359 PM EDT FRI APR 17 2015 HIGH PRESSURE WILL BUILD INTO THE AREA TONIGHT AND SATURDAY BEFORE MOVING OFF TO THE EAST ON SATURDAY NIGHT.
500 PM EDT FRI APR 17 2015 CLOUDS CONTINUE TO SLOWLY BREAK UP THIS AFTERNOON AS HIGH PRESSURE BUILDS INTO THE OH VALLEY REGION. A CLOSED UPPER LOW EJECTS INTO THE CENTRAL PLAINS. CROSSING THE LOWER MS RIVER VALLEY AND NORTHEAST INTO THE OH AND TN VALLEYS.
1150 AM MDT FRI APR 17 2015 A WEAK RIDGE IS OVER THE ZONES AND THE AIRMASS WILL REMAIN WARM AND DRY TODAY. WEAK HIGH PRESSURE ALOFT WILL KEEP THE AIRMASS WARM AND DRY TODAY. AN ASSOCIATED COLD FRONT WILL CROSS THE CANADIAN BORDER AND MOVE THROUGH KCTB AROUND 09Z AND THROUGH KGTF AND KHVR 11-12Z.
353 PM EDT FRI APR 17 2015 HIGH PRESSURE WILL SETTLE OVER SOUTHEASTERN OHIO TONIGHT THEN A STRONGER AREA OF HIGH PRESSURE IS EXPECTED TO RIDGE INTO THE AREA FROM CENTRAL ONTARIO.
MOSTLY CLEAR THIS EVENING WITH SHORT WAVE UPPER RIDGE OVEHHEAD. A SHORT WAVE TROUGH WILL COME IN FROM THE NORTHWEST LATE INCREASING NORTHWEST WINDS. AND SLIGHTLY COOLER TEMPS.
ALTHOUGH SEVERE WEATHER WITH LARGE HAIL IS POSSIBLE LATER TODAY ALONG AND AHEAD OF THE DRYLINE AFTER MORNING AND EARLY AFTERNOON CONVECTION MOVES OFF TO THE EAST, THERE IS A LOT OF UNCERTAINTY AS TO WHETHER THE LOWER LEVELS CAN RECOVER ENOUGH FOR SUFFICIENT SURFACE BASED CAPE. GIVEN THE COLD UPPER LEVEL TEMPERATURES ON THE HIGHER TERRAIN OF WESTERN KANSAS, THERE WILL PROBABLY BE ENOUGH INSTABILITY FOR LARGE HAIL AT LEAST THE SIZE OF QUARTERS OR HALF DOLLARS. THE VERY SLOW MOVING UPPER LOW WILL CONTINUE TO PROVIDE CHANCES FOR PRECIPITATION UNTIL IT FINALLY CLEARS THE REGION.
330 PM CDT FRI APR 17 2015 CURRENT SCENARIO HAS MATURE UPPER LOW OVER THE CENTRAL ROCKIES WITH LEADING SHORT WAVE LIFTING NORTHEAST THROUGH NE.
315 PM CDT FRI APR 17 2015 315 PM CDT MAIN WEATHER FEATURE OF NOTE THIS AFTERNOON ON W/V IMAGERY IS PROMINENT CLOSED UPPER LOW OVER THE FOUR CORNERS REGION. RESULTING IN BROAD RIDGING OVER THE TOP OF OUR AREA. SO EXPECTING OVERNIGHT LOWS TO ONLY DROP TO THE LOWER TO MID 50S. COLD FRONT BOUNDARY TRAILING FROM WEAK LOW PRESSURE MOVING INTO QUEBEC SATURDAY MORNING WILL SERVE AS A BACKDOOR FRONT AND TURN WINDS TO A GUSTY NORTHEAST TO EAST-NORTHEAST DIRECTION ON SATURDAY NORTH OF I-80. AS WELL AS COOLER CONDITIONS FOR INLAND AREAS CLOSER TO THE LAKE. AIRMASS WILL STILL REMAIN SIMILARLY MILD UNDER BROAD RIDGING ALOFT. THIS APPEARS TO BE OVERDONE GIVEN PRESENCE OF MID/UPPER RIDGING AND MEAGER INSTABILITY. A COLD FRONT WILL SHIFT DOWN THE LAKE VERY LATE TONIGHT INTO EARLY SATURDAY MORNING.
321 PM MST FRI APR 17 2015 EXPECT CONTINUED ISOLATED RAIN AND HIGH ELEVATION SNOW SHOWERS THROUGH TONIGHT AS A LOW PRESSURE SYSTEM SITS NEAR THE FOUR CORNERS. EXPECT WARMER TEMPERATURES AND FEWER SHOWERS AS A DRIER WEATHER PATTERN SETS UP OVER THE REGION. THE COLD CLOSED LOW THAT HAS BROUGHT RAIN AND SNOW SHOWERS TO NORTHERN ARIZONA IS CURRENTLY SPINNING OVER COLORADO. A WEATHER DISTUBANCE ROTATING AROUND THE LOW WILL CONTINUE SHOWERS OVERNIGHT. THE UPPER LOW PUSHES EASTWARD AND THE CHANCES FOR PRECIPITATION DECREASE AS THE ATMOSPHERE WARMS AND DRIES.
SATELLITE AND RADAR LOOPS SHOW THE LOW CENTER ROUGHLY OVER WOLF CREEK PASS AT 3 PM MDT. OUR AREA HAS MAINLY BEEN IMPACTED BY MOISTURE AND ENERGY WRAPPING AROUND THE NORTH SIDE OF THIS LOW. THE CENTER OF THE LOW WILL SLOWLY TRACK INTO NORTHEAST CO BY SATURDAY AFTERNOON. ADDITIONAL MOISTURE/ENERGY WILL ROTATE AROUND THE LOW AND ACROSS OUR SIDE OF THE CONTINENTAL DIVIDE. THIS NORTHERN TROUGH WILL ACT AS THE KICKER FOR THE SLOW-MOVING COLORADO LOW. ALSO OF CONCERN FOR TONIGHT IS THE POSSIBILITY OF FREEZING TEMPERATURES IN SOME OF THE WESTERN CO VALLEYS. THEN GRAND JUNCTION AND NUCLA STAYED IN THE LOWER TO MID THIRTIES ALL DAY TODAY. TEMPERATURES COULD QUICKLY FALL BELOW FREEZING.
SOME OF THE COLDEST VALLEY LOCATIONS WILL APPROACH FREEZING AGAIN SATURDAY MORNING.
QUIET WEATHER WILL CONTINUE INTO TONIGHT BEFORE ANOTHER COLD FRONT MOVES ACROSS THE FORECAST AREA DURING THE DAY SATURDAY. AN UPPER LOW OVER COLORADO WILL ROTATE SOME CLOUDS NORTHWARD ACROSS FAR SOUTHEAST MONTANA BRINGING A SLIGHT CHANCE FOR A SHOWER AFTER MIDNIGHT. TEMPERATURES SATURDAY WILL BE COOLER WITH READINGS MAINLY IN THE LOWER 60S.
ADDITION PCPN LOOKS PROBABLE THEN SAT NIGHT/SUN MORNING ALONG A COLD FRONT SWEEPING THRU THE CWA.
334 PM CDT FRI APR 17 2015 LARGE-SCALE CUT OFF UPPER LOW CONTINUES TO CHURN OVER CO THIS AFTERNOON.
WE FIND A MORE ROBUST UPPER LOW OVER THE COLORADO FRONT RANGE WITH A FRONT EXTENDING SOUTH OVER THE TEXAS PANHANDLE TO DEL RIO. ALOFT THERE IS A LARGE ANTI-CYCLONE COVERING MUCH OF THE GULF OF MEXICO. THE ATLANTIC RIDGE AXIS IS WEAKENING ACROSS THE FLORIDA PENINSULA. EXPECT WIND SPEEDS TO FLUCTUATE DUE TO THE THERMAL TROUGH OVER THE MAINLAND AND CUBA PERTURBING THE SURFACE FLOW THROUGH SATURDAY. THE LARGE UPPER LOW COMPLEX MENTIONED ABOVE WILL GRADUALLY MOVE EASTWARD THROUGH THE WEEKEND.
Another round is forecast late this evening and overnight with another impulse rotating around the upper low and across eastern Kansas, and given additional lift from closer upper wave and a boost from the low level jet, think overnight is probably when the highest QPF will move through. On Saturday morning convection from the overnight hours will still be lingering across portions of eastern KS as the main mid/upper low finally begins to track over the plains. As the main mid/upper low progresses eastward it will gradually weaken into an open wave.
144 PM EDT FRI APR 17 2015 A WEAK COLD FRONT WILL MOVE ACROSS CENTRAL NEW YORK EARLY THIS AFTERNOON AND NORTHEAST PENNSYLVANIA BY LATE AFTERNOON. ANOTHER COLD FRONT WILL PASS ACROSS THE REGION SATURDAY.
HIGH PRESSURE WILL REMAIN OVER NORTHERN AND CENTRAL NEVADA THROUGH THE WEEKEND FOR DRY CONDITIONS AND A WARMING TREND DURING THE PERIOD.
TEMPERATURES GOT INTO THE LOWER 80S IN MANY AREAS THIS AFTERNOON. COULD BE A BIT OF SEVERE WEATHER ON THE FRONT END AS DRIER AIR MIXES DOWN WITH A GOOD BIT OF SHEAR IN THE LOWER LEVELS.
134 PM EDT FRI APR 17 2015 A WEAK COLD FRONT WILL PUSH THROUGH THE REMAINDER OF THE REGION TODAY. HIGH PRESSURE WILL BUILD IN BEHIND THE FRONT FOR TONIGHT AND WILL REMAIN OVER THE GREAT LAKES AND OHIO VALLEY ON SATURDAY.
A PACIFIC TROUGH WILL APPROACH THE WEST THROUGH THE AFTERNOON WITH CONVECTION DEVELOPING OVER THE WEST AND NORTH MOUNTAINS. AREAS OF HEAVIER PRECIPITATION WILL OCCUR OVER THE HIGHER MOUNTAINS. SATURDAY NIGHT THROUGH FRIDAY A SHORT WAVE DROPPING SOUTHEAST FROM FROM CANADA WILL FINALLY KICK OUR RESIDENT CLOSED LOW OUT INTO THE PLAINS.
633 PM EDT FRI APR 17 2015 HIGH PRESSURE WILL BUILD INTO THE AREA TONIGHT AND SATURDAY BEFORE MOVING OFF TO THE EAST ON SATURDAY NIGHT.
SHORT WAVE RIDGING WILL BRING IN SLIGHTLY DRIER AIR SUPPRESSING CONVECTION DURING THE MORNING HOURS. MOISTURE LEVELS WILL INCREASE DURING THE MID TO LATE AFTERNOON AS SEABREEZES DEVELOP AND MOVE INLAND IN CONCERT WITH WARM FRONT LIFTING TO THE NORTH LEADING TO SCATTERED SHOWERS/ISOLATED STORMS WITH BEST COVERAGE OF ACTIVITY. THERE WILL BE SOME LINGERING SHOWERS AND ISOLD TSTMS MAINLY DURING THE EARLY EVENING AS THE AFOREMENTIONED WARM FRONT MOVES INTO SE GA.
310 PM CDT FRI APR 17 2015 A COLD FRONT STRETCHED FROM LOW PRESSURE IN NORTHWEST ONTARIO INTO NORTHWEST MINNESOTA THIS AFTERNOON. THE FRONT WILL MOVE THROUGH THE NORTHLAND TONIGHT WITH HIGH PRESSURE NOSING INTO THE REGION. THE HIGH WILL MOVE EAST OF THE REGION ON SATURDAY AS A TROUGH OF LOW PRESSURE LIFTS INTO THE EASTERN DAKOTAS. EASTERLY WINDS OFF OF LAKE SUPERIOR WILL KEEP AREAS ALONG THE LAKE MUCH COOLER THAN AREAS INLAND.
MID TO UPPER LEVEL RIDGING ARRIVES ON EARLY SATURDAY AS NELY LOW LEVEL FLOW DRIES THE ATMO OUT TEMPORARILY. DESPITE SOME EARLY SUNSHINE, HAVE GONE CLOSER TO THE COOLER GFS MOS TEMPS.
A RELATIVELY WEAK TO MODERATE BOUYANCY/CAPE BUT HIGH SHEAR ENVIRONMENT IS SET UP FOR THIS AFTERNOON WITH A STATIONARY BOUNDARY SEPARATING A MOIST A COOLER AIRMASS ACROSS NORTHERN KANSAS AND DRYER WARMER AIR BEHIND A DRYLINE WEST OF LIBERAL. AS THE UPPER LOW OVERSPREADS THE AREA INTO SATURDAY MORNING, THE WARM/MOIST CONVEYOR BELT REGIONS WILL BE MOST LIKELY ACROSS THE NORTHERN AND EASTERN SECTIONS OF THE FORECAST AREA, BY CONSENSUS OF THE MODELS. HERE AN ADDITIONAL QUARTER TO LESS THAN AN INCH OF RAIN MAY OCCUR TROUGH SATURDAY MORNING. THE VERY SLOW MOVING UPPER LOW WILL CONTINUE TO PROVIDE CHANCES FOR PRECIPITATION UNTIL IT FINALLY CLEARS THE REGION.
638 PM EDT FRI APR 17 2015 HIGH PRESSURE WILL SETTLE OVER SOUTHEASTERN OHIO TONIGHT THEN A STRONGER AREA OF HIGH PRESSURE IS EXPECTED TO RIDGE INTO THE AREA FROM CENTRAL ONTARIO.
Otherwise, showers and thunderstorms are possible across all of West Central Texas tonight and tomorrow, as the upper low, centered over extreme northwestern New Mexico this afternoon, moves slowly toward the northeast.
/ISSUED 305 PM CDT FRI APR 17 2015/ UPPER LEVEL LOW CURRENTLY SPINNING OVER NORTHERN NEW MEXICO/SOUTHERN COLORADO WILL BE THE DRIVING FORCE BEHIND THE WEATHER ACROSS EASTERN OKLAHOMA AND WESTERN ARKANSAS THIS WEEKEND. WITH PACIFIC MOISTURE BEING ENTRAINED TO THE FLOW AROUND THE UPPER LEVEL LOW.
SHORT TERM: (Through Late Tonight) A weak upper level RIDGE continues to persist overhead this afternoon with a vigorous upper LOW spinning over southern CO. Have only had to make minimal changes to previous forecast, but backed off on the low chances a bit further, limiting them to only some sections of northeast and central MO and to just the hours immediately preceding dawn. Temps look to be a bit warmer than persistence with what should be increasing clouds from the west late and a bit stronger southeast flow but many areas should still get into the 50s, albeit only briefly, before sunrise. Otherwise, will see highs in the low to mid 70s with coolest temps over central MO due to the cloud cover and precipitation.
AN UPPER RIDGE WILL PROVIDE FAIR WEATHER SATURDAY.
THE CLOSED LOW OVER THE MOUNTAIN WEST FINALLY BEGINS TO EJECT TO THE EAST WITH UPPER LEVEL FLOW BECOMING MORE SOUTHWESTERLY.
WENT AHEAD AND CANCELLED THE HIGH WIND WARNING EARLY AS A RESULT. INCREASED POP FOR RAIN SHOWERS FURTHER WEST INTO THE LARAMIE RANGE AS MODELS HAVE TRENDED A BIT FURTHER WEST WITH THE SURFACE COLD FRONT SLIDING SOUTHWARD ACROSS THE HIGH PLAINS. THURSDAY LOOKS LIKE A PLEASANT DAY WITH HIGHS IN THE MID 50S TO MID 60S AS ANOTHER RAPIDLY MOVING LOW AMPLITUDE RIDGE AXIS MOVES ACROSS THE AREA.
RESULTING IN SLIGHTLY WARMER TEMPS IN THE WEST OVERNIGHT.
OTHERWISE VERY DRY AIR IS NOTED ON 00Z JAX SOUNDING IN THE WAKE OF THE COLD FRONT WED MORNING. WITH BIT WARMER TEMPS NEAR THE COAST AS LLVL FLOW TURNS NNE. LIGHT NLY WINDS TONIGHT WILL TURN TO NE THU MORNING THEN SE TO SLY NEAR 10 KT AFTER 17Z THU AHEAD OF AN APPROACHING COLD FRONT.
THIS WILL LEAD TO RATHER VARIABLE DIRECTIONS AT MOST SITES PRIOR TO THE ARRIVAL OF A COLD FRONT OVERNIGHT. /ISSUED 919 PM CST WED MAR 2 2016/ THUNDERSTORMS HAVE FORMED A BAND EAST-WEST ACROSS CENTRAL OKLAHOMA AS THE UPPER TROUGH INTERSECTS HIGHER LOWER LEVEL MOISTURE ACROSS CENTRAL OKLAHOMA.

527 PM CST WED MAR 2 2016 FOR 00Z TAFS /ISSUED 256 PM CST WED MAR 2 2016/ A LARGE AREA OF HIGH PRESSURE WAS SITUATED ACROSS THE LOWER OHIO AND TENNESSEE VALLEY AT 20Z WITH MOSTLY SUNNY SKIES CONTINUING ACROSS THE AREA. TEMPS ACROSS THE REGION WERE ONLY RANGING FROM THE LOWER 40S ACROSS SOUTHERN MIDDLE TENNESSEE TO THE MID TO UPPER 40S ACROSS NORTHERN ALABAMA. AN AREA OF LOW PRESSURE NOW ACROSS THE CENTRAL PLAINS STATES WILL SHIFT EASTWARD INTO THE MISSOURI VALLEY REGION BY 12Z THURSDAY.
INCREASED POP FOR RAIN SHOWERS FURTHER WEST INTO THE LARAMIE RANGE AS MODELS HAVE TRENDED A BIT FURTHER WEST WITH THE SURFACE COLD FRONT SLIDING SOUTHWARD ACROSS THE HIGH PLAINS. THURSDAY LOOKS LIKE A PLEASANT DAY WITH HIGHS IN THE MID 50S TO MID 60S AS ANOTHER RAPIDLY MOVING LOW AMPLITUDE RIDGE AXIS MOVES ACROSS THE AREA.

1249 AM EST THU MAR 3 2016 HIGH PRESSURE WILL BUILD IN THROUGH THURSDAY.
A MAINLY CLEAR SKY WAS FOUND ALONG THE INTERNATIONAL BORDER DUE TO THE DRY AIR FROM THE HIGH. THE RIDGE AXIS ALONG THE NORTH SHORE HAS PRECLUDED ANY GRAVITY WAVE TYPE LIGHT SNOW FROM FORMING AND HAVE REMOVED THIS AS WELL. AN APPROACHING 850HPA TROUGH IN THE DAKOTAS HAS BROUGHT A RETURN FLOW AND INCREASING MID LEVEL TEMPERATURES INTO NORTH CENTRAL MINNESOTA. THE SURFACE BOUNDARY WILL TRANSITION INTO A WEAK COLD FRONT AS IT TRACKS EAST ACROSS THE REGION THURSDAY. HIGH PRESSURE WILL BUILD INTO NORTHWEST MINNESOTA BRINGING CLEARING SKIES AND LIGHT WINDS.
SHORT WAVE TROUGH BUILDS INTO THE SOUTHERN APPALACHIAN REGION LATE THIS MORNING THROUGH LATE TONIGHT.

Also trended warmer with overnight temperatures in the east, with most places not likely to drop much from current levels, unless there is enough precipitation to wet bulb which is unlikely. Instability parameters keep thunder chances just outside (mainly south) of PAH FA thru the event, but with the surface/upper Low tracks across the FA, wouldnt be shocked to see an isolated stroke.
403 PM CST WED MAR 2 2016 AN APPROACHING 850HPA TROUGH IN THE DAKOTAS HAS BROUGHT A RETURN FLOW AND INCREASING MID LEVEL TEMPERATURES INTO NORTH CENTRAL MINNESOTA. THE SURFACE BOUNDARY WILL TRANSITION INTO A WEAK COLD FRONT AS IT TRACKS EAST ACROSS THE REGION THURSDAY. HIGH PRESSURE WILL BUILD INTO NORTHWEST MINNESOTA BRINGING CLEARING SKIES AND LIGHT WINDS.
SURFACE ANALYSIS THIS EVENING DEPICTS TWO DISTINCT LOW PRESSURE CENTERS IN PLACE ACROSS THE CENTRAL CONUS. FOR THE WEATHER GRIDS ON THURSDAY MORNING AND AFTERNOON, FORECAST SOUNDINGS AT THE ONSET OF PRECIP INDICATE THAT BELOW 700MB THE PROFILE WILL BE AT TO JUST ABOVE FREEZING. AS PRECIP BEGINS TO FALL INTO THE LOWEST LAYERS WHERE THE DRY AIR EXISTS, EXPECT TEMPS TO COOL SLIGHTLY AS THESE LEVELS BEGIN TO SATURATE.
