649 PM CDT TUE JUN 23 2015 2PM SURFACE MAP INDICATES THE COLD FRONT THE PRODUCED THE SEVERE WEATHER TO OUR NORTH AND WEST LAST EVENING HAS FINALLY SETTLED SOUTH OF OUR FORECAST AREA. WEAK HIGH PRESSURE WILL DRIFT ACROSS THE AREA TONIGHT KEEPING THINGS QUIET BEFORE THE RETURN FLOW SETS UP OVER FAR WEST CENTRAL ILLINOIS WEDNESDAY MORNING. WE SHOULD SEE A GRADUAL INCREASE IN RAIN CHANCES ACROSS THE WEST AFTER MIDNIGHT AS THE FRONTAL BOUNDARY THAT JUST PUSHED SOUTH OF OUR AREA THIS AFTERNOON STARTS TO MAKE THE TRIP BACK NORTH AS A WARM FRONT. THE WARM FRONT WILL SLOWLY LIFT NORTHWARD TOMORROW.
ESPECIALLY OVER THE HIGHER TERRAIN OF NORTHERN ARIZONA. AN INVERTED TROUGH AND ASSOCIATED TROPICAL MOISTURE CURRENTLY OVER NORTH CENTRAL MEXICO WILL CONTINUE TO RETROGRADE WESTWARD UNDER A FLAT RIDGE CENTERED OVER THE SOUTHERN PLAINS.
12Z UA ANALYSIS HAS AN 850MB COLD FRONT FROM NEAR KDET INTO NORTHERN KANSAS AND AN 850MB HIGH OVER SOUTH DAKOTA. 18Z SFC DATA PLACES THE COLD FRONT FROM NEAR KCLE INTO SOUTHERN KANSAS. THE NOCTURNAL CONVECTIVE COMPLEX SHOULD SLOWLY OVERSPREAD ALL BUT THE HIGHWAY 20 CORRIDOR BY MID DAY WEDNESDAY.
1229 AM EDT WED JUN 24 2015 A COOLER AND LESS HUMID AIRMASS WILL BE USHERED IN FOR OVERNIGHT INTO WEDNESDAY.
612 PM CDT TUE JUN 23 2015 A BROAD AREA OF HIGH PRESSURE WILL REMAIN OVER OUR AREA TONIGHT. WITH A WARM FRONT STRETCHING EASTWARD THROUGH SOUTHERN IA. A WEAK COLD FRONT WILL ALSO MOVE THROUGH NORTHERN MN DURING THIS TIME. COMBINED WITH THE FAVORABLE BULK SHEAR IN THIS AREA AS WELL AS INCREASING SURFACE MOISTURE (DEWPOINTS INCREASING INTO THE LOWER 60S). AS ZONAL FLOW BECOMES HIGHLY AMPLIFIED AS SIGNIFICANT RIDGING DEVELOPS OVER THE WESTERN PART OF THE CONTINENT AND DOWNSTREAM TROUGH TAKES PLACE OVER THE EAST.
754 PM EDT TUE JUN 23 2015 A COLD FRONT ALONG WITH THE ASSOCIATED CHANCE FOR SHOWERS/STORMS WILL CLEAR THE AREA BY EARLY THIS EVENING. HIGH PRESSURE AND A DRIER NORTHWEST FLOW WILL MOVE IN FOR TONIGHT AND WEDNESDAY.
A HIGH PRESSURE SYSTEM OVER THE WESTERN NORTH ATLANTIC WILL MAINTAIN MODERATE TO FRESH EAST TO SOUTHEAST BREEZES ACROSS FLORIDA KEYS COASTAL WATERS OVERNIGHT.
945 PM EDT TUE JUN 23 2015 A COLD FRONT WILL SHIFT EASTWARD ACROSS THE NORTH COUNTRY DURING THE FIRST HALF OF TONIGHT WITH BREEZY CONDITIONS AND ISOLATED THUNDERSTORMS EXITING TO THE EAST BY EARLY EVENING. THE COLD FRONT WILL USHER IN A DRIER AND MORE SEASONABLE AIR MASS FOR THE REMAINDER OF THE WORK WEEK. ONLY OTHER CHANGE (ACTUALLY FOR TOMORROWS FORECAST) WAS TO ADD SLIGHT CHANCE OF THUNDER FOR WEDNESDAY AFTERNOON/EARLY EVENING BASED OFF UPSTREAM OBSERVATIONS ACROSS THE UPPER MIDWEST/NRN GREAT LAKES AND EVIDENCE OF AT LEAST SOME SLIGHTLY STEEPER MID LEVEL LAPSE RATES ALONG WEAK NRN STREAM TROUGH AXIS.
GENERALLY FAVORABLE BOATING CONDITIONS WITH ATLC RIDGE AXIS MEANDERS BTWN THE CENTRAL AND SRN FL PENINSULA WHILE A SERIES OF LOW PRESSURE SYSTEMS WORK THEIR WAY ACRS THE ERN CONUS.

729 PM EDT TUE JUN 23 2015 COLD FRONT DROPS SOUTH TONIGHT. TEMPERATURES SHOULD BE COOLER FOR THE WEEKEND.
624 PM CDT Tue Jun 23 2015 For the rest of the afternoon, a line of storms is expected to continue riding along the thermal ridge/edge of the capping inversion, basically along a line from Atchison county KS to Sedalia. By tomorrow morning, ridging will be fully entrenched across the CWA and the boundary will have lifted well north of the MO/IA border, keeping the area mainly dry except potentially in very far northeast portions of the CWA where the boundary and upper-level flow begin to arc slightly northwest- to southeast-ward. Have issued a special weather statement for the KC metro area mentioning heat issues, and may need to issue a small heat advisory if temperatures look similar or a degree or two warmer with the next model runs.
1042 PM EDT TUE JUN 23 2015 ABOVE NORMAL TEMPERATURES WILL CONTINUE ACROSS THE REGION THIS WEEK AS THE SUBTROPICAL RIDGE HOLDS ACROSS THE SOUTHERN STATES. SOMEWHAT COOLER TEMPERATURES AND AN INCREASED CHANCE FOR AFTERNOON AND EVENING THUNDERSTORMS ARE IN STORE FOR THE WEEKEND AS AN UPPER LEVEL TROUGH BUILDS ACROSS THE EASTERN CONUS. UPPER RIDGE CENTERED JUST TO THE WEST OF THE AREA WILL CONTINUE THROUGH THE SHORT TERM. WEAK UPPER LEVEL IMPULSES MOVING AROUND THE PERIPHERY OF THE UPPER RIDGE AND STRONG DAYTIME HEATING WILL PROVIDE THE ENERGY FOR SCATTERED MAINLY AFTERNOON AND EVENING THUNDERSTORMS.
1218 AM EDT WED JUN 24 2015 VERY QUIET CONDITIONS FOR THE TERMINAL FORECAST PERIOD AS HIGH PRESSURE DRIFT THROUGH THE SOUTHERN LAKES REGION.
LOOKS LIKE A SIMILAR SET UP ON WEDNESDAY WITH ANOTHER WEAK DISTURBANCE MOVING AROUND THE RIDGE TO PROVIDE LATE IN THE AFTERNOON SCATTERED SHOWERS AND STORMS. NOTED THAT K-INDICES ARE EXPECTED TO CLIMB ABOVE THE 40 MARK WITH AMPLE DEEP MOISTURE BROUGHT IN FROM THE EAST THANKS TO A MID LEVEL RIDGE OVER THE SOUTHEASTERN STATES AND AN UPPER LEVEL LOW OVER THE SOUTHWESTERN GULF.
MUCH OF THE AREA WAS STILL IN THE LOWER TO MID 80S WITH DEWPOINTS IN THE MID 70S.
732 PM EDT TUE JUN 23 2015 A COLD FRONT WILL SHIFT EASTWARD ACROSS THE NORTH COUNTRY DURING THE FIRST HALF OF TONIGHT WITH BREEZY CONDITIONS AND ISOLATED THUNDERSTORMS EXITING TO THE EAST BY EARLY EVENING. THE COLD FRONT WILL USHER IN A DRIER AND MORE SEASONABLE AIR MASS FOR THE REMAINDER OF THE WORK WEEK.
/ISSUED 230 PM CDT TUE JUN 23 2015/ ELONGATED RIDGE AXIS JUST TO OUR NORTH WILL RELOCATE TO THE EAST AS A WEAK WESTWARD MOVING UPPER TROUGH CROSSES THE BIG BEND AND NORTHERN MEXICO LATE TONIGHT AND TOMORROW.

SOMEWHAT COOLER TEMPERATURES AND AN INCREASED CHANCE FOR AFTERNOON AND EVENING THUNDERSTORMS ARE IN STORE FOR THE WEEKEND AS AN UPPER LEVEL TROUGH BUILDS ACROSS THE EASTERN CONUS. UPPER RIDGE CENTERED JUST TO THE WEST OF THE AREA WILL CONTINUE THROUGH THE SHORT TERM. WEAK UPPER LEVEL IMPULSES MOVING AROUND THE PERIPHERY OF THE UPPER RIDGE AND STRONG DAYTIME HEATING WILL PROVIDE THE ENERGY FOR SCATTERED MAINLY AFTERNOON AND EVENING THUNDERSTORMS.
WELL INTO INTO THE MID 50S FOR SOME SITES ALONG THE LOWER COLORADO RIVER VALLEY. WEDNESDAY AFTERNOON/EVENING STILL LOOKS TO BE ON TRACK TO INTRODUCE THUNDERSTORMS OVER THE HIGHER TERRAIN EAST/SOUTH OF PHOENIX. WITH THE POTENTIAL FOR THESE STORMS TO PUT OUT A WELL- ORGANIZED OUTFLOW BOUNDARY AND STRONG GUSTY WINDS ACROSS THE LOWER DESERTS IN MARICOPA AND PINAL COUNTY. AS A DEEP INVERTED TROUGH APPROACHES FROM THE EAST AND BOOSTS DEWPOINTS AND LL TO ML MIXING RATIOS AS EARLY AS MIDDAY. THE UL RIDGE TRANSITIONS THROUGH THE FOUR CORNERS HEADING INTO THE GREAT BASIN.
00Z NAM MORE VIGOROUS AND FARTHER NORTH WITH SHORT WAVE TROF AND SFC FRONT LOCATION MOVING ACRS AREA WED NGT. HIGH PRESSURE AND NW FLOW ALOFT WILL KEEP THINGS QUIET THIS EVENING AND INTO WEDNESDAY MORNING. A LOW PRESSURE SYSTEM OVER THE GREAT PLAINS WILL BEGIN TO APPROACH SOUTHERN WISCONSIN ON WEDNESDAY AFTERNOON.

AN UNSETTLED AND POTENTIALLY WET PATTERN WILL PERSIST FROM LATE WEEK INTO THE WEEKEND WITH COOLER TEMPERATURES EXPECTED. COLD FRONT AND MUCH DRIER AIR JUST MOVING INTO STATE COLLEGE NOW. FCST MINS WILL RANGE FROM AROUND 50F IN THE NW TO THE LOW 60S IN THE SE. AS WESTERN RIDGE BUILDS.
BROAD UPPER RIDGE OVER THE SOUTHERN ROCKIES AND INTO THE SOUTHERN PLAINS WILL KEEP WESTERLY FLOW ALOFT OVER THE STATE THROUGH WEDNESDAY. HIGH PRESSURE OVER THE GREAT PLAINS AND LOW PRESSURE OVER SOUTHEASTERN COLORADO IS BRINGING SOUTHEASTERLY WINDS ACROSS THE FORECAST AREA. EXPECT THE INVERSION OVER THE PLAINS TO BE ERODED BY WEDNESDAY FOR SLIGHTLY WARMER TEMPERATURES OVER THE EASTERN PLAINS. THIS WILL LIKELY COOL HIGH TEMPERATURES OVER THE HIGH COUNTRY BY A COUPLE DEGREES OVER TODAY.
1002 PM EDT TUE JUN 23 2015 HIGH PRESSURE WILL BUILD INTO THE AREA TONIGHT.
1041 PM EDT TUE JUN 23 2015 HIGH PRESSURE WILL BUILD INTO THE GREAT LAKES REGION THROUGH WEDNESDAY BRINGING FAIR BUT COOLER WEATHER.

754 PM EDT TUE JUN 23 2015 A COLD FRONT WILL SAG SOUTH OF THE AREA THIS EVENING BRINGING DRIER AIR AND CLEARING SKIES. GUSTY NORTHWESTERLY WINDS BEHIND THE FRONT WILL DIMINISH THIS EVENING AS HIGH PRESSURE BUILDS INTO THE GREAT LAKES.
635 PM CDT TUE JUN 23 2015 FOR 00Z TAFS /ISSUED 345 PM CDT TUE JUN 23 2015/ LOW PRESSURE SYSTEM MOVING OUT OF THE GREAT LAKES REGION AND INTO THE NE US HAS A WEAK COLD FRONT EXTENDING SW THROUGH THE OH VALLEY AND INTO THE CENTRAL PLAINS STATES.
840 PM EDT TUE JUN 23 2015 A COLD FRONT ALONG WITH THE ASSOCIATED CHANCE FOR SHOWERS/STORMS WILL CLEAR THE AREA BY EARLY THIS EVENING. HIGH PRESSURE AND A DRIER NORTHWEST FLOW WILL MOVE IN FOR TONIGHT AND WEDNESDAY.
726 PM EDT TUE JUN 23 2015 MOSTLY CLEAR SKIES CAN BE EXPECTED THIS EVENING AND OVERNIGHT AS HIGH PRESSURE DRIFTS OVERHEAD. HIGH PRESSURE WILL SLIDE ACROSS THE REGION PROVIDING CLEAR SKIES AND LIGHT WINDS TONIGHT.
HIGH PRESSURE WILL SLOWLY STRENGTHEN ACROSS THE REGION OVER THE NEXT FEW DAYS RESULTING IN A GRADUAL WARMING TREND. WATER VAPOR LOOP SHOWS A LARGE CLOSED LOW OVER THE GULF OF ALASKA WITH A WAVE EJECTING EAST OVER MONTANA. MEANWHILE THE RIDGE HAS SLID SOUTHEAST FROM THE FOUR CORNERS INTO THE PLAINS. HAVE A MENTION FOR DRY THUNDERSTORMS EAST OF A KANAB TO DUCHESNE LINE BASED ON MOISTURE PROFILES AND WEAK WAVES ROTATING AROUND THE RIDGE TO THE SOUTHEAST OF THE AREA. HIGH PRESSURE REMAINS OVER THE FORECAST AREA THIS AFTERNOON. AND SOME CUMULUS CLOUDS ARE VISIBLE OVER THE HIGHER TERRAIN OF SOUTHERN UTAH AS WELL AS THE UINTAS. AND BECAUSE OF THIS THE THREAT OF ISOLATED THUNDERSTORMS SPREADS INTO THE HIGHER TERRAIN OF NORTHERN UTAH.
747 PM EDT TUE JUN 23 2015 A COLD FRONT WILL CROSS SOUTHEAST OHIO THIS AFTERNOON WITH HIGH PRESSURE BUILDING IN FROM THE NORTH TONIGHT.
1013 PM EDT TUE JUN 23 2015 A COLD FRONT WILL PASS THROUGH THE REGION TONIGHT. HIGH PRESSURE WILL BRIEFLY BUILD OVERHEAD WEDNESDAY.
1157 PM CDT TUE JUN 23 2015 RELATIVELY QUIET WEATHER WILL CONTINUE THROUGH MUCH OF THE NIGHT AS A COLD FRONTAL BOUNDARY REMAINS JUST SOUTH OF ILLINOIS AND A WEAKENING MCS WEST OF IL HEADS TOWARD SOUTHERN IL. 2PM SURFACE MAP INDICATES THE COLD FRONT THE PRODUCED THE SEVERE WEATHER TO OUR NORTH AND WEST LAST EVENING HAS FINALLY SETTLED SOUTH OF OUR FORECAST AREA. WEAK HIGH PRESSURE WILL DRIFT ACROSS THE AREA TONIGHT KEEPING THINGS QUIET BEFORE THE RETURN FLOW SETS UP OVER FAR WEST CENTRAL ILLINOIS WEDNESDAY MORNING. WE SHOULD SEE A GRADUAL INCREASE IN RAIN CHANCES ACROSS THE WEST AFTER MIDNIGHT AS THE FRONTAL BOUNDARY THAT JUST PUSHED SOUTH OF OUR AREA THIS AFTERNOON STARTS TO MAKE THE TRIP BACK NORTH AS A WARM FRONT. THE WARM FRONT WILL SLOWLY LIFT NORTHWARD TOMORROW.
02 UTC surface analysis shows a cold front extending from East Tennessee down through West Central Georgia and South Central Alabama, just to the west of our region. A weak area of low pressure appeared to be forming along the front across SE Louisiana.
418 PM CST TUE JAN 26 2016 THE HIGH TODAY "60" WAS REACHED BEFORE SUNRISE WITH TEMPERATURES FALLING INTO THE MID 40S ACROSS CENTRAL LA AND UPPER 40S TO NEAR 50 OVER SOUTH CENTRAL LOUISIANA. WE ARE ABOUT DONE WITH THE RAINS BUT THE LAST BATCH OF RAIN IS DEVELOPING OVER CENTRAL TEXAS AND WILL MOVE OVER SE TX AND SRN LA THIS EVENING AS THE BASE OF THE UPPER LEVEL TROF SWINGS THROUGH WITH DRIER AIR FINALLY SPILLING IN AFTER MIDNIGHT. BY MORNING WITH LOWER DEW POINTS AND PTCLDY SKIES TEMPS WILL HEAD TOWARDS THE LOWER 40S MOST LOCATIONS AND UPPER 30S IN CNTRL LA.
AN UPPER LEVEL TROF WILL ALSO MOVE INTO THE MIDSOUTH OVERNIGHT. THE UPPER TROF WILL KEEP ABUNDANT HIGH CLOUDS OVER MUCH OF THE CWA.
The longwave trough extending from the Great Lakes region down through Texas has been progressing to the East all day. This has allowed for continued subsidence over northeastern Kansas associated with a longwave ridge building over the Northern Rockies and Northern Plains. But it seems reasonable that again with some snow cover in place generally North of I-70 that temps will be held down just a bit reaching low to mid 40s while areas generally South of I-70 see high temps in the low 50s for Wednesday. Considering the low level moisture due to associated snow and recent melt off, have inserted some areas of fog over remaining snow pack and just patchy areas outside of that generally along or north of I-70. While models show two mid-level troughs skimming across the northern U.
Above normal temperatures will be the primary focus over the next several days, as ridging builds over the High Plains and surface winds turn to the west southwest.
930 PM EST TUE JAN 26 2016 THE AVIATION SECTION HAS BEEN UPDATED BELOW HIGH PRESSURE IS EXPECTED ACROSS THE AREA THROUGH THE END OF THE WEEK. SHEARING UPPER TROUGH WILL PASS OVER THE LOCAL AREA TONIGHT. A FEW FLURRIES MAY STILL BE POSSIBLE WEDNESDAY MORNING AS TONIGHT/S UPPER TROUGH WILL BE IN THE PROCESS OF PASSING OVER THE AREA AT THAT TIME.
727 PM EST TUE JAN 26 2016 A TROUGH OF LOW PRESSURE WILL APPROACH FROM THE GREAT LAKES TONIGHT. A COLD FRONT WILL CROSS THE REGION ON WEDNESDAY. PRODUCING A FEW SNOW SHOWERS AND LIGHT ACCUMULATIONS OVER THE HIGHER TERRAIN.
COLD AIR ADVECTION WILL CONTINUE DESPITE SOME PERSISTENT SKY COVER AND TEMPERATURES WILL DROP INTO THE LOWER 30S ACROSS NORTHERN AREAS TO AROUND 40 IN THE SOUTH. BUT THEY ARE IN NO HURRY TO MOVE THIS WAY AS MID LEVEL SW FLOW CONTINUES TO STREAM MOISTURE UP AND OVER THE COOL AIR IN THE LOWER LEVELS.
1024 PM EST TUE JAN 26 2016 A COLD FRONT WILL MOVE THROUGH THE FORECAST AREA LATE TONIGHT. THE FRONT WILL STALL OFF THE COAST AND A SERIES OF LOW PRESSURE CENTERS WILL MOVE NORTHEASTWARD ALONG THE FRONT.
GUSTY NORTH WINDS PREVAIL IN WAKE OF STRONG COLD FRONT THAT PASSED THIS MORNING. POSITIVELY TILTED TROUGH AXIS REMAINS TO THE NORTHWEST OF THE REGION AND WILL GRADUALLY SWING ACROSS SOUTH TEXAS THROUGH THE PERIOD. A SECONDARY SURGE OF HIGH PRESSURE WILL TIGHTEN PRESSURE GRADIENT OVER GULF WATERS TONIGHT. BUT LOWS WILL STILL FALL INTO THE LOW TO MID 40S. WE COULD SEE SOME FREEZING TEMPERATURES BRIEFLY. BUT CURRENTLY THINK TEMPS WILL FALL TO JUST ABOVE FREEZING OVER INLAND PORTIONS OF THE REGION.
712 PM EST TUE JAN 26 2016 COLDER AIR WILL CONTINUE TO FILTER IN OVERNIGHT WITH TEMPERATURES FALLING INTO THE LOWER TO MIDLE 20S BY WEDNESDAY MORNING. MAINLY DRY CONDITIONS AND LIGHTER WINDS ARE THEN EXPECTED ON WEDNESDAY WITH HIGHS REACHING INTO THE LOWER 30S. SECONDARY VORT MAX EMBEDDED IN LARGER SCALE/POSITIVELY TILTED UPPER TROUGH WILL DROP SE THROUGH THE LOWER GREAT LAKES THIS EVENING.
532 PM CST TUE JAN 26 2016 /00Z TAFS/ Light rain along with MVFR CIGS and visibilities will affect areas south of the the I-20 corridor this evening, with most terminals rising back to VFR around midnight as the upper trough and light rain ends. The main band of snow was back to the west across the Trans Pecos and Permian Basin, where temperatures were in the lower to mid 30s. 21 (Wednesday night through next Tuesday) By Wednesday night, the upper level trough will be replaced by dry north/northwest flow aloft.
Temperatures along the I-10 corridor are in the lower to upper 30s and will fall a few more degrees through late evening. Could see a few slick spots develop on bridges and overpasses but this should be rather isolated. /issued 532 PM CST TUE JAN 26 2016/ /00Z TAFS/ Light rain along with MVFR CIGS and visibilities will affect areas south of the the I-20 corridor this evening, with most terminals rising back to VFR around midnight as the upper trough and light rain ends. The main band of snow was back to the west across the Trans Pecos and Permian Basin, where temperatures were in the lower to mid 30s. 21 (Wednesday night through next Tuesday) By Wednesday night, the upper level trough will be replaced by dry north/northwest flow aloft.
AREAS SUCH AS THE HIGH ELEVATION MORENO VALLEY NEAR KAXX WILL LIKELY SEE SOME FOG OR LOW CLOUD DEVELOPMENT OVERNIGHT.
1005 PM EST TUE JAN 26 2016 A COLD FRONT CROSSES THE TRI-STATE INTO THE EARLY MORNING HOURS.
1011 PM EST TUE JAN 26 2016 THE NEAR TERM SECTION HAS BEEN UPDATED BELOW HIGH PRESSURE IS EXPECTED ACROSS THE AREA THROUGH THE END OF THE WEEK. SOME GRADUAL CLEARING WILL TAKE PLACE OVERNIGHT WITH OVERNIGHT LOWS DIPPING INTO THE LOW TO MID 20S. SHEARING UPPER TROUGH WILL PASS OVER THE LOCAL AREA TONIGHT. A FEW FLURRIES MAY STILL BE POSSIBLE WEDNESDAY MORNING AS TONIGHT/S UPPER TROUGH WILL BE IN THE PROCESS OF PASSING OVER THE AREA AT THAT TIME.
LATE EVENING ADJUSTMENTS TO PRECIP TYPE WITH REMOVAL OF FREEZING DRIZZLE FROM THE NORTHERN RIDGES AS DRIER AIR CONTINUES TO SWEEP EAST AND SFC DEW POINT SPREADS ARE WIDENING TO OVER 8 DEGREES F. ALSO NARROWED THE WINDOW FOR A SLIGHT CHANCE OF FREEZING DRIZZLE SOUTHERN RIDGES AFTER MIDNIGHT. COLD FRONT CROSSING THE RIDGES AT 22Z WITH COLD ADVECTION TAKING TEMPERATURES BACK TOWARD THE SEASONAL AVERAGES OVERNIGHT. LOWERED POPS OVER THE RIDGES WITH SCT RAIN AND SNOW SHOWERS FIRST HALF OF TONIGHT. FORECAST SOUNDINGS SHOW A BRIEF WINDOW FOR FREEZING DRIZZLE IN THE RIDGES AFTER MIDNIGHT.
630 PM EST TUE JAN 26 2016 PATCHY FREEZING DRIZZLE AND MAYBE A SNOW SHOWER POSSIBLE IN THE MOUNTAINS TONIGHT.
405 PM MST TUE JAN 26 2016 HIGH PRESSURE CONTINUES TO AMPLIFY OVER THE WESTERN US AND WILL FILTER IN WARMER AIR ALOFT OVER THE NEXT 24 HOURS.
COLD FRONT CROSSING THE RIDGES AT 22Z WITH COLD ADVECTION TAKING TEMPERATURES BACK TOWARD THE SEASONAL AVERAGES OVERNIGHT. LOWERED POPS OVER THE RIDGES WITH SCT RAIN AND SNOW SHOWERS FIRST HALF OF TONIGHT. FORECAST SOUNDINGS SHOW A BRIEF WINDOW FOR FREEZING DRIZZLE IN THE RIDGES AFTER MIDNIGHT. THIS WILL ALLOW FOR THE BOUNDARY LAYER DEPTH TO MORE SUFFICIENTLY INTERSECT THE LOWER SECTION OF THE DENDRITIC GROWTH ZONE.
/issued 304 PM CST TUE JAN 26 2016/ Precipitation mostly in the form of snow is falling across portions of the area with the heaviest precipitation currently falling across the Lower Trans Pecos, Davis/Apache Mountains, and the southern Permian Basin. Models are showing precipitation lingering across the lower Trans Pecos and southern Permian Basin into this evening. The upper level trough that was over the area today will begin to move eastward on Wednesday.
Precip should completely come to an end by midnight however with some roadways still wet, there remains some concern for this water to freeze by early morning as temperatures drop below freezing. In addition, could see some areas of freezing fog that would add light ice accumulations. /issued 304 PM CST TUE JAN 26 2016/ Precipitation mostly in the form of snow is falling across portions of the area with the heaviest precipitation currently falling across the Lower Trans Pecos, Davis/Apache Mountains, and the southern Permian Basin.

The upper level trough that was over the area today will begin to move eastward on Wednesday.
FIRST AND FOREMOST THE COLD FRONT IS ALREADY WELL TO THE SOUTHEAST OF THE CWA WHICH IS MUCH QUICKER THAN ORIGINALLY FORECAST. TEMPS ARE STILL IN THE LOWER 40S AND WITH CLOUD COVER REMAINING. LOWS WILL ONLY DROP TO RIGHT AROUND FREEZING AND THAT WILL BE TOWARDS SUNRISE. THINKING WITH THE HIGH PRESSURE ALREADY BUILDING IN AND MUCH DRIER AIR IN PLACE.
633 PM EST TUE JAN 26 2016 MVFR TO IFR CONDITIONS ACROSS THE TERMINALS CURRENTLY AS PRECIPITATION MOVES THROUGH THE AREA ALONG A COLD FRONT.
1001 PM EST TUE JAN 26 2016 A SECONDARY COLD FRONT ACROSS THE NORTHERN LAKES WILL SWING ACROSS THE AREA LATE TONIGHT. HIGH PRESSURE WILL MOVE QUICKLY ACROSS THE UPPER OHIO VALLEY WEDNESDAY.
619 PM EST TUE JAN 26 2016 A SECONDARY COLD FRONT ACROSS THE NORTHERN LAKES WILL SWING ACROSS THE AREA LATE TONIGHT. HIGH PRESSURE WILL MOVE QUICKLY ACROSS THE UPPER OHIO VALLEY WEDNESDAY.
654 PM PST TUE JAN 26 2016 A weak weather system tracking into the area into Wednesday will bring areas of light valley rain and mountain snow, and possibly some isolated spot of freezing rain.
EXPECT MVFR CONDITIONS TO CONTINUE TO DEVELOP ACROSS THE REST OF THE CWA TONIGHT AS OVERRUNNING CONDITIONS DEVELOP WITH WARMER AND MOIST AIR ALOFT MOVING ACROSS COOLER AIR AT THE SURFACE. THE COLD FRONT HAS ESSENTIALLY CLEARED THE AREA. OVERRUNNING WILL SET UP UNTIL HIGH PRESSURE SPREADS OUT AND MODIFIES. AND THE UPSTREAM MID LEVEL TROUGH SHIFTS FAR ENOUGH EAST SO THAT THE SUPPORTING LIFT MOVES OFFSHORE.
