THE UPPER LEVEL RIDGE REMAINS IN PLACE AND THIS FEATURE WILL DOMINATE THE WEATHER PATTERN TODAY AND INTO THE WEEKEND. /ISSUED 336 AM CDT TUE JUL 21 2015/ CURRENT ANALYSIS CONTINUES TO INDICATE THAT HIGH PRESSURE CONTINUES TO DOMINATE THE WEATHER PATTERN ACROSS THE AREA. THE MOISTURE LOCATED ACROSS THE NORTHERN GULF COAST WILL CONTINUE TO SPREAD WEST JUST A BIT ON THE SOUTHERN PERIPHERY OF THE RIDGE. RIDGE BECOMES MORE ROBUST TOWARDS THE END OF THE WEEK CAUSING RAIN CHANCES TO GO DOWN AND TEMPERATURES TO CLIMB ONCE AGAIN. BUT OVERALL TRENDS IN THE GUIDANCE MAINTAINS THE RIDGE OVER THE AREA WITH SOME POSSIBLE WEAKENING LATE AS TROUGH DEEPENS ALONG THE EAST COAST.
MORE SHOWERS AND THUNDERSTORMS ARE LIKELY TO DEVELOP OVER THE MOUNTAINS THIS AFTERNOON WITH A SLIGHT CHANCE OVER THE LOWER ELEVATIONS.
THE MID LEVEL RIDGE WILL SLOWLY BUILD INTO THE REGION FROM THE SE. TEMPS WILL WARM THROUGH THE PERIOD AS WELL AS THE RIDGE TAKES HOLD AND THE GROUND SLOWLY DRIES FROM RECENT STORMS.
SEVERAL DIFFUSE BOUNDARIES ARE EVIDENT ACROSS THE REGION ALONG WITH THE WEAK SFC FRONT/TROUGH EXTENDING ACROSS SRN OK/TEXOMA. BUT ADDITIONAL DEVELOPMENT IS EXPECTED THIS AFTERNOON AND TONIGHT WITH THE HIGHEST CHANCES IN THE NORTH. A SURFACE COLD FRONT AND THE PRECIPITATION/CLOUDS NORTH WILL KEEP TEMPERATURES MUCH LESS THAN RECENT DAYS ACROSS THE NORTH.
MOISTURE POOLING AHEAD OF THIS BOUNDARY SHOULD KEEP DEWPOINTS IN THE LOWER 70S DESPITE SOME DRIER AIR ALOFT. CLOUDS WILL INCREASE THRU THE MORNING AS WEAK COLD FRONT APPROACHES THE REGION. MID/HIGH LEVEL CLOUDS WILL INCREASE AS A WAVE OF LOW PRESSURE DEVELOPS ALONG PORTION OF STALLED FRONT TO THE WEST OF THE REGION.
A STRONG ONSHORE FLOW AND A DRY COLD FRONT BROUGHT GUSTY WINDS YESTERDAY. AN UPPER LEVEL TROUGH OFFSHORE WILL SHIFT EASTWARD OVER THE NEXT 24 HOURS. THE APPROACH OF THE UPPER LEVEL TROUGH SHIFT SUPPRESS ANY CONVECTION TO SOUTHEAST OREGON TODAY. RED FLAG WARNINGS ARE IN EFFECT THROUGHOUT THE LOWER COLUMBIA BASIN AND SURROUNDING VALLEYS TODAY DUE TO WINDS AND LOW RELATIVE HUMIDITY.
850 AM MST TUE JUL 21 2015 A DRIER SOUTHWESTERLY FLOW OVER THE REGION WILL BRING ONLY A FEW MOUNTAIN SHOWERS AND THUNDERSTORMS EACH DAY ACROSS THE HIGHER TERRAIN OF SOUTH-CENTRAL ARIZONA THIS WEEK. TEMPERATURES WILL REMAIN HOT THROUGH THE WEEK WITH HIGHS APPROACHING THE 110 DEGREE MARK FOR SOME LOCALES ON THE LOWER DESERTS BY THE WEEKEND. ONCE AGAIN INCREASING THE THREAT OF ISOLATED THUNDERSTORMS OVER THE LOWER DESERTS. WEAK TROFFING ALONG THE CA COAST HAS SET UP A DRYING SOUTHWESTERLY FLOW ALOFT ACROSS THE REGION THIS MORNING. LATEST SPC MESOANALYSIS GRAPHIC SHOWED MLCAPE DOWN WELL BELOW 500 J/KG OVER THE LOWER DESERTS.
THIS NEW DEVELOPMENT IS IN THE VICINITY OF THE MORNING LOW LEVEL JET AND SURFACE TROF SO IT MAY PERSIST UNTIL SURFACE INVERSION BREAKS MID MORNING. SOUTHWEST FLOW WILL STRENGTHEN OVER TIME ACROSS THE AREA AS BROAD UPPER TROF ALONG THE WEST COAST SLOWLY WORKS EASTWARD. MOST OF THE STRONGER ENERGY ASSOCIATED WITH THE TROF WILL MISS THE FORECAST AREA TO THE WEST AND NORTH. PRECIPITATION CHANCES WILL BE A BIT BETTER ON WEDNESDAY COMPARED TO TODAY BASED ON THE PROXIMITY OF THE WESTERN TROF. HI-RES ENSEMBLE MODELS ALSO SHOWING THE POTENTIAL FOR A FEW STORMS TO DEVELOP MID AFTERNOON OVER SOUTHEAST MONTANA AND NORTHEAST WYOMING IN THE VICINITY OF A SURFACE TROF AND THE BLACK HILLS. WITH THE SOUTHWEST FLOW EXPECT WARMER TEMPERATURES WITH LOWER 90S LOOKING REASONABLE FOR MOST LOW ELEVATION LOCATIONS TODAY AND WEDNESDAY.
Cooler but drier and locally breezy conditions are expected across the Inland Northwest for today. An upper level trough will gradually dig into the region through Wednesday. A dry slot coming around this trough will result in very dry air in the mid levels of the atmosphere which should keep the Inland NW dry. Valley high temperatures however will be falling mainly into the upper 70s and 80s as a cooler air mass gradually moves in. JW Wed Nt through Tue: We'll have to deal with two high-amp progressive upper troughs, the first Wed nt through Thurs, and the second Sat Nt through Tues. The second trough (Sat Nt through Tues) is similar to the Thurs trough passage with the exception that the ECMWF is now only slightly more progressive in pushing this mid-level wave through.
THE UPPER RIDGING OVER THE STATE WILL MAINTAIN A PRIMARILY DRY AND NON-EVENTFUL DAY. INCREASES THE CHANCE FOR ISOLATED LATE MORNING SHOWERS TRANSITIONING INTO AFTERNOON STORMS ONCE SURFACE TEMPERATURES ACHIEVE THE LOWER 90S. /ISSUED 331 AM CDT TUE JUL 21 2015/ WITH LITTLE CHANGE IN JULY'S PERSISTENT MID/UPPER LEVEL RIDGE.
1253 PM EDT TUE JUL 21 2015 A COLD FRONT WILL MOVE SOUTH ACROSS THE AREA THIS MORNING. A LARGE AREA OF HIGH PRESSURE WILL BUILD OVERHEAD ON WEDNESDAY BRINGING A STRETCH OF DRY WEATHER FOR THE SECOND HALF OF THE WEEK.
A DRY COLD FRONT WILL CROSS THE AREA EARLY TONIGHT.
EXPECT A GRADUAL LOWERING OF CIGS TO BORDERLINE MVFR AROUND 3KFT LATER THIS AFTERNOON AS AREAS OF -RA/RA SPREAD EAST ACROSS THE AREA TERMINALS AS AN UPPER TROF ADVANCES THROUGH THE REGION. CLOUDS AND RAIN WILL DIMINISH FROM WEST TO EAST LATER THIS EVENING THROUGH THE OVERNIGHT HOURS AS THE TROF SHIFTS EWD AND DRIER AIR WORKS IN BEHIND IT. /ISSUED 1152 AM CST SAT JAN 16 2016/ COLD AIR ADVECTION BEHIND WEAK COLD FRONT IS TRANSITIONING TO NUTREAL.
12Z SOUNDINGS AT KLZK AND KSHV SHOW SIGNIFICANT DRY AIR AT THE LOWEST LEVELS ALLOWING TEMPERATURES TO WET BULB DOWN AND SUPPORT SNOW.
BUT WITH THE FAST MOVEMENT OF THE LOW PRESSURE SYSTEM.
COLD FRONT HAS BACKED AS FAR WEST AS REED POINT BUT IS NOT QUITE TO BIG TIMBER. FOR THE UPDATE HAVE LOWERED HIGHS FOR TODAY AND ADJUSTED WINDS PER CURRENT LOCATION OF COLD FRONT. MODELS ARE LOOKING A BIT COOLER FOR TODAY. DRIVING TEMPS BACK TO AROUND FREEZING IN OUR WESTERN FOOTHILLS. GENERALLY WESTERLY FLOW ACROSS THE AREA BUT SUBTLE MEAN RIDGING OVER WESTERN MONTANA WILL HAVE A DISSIPATING INFLUENCE ON ANY WAVES HEADING THROUGH THE AREA.
HIGH PRESSURE OVER THE WESTERN STATES WILL FLUCTUATE IN STRENGTH BUT OVERALL WILL KEEP THE BRUNT OF WEATHER SYSTEMS TO THE NORTH OF ARIZONA.
A LITTLE COOLER IN EAST TEXAS. N WINDS OF 10-15G25KTS WILL DEVELOP BEHIND THE LOW TONIGHT AND CONTINUE THROUGH THE FORECAST PERIOD. /ISSUED 542 AM CST SAT JAN 16 2016/ A BIT COOLER THIS MORNING AS THE FRONT MOVED THROUGH LATE LAST NIGHT. HIGH PRESSURE FROM THE NORTHERN PLAINS STATES WILL CONTINUE TO BUILD SOUTH AND INTO THE SOUTHERN STATES TODAY AS A LOW WILL MOVE OFF THE COAST AROUND BROWNSVILLE THIS MORNING. THE LOW IS EXPECTED TO DEEPEN AND MOVE TO THE NORTHEAST AND INTO THE LOUISIANA COASTAL WATERS LATE THIS AFTERNOON. WITH THE INCREASING CLOUDS AND COOLER AIR MOVING IN. THIS WILL BE A FAST DEVELOPING AND MOVING SYSTEM WITH THE LOW EXPECTED TO OFF THE NE FLORIDA COAST THIS TIME TOMORROW. HIGH PRESSURE ON SUNDAY.
THIS MORNING STARTED OUT A LITTLE BIT COOLER THAN YESTERDAY WITH TEMPS RANGING IN THE LOW TO UPPER 30S. CLOUD COVER WILL PLAY A ROLE ON TEMPS TODAY EVEN WITH THE CAA IN PLACE BEHIND THE COLD FRONT THAT MOVED THROUGH OVERNIGHT.
COLD FRONT HAS PUSHED THROUGH THE FORECAST AREA LEAVING VERY STRONG WINDS IN ITS WAKE. RIDGING QUICKLY BUILDS OVER THE REGION ALLOWING WINDS TO BECOME LIGHT AND AT TIMES VARIABLE TONIGHT AND TOMORROW. BY SUNDAY NIGHT HIGH PRESSURE IS SHIFTING OFF TO THE SOUTH/EAST AHEAD OF NEXT APPROACHING SYSTEM. IMPROVED CONDITIONS ARE FORECAST ON SUNDAY WITH HIGH PRESSURE BUILDING.
1142 AM CST SAT JAN 16 2016 FOR 18Z TAFS /ISSUED 1035 AM CST SAT JAN 16 2016/ THIS MORNING STARTED OUT A LITTLE BIT COOLER THAN YESTERDAY WITH TEMPS RANGING IN THE LOW TO UPPER 30S. CLOUD COVER WILL PLAY A ROLE ON TEMPS TODAY EVEN WITH THE CAA IN PLACE BEHIND THE COLD FRONT THAT MOVED THROUGH OVERNIGHT.
417 PM EST SAT JAN 16 2016 LOW PRESSURE SOUTH OF NOVA SCOTIA WILL TRACK EAST TONIGHT INTO SUNDAY AS WEAK HIGH PRESSURE BUILDS IN FROM THE WEST.
ANOTHER COLD FRONT MOVING INTO THE REGION TOMORROW AS WELL WILL KEEP TEMPERATURES FROM REBOUNDING VERY MUCH.
ARCTIC HIGH PRESSURE BUILDING INTO THE REGION IN THE WAKE OF THIS SNOW BAND WILL YIELD SUB-ZERO TEMPERATURES TONIGHT ACROSS NORTHERN AND CENTRAL PORTIONS OF THE FORECAST AREA.
FLURRIES AND PATCHY FREEZING DRIZZLE THIS MORNING WILL GIVE WAY TO DRY CONDITIONS BY THIS AFTERNOON.
For the morning update, the major change from precious forecast is the removal of the chance of freezing rain in the Central Columbia Basin as the overnight temperatures were slightly warmer than forecast and that area is currently experiencing surface temps above freezing. Periods of snow will continue until 21-23z or so for MWH and EAT before the threat wanes however chances are good that the low clouds and IFR conditions will persist.
A large upper level low centered over south central Canada will rotate southeast through the Great Lakes this weekend. Energy associated with an upper level jet streak on the backside of the upper low plus channeled vorticity will force the arctic front southward and into northern MO by this evening.
TODAY THROUGH SUNDAY NIGHT A DEEP UPPER LOW AND ASSOCIATED COLD POOL CURRENTLY CENTERED OVER DROPPING INTO THE LAKE SUPERIOR REGION ON SUNDAY.
1232 PM CST SAT JAN 16 2016 COLD FRONT APPEARS TO HAVE FINALLY CLEARED MIDDLE TENNESSEE, WITH DRIER, COOLER AIR FILTERING INTO THE MID STATE AS HIGH PRESSURE BUILDS IN FROM THE NW. LOOK FOR LOW CLOUDS TO REMAIN LOCKED IN THROUGHOUT THE DAY, WITH A LOW PRESSURE SYSTEM RACING ALONG THE GULF COAST OVERNIGHT THAT MAY PRODUCE LIGHT SNOW ALONG THE CUMBERLAND PLATEAU LATE SATURDAY NIGHT.
249 PM CST SAT JAN 16 2016 FIRST LEAD IMPULSE AND ASSOCIATED COLD FRONT IS MOVING THROUGH THE FORECAST AREA BRINGING A QUICK SHOT OF SNOW TO THE REGION THIS AFTERNOON. HIGH PRESSURE CONTINUES TO BUILD ACROSS REGION SUNDAY NIGHT.
329 PM EST SAT JAN 16 2016 LOW PRESSURE WILL MOVE TOWARDS THE CANADIAN MARITIMES THIS EVENING. HIGH PRESSURE BUILDS IN ON SUNDAY.
HAVE UPDATED FORECAST TO CHANGE MORNING WEATHER OVER THE PLAINS TO FLURRIES AND AREAS OF FREEZING FOG WHICH IS MORE APPROPRIATE FOR THE CURRENT SITUATION. HAVE ALSO ADDED MENTION OF AREAS/PATCHY FREEZING FOG THROUGH TOMORROW MORNING. CENTRAL AND SOUTHWEST MONTANA IS UNDERNEATH THE INFLUENCE OF UNSETTLED NORTHWEST FLOW ALOFT AND A COLD FRONT PUSHING INTO THE REGION FROM THE NORTHEAST.
THE LOWER CLOUDS WILL INCH THEIR WAY SOUTHWARD TOWARD I-20.
with highs ranging from the lower 20s northwest of the Illinois River to the middle 30s south of I-70. Arctic high pressure will begin to nudge into the area today, but forecast soundings suggest a strengthening subsidence inversion just below 850 MB. So, we'll have to advect the low clouds out, as they will be unlikely to mix out.
THE GRADIENT BEGINS TO WEAKEN WITH HIGH PRESSURE CENTERED OVER S CENTRAL TEXAS. DRY COOLER AIR MASS WITH CLEAR SKIES WILL REMAIN IN PLACE WITH LIGHT WINDS. TEMPERATURES AS A RESULT WILL COOL DOWN INTO THE LOW TO MID 40S ACROSS MUCH OF THE CWA AND NEAR THE UPPER 30S IN THE NORTHERN RANCH. AS THE HIGH CONTINUES TO TRAVEL EAST A LIGHT NORTHERLY WIND PREVAILS WITH LOW HUMIDITY VALUES ACROSS THE AREA. HIGH PRESSURE WILL PROGRESS EAST INTO THE GULF WATERS WITH SE WINDS RETURNING DURING THE OVERNIGHT.
337 PM EST SAT JAN 16 2016 AN ARCTIC COLD FRONT WILL CROSS THE STATE LATE SUNDAY AND MUCH COLDER AIR WILL MOVE IN. A LARGE UPPER LEVEL LOW PRESSURE AREA WILL SETTLE OVER THE GREAT LAKES FOR A FEW DAYS. WIND SHOULD BE UNDER 8KTS FOR MOST OF THE NIGHT AS HIGH PRESSURE NOSES IN FROM THE W. BEHIND THE TRAILING COLD FRONT IS A DRASTIC CHANGE IN AIRMASS.
417 PM EST SAT JAN 16 2016 COLDER AIR WILL FILTER IN TONIGHT ON A NORTHWEST FLOW BEHIND A COLD FRONT. ANOTHER COLD FRONT WILL BRING A CHANCE OF SNOW SHOWERS ON SUNDAY ALONG WITH EVEN COLDER TEMPERATURES FOR THE START OF THE UPCOMING WEEK.
HIGHS TODAY WILL AGAIN CLIMB INTO THE LOW TO MID 60S.
WATER VAPOR LOOP INDICATED AN UPPER LOW NEAR THE MAN/ONTARIO BORDER. UPPER LOW FORECAST TO MOVE OVER LS BY SUN MORNING. UPPER LEVEL RIDGE OVER THE WEST COAST WILL GET KNOCKED DOWN WITH SHORT WAVES MOVING INTO THE WEST COAST. UPPER LEVEL RIDGE EXPECTED TO MOVE INTO THE FORECAST AREA BY THE END OF THE PERIOD WITH A SHORT WAVE UPSTREAM. A POTENTIAL PROBLEM OS WITH WATER VAPOR LOOP/FOG LOOP INDICATING AN EASTERN FLOW OVER CENTRAL CANADA OR NORTH OF MAN/ONTARIO UPPER LOW. EXPECT A MODERATING TREND WITH MUCH WARMER AIR THAN WE HAVE SEEN IN RECENT DAYS. MODELS ARE IN GOOD AGREEMENT WITH THE COLDEST AIR MOVING WELL EAST OF THE AREA AND RIDGING BUILDING TO OUR WEST LATE IN THE PERIOD.
HAVE UPDATED FORECAST TO CHANGE MORNING WEATHER OVER THE PLAINS TO FLURRIES AND AREAS OF FREEZING FOG WHICH IS MORE APPROPRIATE FOR THE CURRENT SITUATION. HAVE ALSO ADDED MENTION OF AREAS/PATCHY FREEZING FOG THROUGH TOMORROW MORNING.
A COLD FRONT WILL BRING INCREASING NORTH WINDS AND IFR/MVFR CEILINGS. BUT WE WILL NOT BE TOO SURPRISED IF THERE IS A SMALL AREA WHERE PRECIPITATION INTENSITY COMBINES WITH EDGE OF COOLER WETBULBS AND MENTIONED LATENT EFFECTS TO PRODUCT HIGHER SNOW TOTALS BEFORE MELTING COMMENCES THIS AFTERNOON.
115 PM MST SAT JAN 16 2016 HIGH PRESSURE OVER THE WESTERN STATES WILL FLUCTUATE IN STRENGTH BUT OVERALL KEEP ANY WEATHER SYSTEMS TO THE NORTH OF ARIZONA.
THE DEEP AND COLD ARCTIC HIGH PRESSURE SYSTEM WILL CONTINUE MOVING SOUTH TONIGHT.
Surface temperatures remain above freezing beneath the band. especially in the higher terrain. The ridge tops indeed stand the best chance of seeing any accumulation. Will maintain less than 1 inch amounts mainly in the higher terrain of SE OK. Would also expect snow to be dominant precip type much of the day in the higher elevations of southeast OK.
AND A STRONG UPPER LOW TO THE NORTH OF WINNIPEG WITH BROAD TROUGH INTO THE SOUTHERN PLAINS. IN BETWEEN A STRONG RIDGE OVER THE WESTERN CONUS INTO WESTERN CANADA. BROAD TROUGH THROUGH THE NORTHERN INTO THE CENTRAL PLAINS CENTERED TO THE NORTH OF WINNIPEG. A LARGE AND COLD /H5 TEMP -44C/ UPPER LEVEL LOW PRESSURE CENTER WILL DROP SOUTH FROM CANADA INTO THE GREAT LAKES REGION SUNDAY. AN ARCTIC COLD FRONT WILL REACH SOUTHERN KS TO EASTERN COLORADO BY SUNDAY AFTERNOON.
345 PM CST SAT JAN 16 2016 PATCHING FREEZING FOG MAY POSSIBLY DEVELOP LATE TONIGHT INTO SUNDAY MORNING MAINLY ACROSS THE EASTERN PANHANDLES AND PORTIONS OF THE CENTRAL PANHANDLES. A COLD FRONT WILL MOVE THROUGH THE FORECAST AREA SUNDAY BRINGING SHARPLY COLDER CONDITIONS SUNDAY INTO SUNDAY NIGHT.
/ISSUED 521 AM CST SAT JAN 16 2016/ -RA INTERMITTENTLY OCCURRING AT KCDS EARLY THIS MORNING AND COULD CHANGE OVER TO -SN OR -RASN IF TEMPERATURES FALL TO/SLIGHTLY BELOW FREEZING LATER THIS MORNING. FURTHER DEVELOPMENT IS POSSIBLE SO HAVE INSERTED A -RASN THERE GIVEN TEMPERATURES ARE ONLY 1 DEGREE AWAY FROM FREEZING. WITH TEMPS ABOVE FREEZING THUS FAR. HOWEVER MOTORISTS ARE STILL URGED TO USE CAUTION AS BRIDGES AND OVERPASS COULD BECOME SLICK DURING THE MORNING HOURS. THE PRECIP WILL BE TRANSITIONING BACK TO LIQUID AS TEMPS RETURN TO ABOVE FREEZING. TEMPS WILL BE COOLER TODAY /40S/ THANKS TO THE CLOUD COVER AND COLD FRONT USHERING IN A COOLER AIRMASS. WEAK SFC LEE TROUGHING WILL RETURN SFC WINDS TO A SRLY FLOW. THE NEXT TWO SHORT WAVE TROUGHS LOOK EVEN MORE BENIGN THAN BEFORE WITH ONLY WEAK FRONTAL PASSAGES TO ACCOMPANY THEM.
AS THIS TROUGH SWINGS INTO AND THROUGH THE REGION THIS EVENING AND OVERNIGHT.
252 PM CST SAT JAN 16 2016 FREEZING FOG POTENTIAL TONIGHT INTO SUNDAY IS THE MAIN CONCERN. LATEST OBSERVATIONS DEPICTED A PRONOUNCED SURFACE DEWPOINT GRADIENT WITH THE HIGHEST DEWPOINTS IN THE 30S SOUTHWEST OF A WOODWARD TO LAWTON TO ATOKA LINE AS OF 230 PM. THINK FREEZING FOG MAY BE A CONCERN. ADDED PATCHY FREEZING FOG MENTION FOR MOST LOCATIONS EXCEPT NORTHEAST OF A ENID TO CHANDLER LINE WHERE THE AIR NEAR THE GROUND IS DRIEST. THIS FREEZING FOG MAY REDUCE VISIBILITIES LESS THAN 3 MILES AND CREATE A LIGHT GLAZE ON ROADS. BRIDGES. WILL CLOSELY MONITOR AS A FREEZING FOG ADVISORY MAY BE NECESSARY. A COLD FRONT WILL MOVE THROUGH THE AREA AND BRING COLDER AIR AND INCREASING NORTH WINDS.
WEAK MID LVL TROFG SHOULD BRING SCT FLURRIES THIS AFTN. AND IN THE RIDGES WITH TERRAIN ENHANCEMENT. FLURRIES SHOULD TAPER OFF THIS EVE AS THE MID LVL TROF EXITS. ANOTHER COLD FRONT CROSSES DURING THE DAY SUNDAY.
UPPER LEVEL SHORT WAVE TROUGH WILL CONTINUE TO SHIFT OFF TO THE SOUTHEAST OF THE PANHANDLES THIS MORNING. /ISSUED 336 AM CST SAT JAN 16 2016/ UPPER LEVEL SHORT WAVE TROUGH WAS MOVING EAST ACROSS THE PANHANDLES THIS MORNING. BUT IT HAS NOW MOISTENED UP THE LOW LEVELS. TEMPERATURES WILL REBOUND SOME INTO THE 40S FOR HIGHS TODAY AS THE AFFECTS OF THE SHORT WAVE TROUGH MOVES AWAY. AN ARCTIC COLD FRONT WILL MOVE SOUTH ACROSS THE PANHANDLES DURING THE DAY ON SUNDAY.
320 PM EST SAT JAN 16 2016 WEAK HIGH PRESSURE BUILDS INTO THE REGION TONIGHT AND SUNDAY AS ANOTHER LOW MOVES OFF THE SOUTHEAST COAST.
THIS AFTERNOON AN ARCTIC COLD FRONT IS MAKING ITS WAY INTO THE FORECAST AREA EARLY THIS AFTERNOON.
NEAR ZERO RAIN CHANCES AND MUCH COOLER WEATHER. AN AREA OF LOW PRESSURE WILL PROGRESS EASTWARD THROUGH THE NORTHERN GULF OF MEXICO THIS AFTERNOON AND TONIGHT. EVENTUALLY PULLING A COLD FRONT THROUGH THE FLORIDA KEYS SUNDAY AFTERNOON. STRONG THUNDERSTORMS AND SUSTAINED SURFACE WINDS OF 25 TO 30 KNOTS ARE EXPECTED TONIGHT AND SUNDAY MORNING AHEAD OF THIS COLD FRONT.
Areas of freezing fog forming rapidly across SW KS this morning, as sky clears immediately after snowfall ends. Updated forecast to include areas of freezing fog through 9 AM. Highs should reach into the lower 40s. Lows tomorrow will be cooler and in the teens to lower 20s. Have gone with with cooler highs for Sunday as 850-hPa temperatures decrease to -10C to -12C.
Temperatures responded this morning by falling into the low to mid 20s. Temperatures on Sunday may not warm above freezing.
259 PM EST SAT JAN 16 2016 HIGH PRESSURE WILL BUILD INTO THE MID ATLANTIC TONIGHT. LOW PRESSURE WILL TRACK ACROSS FLORIDA TONIGHT AND THEN EAST OF CAPE HATTERAS SUNDAY. A COLD FRONT WILL PUSH THROUGH THE REGION SUNDAY EVENING.
239 PM CST SAT JAN 16 2016 A weak trof passage tonight should help clear (low) clouds west to east, eventually. That'll translate to low temps at the surface in the single digits (Sun nite and Mon nite), and sub freezing highs (Mon).
DRY CONDITIONS WILL PREVAIL INTO THE MIDDLE OF THE NEW WEEK WITH WARMER DAYTIME TEMPERATURES.
UPPER RIDGE THIS AFTERNOON AND WILL DROP ACROSS CO IN NORTHWEST FLOW LATER TONIGHT. SO THERE WILL BE SOME BLOWING SNOW CONCERNS FOR THE HIGHER PEAKS. AND LOCAL 4KM WRF SHOW SOME BREEZY WEST WINDS SPREADING DOWN THE LOWER EASTERN SLOPES INTO THE I- 25 CORRIDOR TOWARDS MORNING.
1152 AM CST SAT JAN 16 2016 COLD AIR ADVECTION BEHIND WEAK COLD FRONT IS TRANSITIONING TO NUTREAL. /ISSUED 453 AM CST SAT JAN 16 2016/ WATER VAPOR IMAGERY EARLY THIS MORNING SHOWING UPPER LEVEL TROUGH AXIS MOVING INTO THE TX/OK PNHDL REGION INTO THE TX HILL COUNTRY ATTM. AS THE TROUGH NEARS OUR REGION FROM THE WEST. LIFT IN ASSOCIATION WITH THE TROUGH WILL LIKELY GENERATE SOME PRECIPITATION LATER TODAY INTO THIS EVENING. CANNOT RULE OUT BRIEF MVFR CEILINGS AS THE TROUGH MOVES OVHD. EXPECT CLOUD COVER TO RAPIDLY SCOUR OUT IN THE WAKE OF THE TROUGH OVERNIGHT BUT THE CLOUD COVER MAY BE MORE STUBBORN AT THE LFK TERMINAL TO CLEAR OUT BEFORE 17/12Z. GRADUALLY BECOMING NW WITH THE ARRIVAL OF THE TROUGH LATER THIS MORNING/AFTERNOON.
AREA OF LOW PRESSURE MOVING INTO THE CENTRAL GULF OF MEXICO TONIGHT, WILL PUSH A WARM FRONT NEAR SW FL AROUND MIDNIGHT.
MOSTLY MOUNTAINOUS TERRAIN WILL SEE THE INCLEMENT WX LEAVING MUCH OF EASTERN UTAH AND SOME OF WESTERN COLORADO UNDER PARTLY SUNNY SKIES AND SLIGHTLY WARMER TEMPERATURES. A SHORT WAVE RIDGE BUILDS OVER THE AREA AHEAD OF A TROUGH OFF THE WEST COAST ENDING SNOWFALL OVER THE NORTHERN COLORADO MOUNTAINS.
AM EXPECTING A RATHER STEADY DECREASE IN CLOUDINESS THROUGH EARLY AFTERNOON BEFORE SOME MID AND HIGH CLOUDS MOVE TOWARD THE CO/KS BORDER FROM THE WEST AHEAD OF UPPER RIDGE AXIS. FOR SUNDAY NIGHT UPPER RIDGE APPROACHES THE CONTINENTAL DIVIDE WHICH IN TURN PUSHES THE ARCTIC AIRMASS SLOWLY EAST AND NEARLY OUT OF THE AREA. ELSEWHERE WARMER SOUTHWEST WINDS AND WARMING TEMPS ALOFT WILL ALLOW MINS TO REACH THE MID/UPPER TEENS.
HIGH PRESSURE OVER THE WESTERN STATES WILL FLUCTUATE IN STRENGTH BUT OVERALL KEEP ANY WEATHER SYSTEMS TO THE NORTH OF ARIZONA.
LOW PRESSURE IS SITUATED OVER SW TX WITH THE POLAR AIR STARTING TO PUSH INTO ND. BY THE END OF THE WEEK THERE IS STRONG INDICATIONS THAT RIDGING WILL BUILD OVER THE ROCKIES INTO THE HIGH PLAINS WHICH WILL ALLOW FOR ABOVE NORMAL TEMPS. MAIN CONCERN IS STRONG COLD FRONT WHICH SHOULD TRAVERSE AREA TONIGHT.
/issued 512 AM CST SAT JAN 16 2016/ /12Z TAFS/ A cold front will move south across West Central Texas. /issued 333 AM CST SAT JAN 16 2016/ (Today and Tonight) An upper level short wave trough extended from the Texas Panhandle into the Big Bend Region. At the surface, a cold front will quickly dive south across the area this morning and early this afternoon.
BUT WE WILL NOT BE TOO SURPRISED IF THERE IS A SMALL AREA WHERE PRECIPITATION INTENSITY COMBINES WITH EDGE OF COOLER WETBULBS AND MENTIONED LATENT EFFECTS TO PRODUCT HIGHER SNOW TOTALS BEFORE MELTING COMMENCES THIS AFTERNOON.
135 PM PST SAT JAN 16 2016 VARIABLE CLOUDINESS AND SLIGHTLY WARMER INTO SUNDAY.
929 AM PST SAT JAN 16 2016 VARIABLE CLOUDINESS AND SLIGHTLY WARMER INTO SUNDAY.
1233 PM EST SAT JAN 16 2016 NORTHWEST FLOW BEHIND A COLD FRONT WILL BRING COLDER AIR AND A CHANCE OF FLURRIES TODAY. AN ARCTIC COLD FRONT WILL BRING A CHANCE OF SNOW SHOWERS ON SUNDAY ALONG WITH EVEN COLDER TEMPERATURES FOR THE START OF THE UPCOMING WEEK. WHICH IS FORTUNATE GIVEN THE TEMPERATURES (VERY CLOSE TO FREEZING). EXPECT ONLY MINIMAL RECOVERY IN TEMPERATURES TODAY WITH HIGHS ONLY IN THE LOWER TO MID 30S. BUT STILL EXPECT CLOUDS TO LINGER AS THE LOW LEVEL MOISTURE REMAINS HIGH. EXPECT HIGHS ON SUNDAY TO RANGE FROM THE LOWER 20S NORTHWEST TO MID 30S IN THE SOUTHEAST.

650 PM CDT Sun Jun 28 2015 A surface cold front has cleared through the majority of the area early this afternoon, precluding storm chances in all but north central through central MO.
1017 PM EDT SUN JUN 28 2015 A COLD FRONT HAS MOVED INTO THE AREA AND BECOME NEARLY STATIONARY NEAR THE EASTERN MIDLANDS AND COASTAL.
WE ARE COOLING QUICKER THAN PREVIOUSLY EXPECTED WITH THE LOW LEVEL DRY AIR. ENJOY TONIGHT AS WE EXPECT WARMER CONDITIONS BEGINNING TO RETURN ON MONDAY. AS OF 2 PM THE COLD FRONT WAS JUST ABOUT CLEAR OF THE FORECAST WITH ONLY A FEW SCATTERED SHOWERS STILL IN BARBOUR COUNTY AND EXITING TO THE SOUTH AND EAST. WE COULD SEE A FEW SPOTS IN THE 50S IN THE NORTH BUT THOSE WOULD BE THE NORMALLY COOLER SPOTS.
HIGH PRESSURE (1019 MILLIBARS) WAS CENTERED OVER THE SOUTHEAST GULF OF MEXICO. DEEP-LAYERED TROUGHING COVERS THE EASTERN THIRD OF THE U.
1039 PM EDT SUN JUN 28 2015 LOW PRESSURE WILL LINGER OVER THE AREA THROUGH MONDAY MORNING BRINGING A CONTINUATION OF SCATTERED SHOWERS AND DRIZZLE.
Widely scattered convection will remain possible for a few more hours as weak isentropic upglide interacts with a surface cold front and remaining outflow boundaries. Focus for thunderstorm development will be associated with a southward moving cold front entering central Missouri this afternoon.
ONLY 5 DAYS SINCE 1875 HAVE BEEN AS WARM OR WARMER IN BOISE. ISOLATED SHOWERS AND THUNDERSTORMS IN SE OREGON AND THE HIGHER TERRAIN OF SW IDAHO.
/ISSUED 306 PM CDT SUN JUN 28 2015/ THE COLD FRONT THAT WAS TRYING TO MOVE INTO OUR REGION IS LIKELY STALLED OUT NOW.
A WARMING TREND IS EXPECTED OVER THE NEXT FEW DAYS AS A RIDGE OF HIGH PRESSURE SLIDES WEST. THE CURRENT SATELLITE WATER VAPOR IMAGE IS SHOWING A HIGH AMPLITUDE RIDGE OF HIGH PRESSURE OVER THE WESTERN STATES. A TROUGH OF LOW PRESSURE CONTINUES TO SLIDE UP THE COAST OF OREGON TOWARDS WASHINGTON STATE. BOTH MODELS SLIDE THE CENTER OF THE RIDGE OF HIGH PRESSURE SLIGHTLY WEST TOMORROW AS THE PREVIOUSLY MENTIONED TROUGH OF LOW PRESSURE PUSHES INTO CANADA.
722 PM EDT SUN JUN 28 2015 A COLD FRONT HAS MOVED INTO THE AREA AND BECOME NEARLY STATIONARY NEAR THE EASTERN MIDLANDS AND COASTAL.
