1137 AM CST FRI JAN 29 2016 FOR 18Z TAFS /ISSUED 1039 AM CST FRI JAN 29 2016/ UPPER LEVEL RIDGING IS BEGINNING TO BUILD INTO THE FORECAST AREA. NORTHWESTERLY WINDS WILL BACK TO BECOME SOUTHERLY AND LIGHT TONIGHT AS HIGH PRESSURE DOMINATES THE REGION.
1035 AM CST FRI JAN 29 2016 UPPER-LEVEL RIDGE REMAINS IN PLACE TODAY ALLOWING FOR MOSTLY CLEAR SKIES AREAWIDE.
A PRESSURE RIDGE WILL EXTENDING THROUGH THE FORECAST AREA TONIGHT WILL MOVE OFF THE SOUTHEAST COAST SATURDAY.
A COMPACT TROUGH WAS DIVING SOUTHEAST FROM THE PALMER DIVIDE INTO WESTERN KANSAS WITH A COLD FRONT ABOUT 100 MILES IN ITS ADVANCE. THE MOST PROMINENT LOW LEVEL THERMAL RIDGE AHEAD OF THIS FRONT WAS SHARPENING ALONG A MORTON-LUBBOCK-ALTUS LINE AS OF 19Z COINCIDENT WITH AN AXIS OF LOW RH VALUES /AS LOW AS 5 PERCENT/ AND ENHANCED WESTERLY WINDS. AS THE AFOREMENTIONED COLD FRONT ARRIVES THIS EVENING. THE TRAILING PRESSURE RIDGE WILL BE SHUNTED EAST AS THE FLOW TURNS FROM NW-W.
THIS DOESNT APPEAR TO BE CHANGING EITHER AS WINDS REMAIN WESTERLY IN THE LOW LEVELS THROUGH THE WEEKEND.
610 PM EST FRI JAN 29 2016 AVIATION SECTION HAS BEEN UPDATED BELOW ONE LOW PRESSURE SYSTEM WILL BRING RAIN TO CENTRAL INDIANA LATER THIS WEEKEND.
/ISSUED 1035 AM CST FRI JAN 29 2016/ UPPER-LEVEL RIDGE REMAINS IN PLACE TODAY ALLOWING FOR MOSTLY CLEAR SKIES AREAWIDE.
THE AREA OF FORCING AHEAD OF THE UPPER LEVEL TROUGH/VORT MAX AND PRECIPITATION WILL SPREAD EAST OVER THE NORTHLAND THROUGH THE NIGHT. OR WILL REMAIN MIX WITH SLEET/FREEZING RAIN FOR THE EVENING.
Clear skies, light winds, and dry conditions under deep layer ridging will allow temperatures to fall into the upper 30s away from the coast.
717 PM EST FRI JAN 29 2016 HIGH PRESSURE CONTINUES TO BUILD INTO THE FLORIDA PENINSULA FROM THEN NORTH ALLOWING FOR THE WINDS TO CONTINUE TO DECREASE AND BECOME LIGHT AND VARIABLE TONIGHT OVER THE LAND AREAS.
Our region will reside to the west of the trough axis, giving us downsloping, southwesterly winds.
High pressure over the Appalachians will move off the East Coast tomorrow, putting the Ohio and Tennessee Valleys into warm southerly flow.
OVERNIGHT A WARM FRONT WILL LIFT ACROSS THE AREA AND 850 TEMPS RISE TO 7 TO 9 C. TOMORROW THE NEXT DISTURBANCE WILL RIDE ACROSS THE CENTRAL ROCKIES AND PUSH ONTO THE HIGH PLAINS FOR THE AFTERNOON. HAVE GONE WITH THE WARMER MAV/EC GUIDANCE AS THE PAST SEVERAL DAYS WE HAVE BEEN MORE OFTEN THAN NOT ABLE TO BE AT OR WARMER THAN THE WARM MAV/EC GUIDANCE. SOME DRY AIR INITIALLY IN THE LOWER LEVELS WILL LIMIT PRECIP REACHING THE GROUND. BEHIND A SURFACE COLD FRONT.
556 PM EST FRI JAN 29 2016 A NARROW RIDGE OF HIGH PRESSURE WILL BUILD IN FROM THE WEST TONIGHT AND WILL CREST OVER THE REGION EARLY SATURDAY BEFORE SHIFTING OFFSHORE. A WEAK WARM FRONT WILL LIFT INTO THE REGION SATURDAY AFTERNOON AND WILL PUSH NORTHEAST OF THE REGION SATURDAY NIGHT.

Warm conditions will continue Saturday, with highs in the low to mid 60s for most.
/ISSUED / A NICE QUIET WEATHER PATTERN WILL PREVAIL THROUGH THE SHORT TERM AS A DRY NORTHWEST FLOW BECOMES ESTABLISHED TODAY IN THE WAKE OF A DEPARTING UPPER LEVEL TROUGH TO THE EAST. RADIATIONAL COOLING WILL ALLOW LOWS TO DIP AT OR BELOW FREEZING ACROSS MUCH OF NORTH GA TONIGHT.
18A SFC DATA HAS HIGH PRESSURE RUNNING FROM THE GULF COAST INTO LOWER MICHIGAN. A WEAK LOW WAS IN SOUTHWEST KANSAS WHILE A WARM FRONT RAN FROM THE EASTERN DAKOTAS INTO THE TENNESSEE VALLEY. QUIET AND DRY CONDITIONS WILL CONTINUE THROUGH SUNSET AND OVERNIGHT AS HIGH PRESSURE MOVES INTO THE OHIO VALLEY.
A WINTRY MIX OF FREEZING RAIN WAS REPORTED NEAR BURNS AND SNOW EXTENDED ACROSS BAKER VALLEY. THE LOWER TREASURE VALLEY WAS IN A COLD POOL OF AIR THAT EXTENDS NORTH THROUGH COUNCIL. EXPECT SNOW TO CHANGE TO A PERIOD OF RAIN LATER TODAY BELOW 4000 FEET NORTH TO 5000 FEET SOUTH AHEAD OF A SHARP COLD FRONT.
MOVED OUT OF THE AREA AS HIGH PRESSURE SNEAKED INTO THE AREA FROM THE NORTH. HOWEVER WITH HIGH PRESSURE IN PLACE. MOST GUIDANCE APPEARS TO BE HINTING AT COOLER TEMPS. THE ECMWF SEEMS TO BE THE HIGHER OF MOST OF THE MODELS.
SFC TROF WILL SLIDE SEWD TODAY. A LEESIDE SFC TROF OF LOW PRESSURE WILL ORGANIZE OVER ERN CO AND NERN NM AS UPPER LEVEL QUASI ZONAL FLOW PREVAILS.
TEMPERATURES ON SATURDAY TO CLIMB INTO THE LOW TO MID 70S WITH SOUTHERLY WINDS FORECAST TO APPROACH LAKE WIND ADVISORY CRITERIA.
UPDATED TO DISCUSS FREEZING RAIN THREAT AND ADJUST THE AVIATION DISCUSSION. A STRONG COLD FRONT WILL SWEEP SOUTH THROUGH UTAH LATE TONIGHT THROUGH SATURDAY.
WARM FRONT CONTINUES TO TRACK EAST ACROSS THE EASTERN CWA WITH INCREASING WESTERLY WINDS AND MODEST TEMP RISES IN ITS WAKE. TEMPERATURES STAY ABOVE NORMAL THROUGH THE WEEKEND BUT ARE EXPECTED TO BE A BIT COOLER THAN WHAT WAS OBSERVED ON FRIDAY.
ONE LOW PRESSURE SYSTEM WILL BRING RAIN TO CENTRAL INDIANA LATER THIS WEEKEND.
WARM FRONT CONTINUES TO ADVANCE EASTWARD ACROSS THE CWA AND HAS PASSED THE MISSOURI VALLEY. PIR AND MBG HAVE NORTHWEST WINDS AND TEMPS IN THE LOW 40S. STILL EXPECTING A DECENT CHANCE FOR SOME LIGHT RAIN IN RESPONSE TO THE UPPER LEVEL TROUGH.
A DRY COLD FRONT WILL CROSS CENTRAL NC TODAY. HIGH PRESSURE WILL BUILD OVERHEAD TONIGHT THEN DRIFT OFFSHORE SATURDAY. THIS HIGH WILL REMAIN ANCHORED OFF THE SE U.
Southerly winds will lead to warmer temperatures tonight through the weekend.
WEAK TROUGH THAT MOVED ACROSS CENTRAL/SOUTHWEST MT LAST NIGHT HAS MOVED INTO EASTERN MT, LEAVING A MIX OF CLEAR SKIES AND SCT/BKN MID- LEVEL CLOUDS ACROSS THE REGION. CURRENT BREEZY WINDS (GUSTS 20-30 KTS) ACROSS THE REGION WILL CONTINUE THROUGH LATE MORNING THEN DECREASE AS SURFACE PRESSURE GRADIENT WEAKENS BEHIND THE DEPARTING TROUGH.
An upper trough and and associated surface front were crossing central Nebraska and approaching central Kansas this afternoon. While winds are gusty from the northwest behind this front, temperatures in its wake were not much colder than ahead of it due to downslope warming off the Rockies and warm advection from the northwest in the low levels.
Upper level heights will also be rising as an upper level ridge moves eastward into our area later today.
/ISSUED 455 AM CST FRI JAN 29 2016/ SHORT WAVE ALOFT PASSING FROM COLORADO AND WYOMING INTO THE PLAINS THIS MORNING IS WORKING TO FLATTEN THE UPPER RIDGE AND TIGHTEN WIND GRADIENTS ALOFT OVER THE REGION.
HIGH PRESSURE REMAINS LOCATED OFF THE SOUTH TEXAS COAST AND IS FORECAST TO MOVE OFF TO THE EAST WITH THE CENTER OF THE ANTICYCLONE OVER THE SOUTHEAST UNITED STATES BY EARLY SATURDAY MORNING AND THEN OVER THE WESTERN ATLANTIC BY THE END OF THE PERIOD. WEAK LOW PRESSURE WILL MOVE INTO CENTRAL MISSOURI AND DRAG A DECAYING FRONTAL BOUNDARY THROUGH THE STATE SATURDAY NIGHT.
Progressive upper pattern will transition from NW flow today to flat ridging by late Saturday. Low-level thermal trof currently over the Lower Ohio Valley will scoot fairly quickly to the east.
1003 AM PST FRI JAN 29 2016 WARM AND DRY TODAY UNDER WEAKENING HIGH PRESSURE.
A WEAK COLD FRONT AND ASSOCIATED PRESSURE RISE BUBBLE IS TRACKING FROM CENTRAL INTO EASTERN NORTH DAKOTA. WITH WARM TEMPERATURES ALOFT AND NEAR FREEZING TO SUB- FREEZING SURFACE TEMPERATURES THERE IS A PROBABILITY OF SOME MIXED PRECIPITATION BEGINNING IN THE WEST LATE TONIGHT. BUT THE THREAT OF LIGHT FREEZING PRECIPITATION WILL EXIST ALONG THE LEADING EDGE OF PRECIPITATION. A RAIN SNOW MIX IN THE MORNING WILL SHIFT TO ALL RAIN IN THE AFTERNOON AS TEMPERATURES RISE ABOVE FREEZING. EVEN LIGHT AMOUNTS OF FREEZING RAIN CAN CAUSE HAZARDOUS TRAVEL CONDITIONS. NO HAZARDS EXPECTED BUT WILL ADD A MENTION OF FREEZING RAIN IN THE HWO.
328 PM EST FRI JAN 29 2016 HIGH PRESSURE WILL BUILD IN FROM THE WEST TONIGHT.
SHORT TERM: (Through Late Tonight) Weak cold front will wash out as it moves into the CWA overnight tonight.
1131 AM CST FRI JAN 29 2016 The pattern across the Nation this morning is dominated by a messy progressive split flow with a significant trough axis to our east. However, despite the northwest flow aloft from the trough to our east, winds from the mid to lower levels have generally been prevailing from the south thanks to the split flow, helping lift temperatures above normal this past week. This trend will persist for another couple of days even as a weak cold front moves through. As for Saturday, despite the cold front Friday evening, temperatures Saturday will likely be similar to today's as the split flow pattern allows little cold to spill south.
A SMALL AREA OF RAIN/SNOW/FREEZING RAIN WILL BE POSSIBLE IN THE HAVRE AREA AROUND 10Z SAT.
316 PM CST FRI JAN 29 2016 WARM FRONT CONTINUES TO TRACK EAST ACROSS THE EASTERN CWA WITH INCREASING WESTERLY WINDS AND MODEST TEMP RISES IN ITS WAKE. TEMPERATURES STAY ABOVE NORMAL THROUGH THE WEEKEND BUT ARE EXPECTED TO BE A BIT COOLER THAN WHAT WAS OBSERVED ON FRIDAY.
AS AN UPPER LEVEL TROUGH CENTERED TO THE NORTH MOVES INLAND AND VERY COLD AIR ALOFT MOVES INTO THE AREA, SHOWERS WILL SPREAD INLAND FROM THE NORTHWEST AND SNOW LEVELS WILL LOWER.
HIGH PRESSURE AT THE SURFACE WILL SLIDE EAST TONIGHT. SOUTHERN DISTURBANCE MENTIONED ABOVE WILL BE THE ONLY DETRIMENT TO ZONAL FLOW ALOFT BEFORE INCREASING SOUTHWESTERLY FLOW DEVELOPS DOWNSTREAM OF AN UPPER TROUGH DIGGING INTO THE NORTHERN GREAT PLAINS. ABOVE NORMAL TEMPERATURES INTO THE 50S WILL RESULT FOR THE FIRST HALF OF THE WEEKEND GIVEN THE WARMER AIR ALOFT AND ONLY CLOUDS BEING OF THE MID-HIGH VARIETY.
VFR conditions will continue despite the passage of a weak cold front overnight. Cooler.
THUS TEMPERATURES WILL BE WARMER IN THE MID/UPPER 60S OVER MUCH OF THE AREA. CLEAR SKIES WILL CONTINUE TONIGHT WITH WARMER OVERNIGHT LOWS. THE NICE WEEKEND WILL CONTINUE ON SATURDAY AS STRONG SURFACE RIDGING PREVAILS. EXPECT MOSTLY SUNNY SKIES AND SPRING LIKE TEMPERATURES IN THE LOW 70S OVER MOST OF THE AREA. LITTLE WILL CHANGE SATURDAY NIGHT WITH WARMER OVERNIGHT LOWS ONCE AGAIN.
Weak surface ridging returns tonight, with weakening winds and some passing cirrus still allowing for lows to drop back into the upper 20s to mid 30s. Saturday is still shaping up to be another warm day with good warm advection evident on models ahead of an approaching upper trough.
242 PM EST FRI JAN 29 2016 A NARROW RIDGE OF HIGH PRESSURE WILL BUILD IN FROM THE WEST TONIGHT AND WILL CREST OVER THE REGION EARLY SATURDAY BEFORE SHIFTING OFFSHORE. A WEAK WARM FRONT WILL LIFT INTO THE REGION SATURDAY AFTERNOON AND WILL PUSH NORTHEAST OF THE REGION SATURDAY NIGHT.
THE LATEST RADAR SHOWED A FEW SHOWERS MOVING INTO PORTIONS OF THE LOWER COLUMBIA BASIN AND FOOTHILLS OF THE BLUE MOUNTAINS.
213 PM CST FRI JAN 29 2016 18A SFC DATA HAS HIGH PRESSURE RUNNING FROM THE GULF COAST INTO LOWER MICHIGAN. A WEAK LOW WAS IN SOUTHWEST KANSAS WHILE A WARM FRONT RAN FROM THE EASTERN DAKOTAS INTO THE TENNESSEE VALLEY. QUIET AND DRY CONDITIONS WILL CONTINUE THROUGH SUNSET AND OVERNIGHT AS HIGH PRESSURE MOVES INTO THE OHIO VALLEY.
WINDS STARTING TO INCREASE AS EXPECTED ACROSS WIND PRONE LOCALES WITH GUSTS NEAR 55 MPH AT HALLECK RIDGE NEAR ELK MOUNTAIN AND 40 TO 50 MPH AT BORDEAUX. GFS PROGS A 50 TO 60 KNOT 700 MB WIND MAX TODAY ACROSS THE HIGH WIND WARNING AREA WITH AROUND 60 METERS OF 700 MB HEIGHT DIFFERENCE FROM CRAIG TO CASPER. COLD FRONT AND BAROCLINIC BAND MOVE ACROSS OUR COUNTIES AND WITH MODERATE DYNAMICS AND MOISTURE. CHANCE OF SNOW AS THE MAIN TROUGH AXIS MOVES OVERHEAD.
Although winds will be lighter than this afternoon, they will be a few mph stronger than last night, resulting in just enough mixing to keep temperatures warmer than freezing for lows across most of the area tonight. Temperatures will be a few degrees warmer than today with lower 80s possible for parts of the area and afternoon winds of 15 to 20 mph with gusts to around 30 mph.
1146 AM CST FRI JAN 29 2016 MERIDIONAL MID/UPPER FLOW PATTERN THIS MORNING FEATURING AMPLIFIED RIDGING ALONG THE MISSISSIPPI VALLEY AND SHARP TROUGHING OVER THE NORTHERN/CENTRAL HIGH PLAINS. WARM ADVECTION ON THE LEADING EDGE OF THE LOW-LEVEL RIDGE WAS CONTRIBUTING TO LIGHT RETURNS ON AREA RADARS TO OUR NORTH. EXPECT STEADY TEMPERATURES THIS EVENING INTO TONIGHT WITH THERMAL RIDGE SHIFTING EAST AND A 50 KNOT LOW-LEVEL JET TRANSPORTING ADDITIONAL WARMTH AND LOW-LEVEL MOISTURE INTO SOUTHERN WISCONSIN. MODEL FORECAST SOUNDINGS SHOW A NEAR SATURATION OF THE LOW-LEVELS LATER TONIGHT SO EXPECT WIDESPREAD STRATUS TO DEVELOP.
405 PM EST FRI JAN 29 2016 WARMER TEMPERATURES WILL QUICKLY RETURN THIS WEEKEND.
UPPER LEVEL FLOW AND IR SAT IMAGERY SHOWED THE TROUGH JUST OFF THE EAST COAST. SOUTHWEST TO SOUTH FLOW WILL BECOME ESTABLISHED OVER THE LOWER MISSISSIPPI VALLEY BY MID DAY SATURDAY.
333 PM EST FRI JAN 29 2016 THE AVIATION SECTION HAS BEEN UPDATED BELOW ONE LOW PRESSURE SYSTEM WILL BRING RAIN TO CENTRAL INDIANA LATER THIS WEEKEND.
238 PM CST FRI JAN 29 2016 UPPER LEVEL LOW PRESSURE OVER MONTANA WILL WORK ACROSS THE NORTHERN PLAINS TODAY. AS IS TYPICAL FOR THIS TIME OF THE YEAR THE LOWER LEVELS REMAIN PRETTY DRY SO THE CHALLENGE IS TO GET SOME OF THE MID LEVEL MOISTURE AND LIFT TO GENERATE ENOUGH PRECIPITATION TO FALL THROUGH THIS DRY LAYER. BY TONIGHT A WEAK RIDGE OF HIGH PRESSURE WILL WORK INTO THE AREA BUT NOT EXPECTING FLOW TO COMPLETELY DROP OFF FOR MULTIPLE HOURS SO LOWS WILL BE PRETTY MILD.
1251 PM EST FRI JAN 29 2016 HIGH PRESSURE WILL QUICKLY SLIDE ACROSS THE REGION THIS AFTERNOON AND INTO THE MID ATLANTIC REGION BY SATURDAY MORNING. SOUTHWEST FLOW BEHIND THIS DEPARTING HIGH PRESSURE WILL LEAD TO WARMER TEMPERATURES FOR THE WEEKEND.
WATER VAPOR IMAGERY SHOWS A SHORT WAVE TROUGH MOVING THROUGH THE CENTRAL ROCKIES WITH A VORTICITY MAXIMUM MOVING ACROSS THE NORTHERN GULF OF CALIFORNIA. THE SHORT WAVE TROUGH WILL MOVE EAST INTO THE CENTRAL PLAINS TODAY WITH AN AREA OF LOW PRESSURE FORMING OVER THE SOUTHERN HIGH PLAINS OF WEST TEXAS.
HIGH PRESSURE WILL BRING DRY AND MILD WEATHER TO NORTHERN ARIZONA THROUGH SATURDAY.
1051 AM CST FRI JAN 29 2016 WARM FRONT CONTINUES TO ADVANCE EASTWARD ACROSS THE CWA AND HAS PASSED THE MISSOURI VALLEY. PIR AND MBG HAVE NORTHWEST WINDS AND TEMPS IN THE LOW 40S. STILL EXPECTING A DECENT CHANCE FOR SOME LIGHT RAIN IN RESPONSE TO THE UPPER LEVEL TROUGH.
WEAK HIGH PRESSURE OVER THE WESTERN GULF HELPING WITH SW FLOW THROUGH THE AREA TERMINALS THIS MORNING AND AFTERNOON BEFORE BECOMING MORE SOUTHERN LATE THIS AFTERNOON. SOUTHWEST WINDS ON THE BACKSIDE OF THE HIGH HAD RETURNED AND A GRADUAL INCREASE IN WIND SPEEDS IS EXPECTED TODAY.
717 PM EST FRI JAN 29 2016 HIGH PRESSURE WILL MOVE EAST ACROSS THE OHIO VALLEY TONIGHT. A WARM FRONT DEVELOPING OVER THE MISSISSIPPI VALLEY WILL LIFT NORTHEAST ACROSS THE GREAT LAKES ON SATURDAY.
GIVEN ALL THIS DID OPT TO DROP VALLEY TEMPS GIVEN SNOW PACK IN AREAS THAT SEE LITTLE IF ANY SUN AND EVEN IF THE HIGH IS EAST OVERALL THE WAA WILL BE WEAK. THEREFORE THINK VALLEY LOCALES WILL SEE TEMPS DROPPING INTO THE LOWER 20S AT LEAST. HIGH PRESSURE AT THE SURFACE WILL SLIDE EAST TONIGHT. SOUTHERN DISTURBANCE MENTIONED ABOVE WILL BE THE ONLY DETRIMENT TO ZONAL FLOW ALOFT BEFORE INCREASING SOUTHWESTERLY FLOW DEVELOPS DOWNSTREAM OF AN UPPER TROUGH DIGGING INTO THE NORTHERN GREAT PLAINS. ABOVE NORMAL TEMPERATURES INTO THE 50S WILL RESULT FOR THE FIRST HALF OF THE WEEKEND GIVEN THE WARMER AIR ALOFT AND ONLY CLOUDS BEING OF THE MID-HIGH VARIETY.
SOUTHWEST WINDS ON THE BACKSIDE OF THE HIGH HAD RETURNED AND A GRADUAL INCREASE IN WIND SPEEDS IS EXPECTED TODAY.
339 PM CST FRI JAN 29 2016 WARMER TEMPS ARE ON THEIR WAY TO THE REGION AS UPPER RIDGING WILL BUILD IN.
SAT MAXES SHOULD REACH INTO THE UPPER 30S NORTH AND THE LOWER 40S SOUTH.
1113 AM CST FRI JAN 29 2016 HIGH PRESSURE AND LIGHT WINDS IN PLACE INITIALLY FOR THE TERMINALS.
LOW PRESSURE TROUGH WILL REACH THE MID MISSOURI VALLEY BY LATE THIS AFTERNOON. SOME UPPER LEVEL KINEMATIC FORCING WILL ACCOMPANY THE TROUGH.
A TROUGH HAS MADE ITS WAY ACROSS MOST OF THE FORECAST AREA WITH A COLD FRONT NOW MOVING THROUGH NORTHWEST ND. EARLY THIS MORNING A WARM FRONT BISECTED THE STATE AHEAD OF AN UPPER LEVEL SHORT WAVE EVIDENT IN WATER VAPOR OVER CENTRAL MONTANA.
WARMER TEMPS ARE ON THEIR WAY TO THE REGION AS UPPER RIDGING WILL BUILD IN.
THIS WILL DISLODGE THE LEE TROUGH AND SEND IT TOWARD NORTH TEXAS. THIS WILL INDUCE ANOTHER LEE TROUGH.
648 PM EST FRI JAN 29 2016 A PRESSURE RIDGE WILL EXTENDING THROUGH THE FORECAST AREA TONIGHT WILL MOVE OFF THE SOUTHEAST COAST SATURDAY.
109 PM EST FRI JAN 29 2016 SNOW SHOWERS ARE EXPECTED TO DEVELOP ACROSS PORTIONS OF CENTRAL NEW YORK AND NORTHEAST PENNSYLVANIA TODAY AS A COLD FRONT MOVES ACROSS THE REGION. A COLD FRONT IS PUSHING ITS WAY ACROSS WESTERN PA/NY THIS MORNING AND VERY LIGHT SNOW SHOWERS ARE OCCURRING AHEAD OF THIS BOUNDARY. SHOWERS OVER THE REGION WILL SLOWLY WIND DOWN LATE TONIGHT AS RIDGING AT THE SFC AND ALOFT BUILD INTO NORTHEAST PA AND CENTRAL NY AND TEMPS ALOFT RISE. BY SAT AFTERNOON 850MB TEMPS WILL RISE ABOVE FREEZING AND THERE WILL BE A CHANCE FOR A MIX OF RAIN/SNOW.
HIGH PRESSURE WILL BUILD EAST ACROSS THE AREA TONIGHT INTO SATURDAY. THE HIGH WILL MOVE EAST OF THE AREA SATURDAY WITH SOUTHERLY FLOW DEVELOPING.
341 PM EST FRI JAN 29 2016 HIGH PRESSURE WILL BUILD OVER THE REGION TONIGHT THROUGH SATURDAY.
1209 PM EST FRI JAN 29 2016 SNOW SHOWERS ARE EXPECTED TO DEVELOP ACROSS PORTIONS OF CENTRAL NEW YORK AND NORTHEAST PENNSYLVANIA TODAY AS A COLD FRONT MOVES ACROSS THE REGION.

THE COLD FRONT/BOUNDARY SETS UP SOMEWHERE OVERHEAD AS THE BIG SUBTROPICAL RIDGE HOLDS IT UP. MAXES ON THURSDAY WILL TAKE A RUN AT 90F IN THE LOWER ELEVATIONS IN THE SE WITH 80S ELSEWHERE.
1155 PM CDT Wed Jun 10 2015 A weak convergence zone in the low levels of the atmosphere along with a mid-level wave/moisture maxima were just enough to get isolated showers and thunderstorms going today over portions of western Missouri. Models do indicate a weak short wave trough/vorticity lobe sliding out of eastern Kansas into western Missouri by Thursday afternoon. Temperatures on Thursday will be about the same, if not a degree or so warmer than today.

626 PM CDT WED JUN 10 2015 A WEAKNESS IN THE HIGH PRESSURE RIDGE ALOFT WILL LINGER ALONG THE GULF COAST AND SOUTHEASTERN STATES OVER THE NEXT COUPLE OF DAYS. BUT SUBSIDENCE FROM THE RIDGE OVERHEAD WILL SUPPRESS MOST ACTIVITY. THE PRESSURE GRADIENT WILL INTENSIFY OVER THE NEXT 12 TO 24 HOURS AS LEE ROCKIES TROUGHING TAKES PLACE IN RESPONSE TO A WEST COAST UPPER TROUGH. THE RIDGE AXIS IS APPROACHING THE AREA BUT WILL LIKELY START SEEING THE INFLUENCE OF A STRONG UPPER TROUGH CURRENTLY APPROACHING SOUTHERN CALIFORNIA. THIS UPPER TROUGH WILL MOVE EAST INTO THE 4-CORNERS REGION DURING THE DAY TOMORROW INDUCING SURFACE PRESSURE FALLS IN THE LEE OF THE ROCKIES. THE CENTER OF THE RIDGE AXIS WILL STILL BE ACROSS NORTH TEXAS TOMORROW AFTERNOON BUT HEIGHTS WILL BE SLIGHTLY LOWER AS THE UPPER TROUGH GET CLOSER.
A weak convergence zone in the low levels of the atmosphere along with a mid-level wave/moisture maxima were just enough to get isolated showers and thunderstorms going today over portions of western Missouri.
