for 1-2 inches in the lowest elevations. Heavier accumulations on the order of 3-5 inches will impact travel into the higher elevations and across the Cascade Passes. Latest radar and satellite data was showing precipitation from the next warm front moving toward the Cascades. The precipitation threat will taper off over the western sites overnight, however confidence is high that the low clouds and IFR conditions will persist.
335 PM CST SUN JAN 17 2016 AN ARCTIC COLD FRONT WHICH MOVED THROUGH THE PANHANDLES TODAY HAS RESULTED IN STRONG COLD AIR ADVECTION IN ITS WAKE. THE SHALLOW COLD AIR HAS ALSO RESULTED IN CONSIDERABLE LOW CLOUDINESS ALONG WITH PATCHY OR AREAS OF FREEZING FOG ACROSS MUCH OF THE FORECAST AREA. HI- RES MODELS AND LOW-RES MODELS HAVING A DIFFICULT TIME WITH THE FREEZING FOG WHICH MAY BE DUE TO THE SHALLOWNESS OF THE COLD AIR MASS. HOISTED A FREEZING FOG ADVISORY THIS AFTERNOON THROUGH TONIGHT WHICH EXPIRES AT 16Z MONDAY. FREEZING FOG ADVISORY MAY NEED TO BE EXPANDED IN AREA AND MAY NEED TO BE CANCELLED EARLY SHOULD THE FOG AND LOW CLOUDS LIFT LATER THIS EVENING OR LATE TONIGHT OR BY MONDAY MORNING.

ANOTHER COLD FRONT FROM THE GREAT LAKES THROUGH CENTRAL KANSAS AND THEN A STATIONARY BOUNDARY ALONG THE FRONT RANGE OF THE COLORADO ROCKIES INTO IDAHO. 850MB TEMPERATURES TO MODERATE THROUGH THE DAY AS RIDGE TO THE WEST PUSHES EAST. A WARM FRONT WILL BEGIN TO MOVE NORTHEAST FROM KANSAS AND NORTHEAST COLORADO MONDAY.
CLOSER TO HOME WINDS ASSOCIATED WITH THE LOW REMAIN SLIGHTLY ELEVATED ACROSS THE AREA ESPECIALLY ACROSS THE COASTAL WATERS. HIGHS WILL BE IN THE LOW TO MID 50S TODAY AND MONDAY. OVERNIGHT TONIGHT AND MONDAY NIGHT LOWS WILL DIP DOWN TO THE FREEZING MARK OR LOWER FOR PORTIONS OF THE NORTHSHORE. LOCATIONS ON THE SOUTHSHORE ARE NOT EXPECTED TO SEE FREEZING TEMPERATURES EITHER NIGHT.
CLOUD COVER ALONG THE EASTERN EDGE OF THIS RIDGE THIS MORNING MAY IMPACT PORTIONS OF THE WESTERN FORECAST AREA BY MONDAY MORNING. LOWS TONIGHT STILL LIKELY TO DROP INTO THE LOWER TO MID TEENS BELOW ZERO.
