Aikyam-Lab/Synoptic-Bench huggingface dataset:
GENERALLY DRY WEATHER AND WELL ABV NORMAL TEMPS ARE ANTICIPATED FOR TODAY AS THE UPPER LEVEL RIDGE OF HIGH PRESSURE REMAINS FIRMLY ENTRENCHED ACROSS THE SRN PLAINS. ADDITIONAL ISOLD SHOWERS AND TSTMS MAY REDEVELOP ACROSS FAR NWRN ZONES LATE THIS AFTERNOON AND TONIGHT AROUND THE WRN AND NWRN PERIPHERY OF THE RIDGE. THE UPPER LEVEL RIDGE OF HIGH PRESSURE WILL SLIDE OFF TO THE EAST ON TUESDAY. THEN A WEAK COLD FRONT WILL SLIDE SEWD ACROSS THE REGION TUESDAY NIGHT.
NOT TOO MUCH CHANGE IN THE SYNOPTIC PATTERN ACROSS THE FL PENINSULA TODAY AS WEAKENING MID LEVEL TROUGH REMAINS OVERHEAD. WITH THE LOW LEVEL BOUNDARY LIFTING FURTHER NORTH. WEAKNESS IN SUBTROPICAL RIDGE VICINITY OF FLORIDA IS FORECAST TO MIGRATE ONLY SLOWLY WEST INTO THE GULF OF MEXICO. THIS WILL ALLOW DEEP LAYER RIDGE TO BUILD BACK INTO THE FLORIDA PENINSULA BY THE WEEKEND.
THE UPPER LEVEL RIDGE SHIFTS SLIGHTLY TO THE EAST-NORTHEAST TODAY. A SLIGHT DECREASE IN 1000-500 MB THICKNESS VALUES THE NEXT TWO DAYS WILL YIELD MAX TEMPS A DEG OR SO COOLER IN SOME AREAS THAN OVER THE WEEKEND.
AS A LEE TROUGH DEVELOPS ACROSS ERN MT SWD INTO WRN SD AND ERN WY. A STRONG UPPER LEVEL LOW PRESSURE SYSTEM WILL TRACK ACROSS THE NRN ROCKIES AND THEN ALONG THE US/CANADA BORDER. AHEAD OF A THE SYSTEM A STRONG THERMAL RIDGE/ELEVATED MIXED LAYER WILL DEVELOP. EXPECT TUESDAY TO BE WINDY AND MUCH COOLER WITH HIGHS IN THE UPPER 70S TO MID 80S.
ALTHOUGH THE SOUTHWEST FLOW ALOFT WILL REMAIN FAIRLY WEAK, THUNDERSTORMS ARE LIKELY TO DEVELOP LATE THIS AFTERNOON IN THE VICINITY OF THE LEE SIDE TROUGH IN EASTERN COLORADO AS LOWER/MID LEVEL LAPSE RATES STEEPEN. VERY MILD TEMPERATURES CAN BE EXPECTED TONIGHT AS A PREVAILING SOUTHERLY FLOW CONTINUES TO REINFORCE THE WARMER AIR MASS SETTLED ACROSS THE HIGH PLAINS OF WESTERN KANSAS. MEDIUM RANGE MODELS INDICATE AN UPPER LEVEL TROUGH TURNING EASTWARD OUT OF THE PACIFIC NORTHWEST INTO THE NORTHERN ROCKIES MONDAY NIGHT THEN PUSHING FURTHER EAST INTO THE NORTHERN PLAINS TUESDAY.
220 AM EDT MON JUL 27 2015 REMNANTS OF A COLD FRONT SPLATTER PATCHY PRECIP OVER THE FORECAST AREA TODAY.
205 AM EDT MON JUL 27 2015 A DRY ATMOSPHERE AND WEAK HIGH PRESSURE WILL ENSURE DRY CONDITIONS THROUGH THE OVERNIGHT. HIGH PRESSURE WILL RIDGE INTO THE FORECAST AREA FROM THE NORTHEAST THROUGH THE OVERNIGHT. UPPER HIGH WILL REMAIN CENTERED TO OUR WEST WITH NORTHERN STREAM UPPER TROUGH DEEPENING SOME ALONG THE US EAST COAST. WEAKENING UPPER LOW AND STALLED FRONT TO REMAIN TO OUR SOUTH. AS THE UPPER TROUGH DEEPENS SOME. UPPER HIGH WILL REMAIN CENTERED TO OUR WEST.
159 AM EDT MON JUL 27 2015 HIGH PRESSURE SLIDE OFFSHORE TONIGHT INTO EARLY MONDAY. THE HIGH REMAINS OFF THE COAST THROUGH MIDWEEK.
AS STRONG HIGH PRESSURE BUILDS IN ALOFT AND ONSHORE FLOW WEAKENS CONSIDERABLY.
CENTER OF DOMINANT UPPER RIDGE WILL MEANDER ABOUT THE SRN PLAINS INTO MIDWEEK BEFORE GRADUALLY MIGRATING INTO THE WRN STATES LATE IN THE WEEK. BETTER CHANCES OF ISO/SCT PRECIP PROBABLY OCCUR IN THE THUR-SAT TIME PERIOD AS RIDGE REPOSITIONS ITSELF TO THE WEST.
109 AM EDT MON JUL 27 2015 HIGH PRESSURE SLIDE OFFSHORE TONIGHT INTO EARLY MONDAY. THE HIGH REMAINS OFF THE COAST THROUGH MIDWEEK.
THE HIGH RESOLUTION REFLECTIVITY TRENDS SUGGEST THE FAR NORTHWEST AND FAR NORTH CENTRAL WOULD BE THE PRIMARY THREAT AREA FOR SHOWERS/THUNDERSTORMS THROUGH 18Z MONDAY. ALONG WITH THE WIND AND THE COOLER TEMPERATURES. GREATEST CHANCES WILL BE OVER THE NORTHWEST SHIFTING TOWARDS THE NORTH CENTRAL AS THE LOW WORKS EAST. RIDGE BUILDS OVER WESTERN CONUS MAINLY BRINGING DRY NORTHWEST FLOW THROUGH THE END OF THE WORK WEEK.
Water vapor satellite imagery shows the Southern Rockies/Southern Plains upper high/ridge axis is nudging/building northward with the corresponding plume of subtropical mid/high level moisture swirling more into NE and heading towards southern SD and IA vs northern KS/southern IA/northern MO. To offset that expect to see slightly warmer temperatures. Will hold off on extending headlines into Tuesday as it's a bit more complicated owing to a cold front approaching northwest MO in the afternoon and uncertainty as to how far east these "drier" dewpoints will spread east.
HEAT WILL CONTINUE TO BE THE DOMINANT THEME TO KICK OFF THE WORK WEEK AS AN UPPER RIDGE REMAINS CENTERED BETWEEN THE SOUTHERN PLAINS AND DEEP SOUTH. TUESDAY WILL LIKELY BE A SIMILAR DAY, THOUGH ISOLATED CONVECTION MAY BE POSSIBLE A BIT FARTHER WEST IN THE AREA, AS THE CORE OF THE UPPER RIDGE BEGINS TO RETROGRADE.
249 AM CDT MON JUL 27 2015 ANOTHER HOT DAY IS IN STORE FOR NORTH TEXAS AS AN UPPER LEVEL RIDGE REMAINS CENTERED OVER OKLAHOMA.
TEMPERATURES WILL ALSO TREND A LITTLE COOLER WITH INTRUSION OF WEAK COLD FRONT.
AN UPPER TROUGH EXTENDS FROM WESTERN CANADA SOUTH TO SOUTHERN CALIFORNIA EARLY THIS MORNING. A LOW CENTER WITHIN THIS TROUGH IS ROUGHLY OVER BENTON COUNTY IN SOUTHEAST WASHINGTON. THIS LOW CENTER WILL CONTINUE TO DRIFT EAST THIS MORNING TOWARDS IDAHO. MOISTURE AHEAD OF THE TROUGH AXIS LINGERS OVER WALLOWA COUNTY AND COULD PRODUCE SCATTERED SHOWERS THIS MORNING. OTHERWISE EXPECT MOISTURE WRAPPING AROUND THE LOW CENTER TO CAUSE ISOLATED TO SCATTERED SHOWERS OVER PORTIONS OF EXTREME NORTHEAST OREGON AND SOUTHEAST WASHINGTON INTO THIS EVENING. UPPER LEVEL HIGH PRESSURE WILL BEGIN TO BUILD INTO THE REGION LATE TONIGHT AND TUESDAY. HIGH TEMPS TUESDAY WILL RUN 5 TO 10 DEGREES WARMER THAN THIS AFTERNOON.
129 AM EDT MON JUL 27 2015 WEAKENING MID LEVEL TROUGH IS ALLOWING FOR CLOUDS AND CONVECTION TO DIMINISH THIS EVENING. /ISSUED 413 PM EDT SUN JUL 26 2015/ HEAVY RAIN THREAT WILL CONTINUE FOR COASTAL COLLIER, WITH TRAINING AND POSSIBLE REDEVELOPMENT OF SOME CONVECTION TONIGHT IN THE GULF, WITH LOW PRESSURE AND MIDLEVEL DISTURBANCE NEARBY. INTO THE MIDDLE OF THIS WEEK, HIGH PRESSURE SURFACE AXIS WILL LIFT NORTH SLOWLY THROUGH SOUTH FLORIDA, AND THE AREA OF LOW PRESSURE NOW JUST WEST OF TAMPA WILL WEAKEN AS IT DRIFTS NORTH INTO THE BIG BEND OF FLORIDA.
A MID LEVEL INVERTED TROF MOVG W AROUND THE BASE OF A HIGH PRESSURE SYSTEM CTRD ACROSS THE TX PAN HANDLE. THE INCREASED MOISTURE SHOULD KEEP MX TEMPS A COUPLE OF DEGREES COOLER TODAY. IF MX TEMPS AND DEWPOINTS BOTH HAPPEN TO BE A COUPLE OF DEGREES WARMER THAN ANTICIPATED. THIS IS DUE TO THE INVERTED TROF.
355 AM EDT MON JUL 27 2015 WARM CONDITIONS WILL CONTINUE TODAY WITH MAINLY DRY CONDITIONS DUE TO PERSISTENT HIGH PRESSURE. AN UPPER LEVEL RIDGE OF HIGH PRESSURE WILL BUILD ACROSS THE REGION TONIGHT INTO TUESDAY PROVIDING WARM AND HUMID CONDITIONS TUESDAY AFTERNOON.
OTHERWISE AN UPPER RIDGE OF HIGH PRESSURE OVER THE CENTRAL U.
THE SURFCE HIGH MOVES ONLY SLOWLY TO THE EAST TODAY AND TONIGHT AS UPPER RIDGE BUILDS ACROSS WISCONSIN. WARMER AND MORE HUMID WEATHER EXPECTED TUESDAY AHEAD OF A COLD FRONT THAT WILL NOT REACH OUR FORECAST AREA UNTIL AFTER SUNSET.
ON THE SRN EN OF A STRONG SUMMER TROUGH THAT IS OVER THE INTER- MTN REGION. BUT SHUNTED SOMEWHAT BY THE TROUGH TO OUR NW AND THE WEAKENING UPPER HIGH NOW OVER NRN TX AND OK. ROSE A COLD FRONT WL MOVE THROUGH THE CWA EARLY TUE MORNING ASSOCIATED WITH A TROUGH MOVING OVER THE NORTHERN TIER.
353 AM EDT MON JUL 27 2015 HIGH PRESSURE REMAINS OFFSHORE THROUGH MIDWEEK.
HIGH PRESSURE WILL SET UP NEAR THE FOUR CORNERS BY THE MIDDLE OF THE WEEK RESULTING IN A RETURN OF MONSOON MOISTURE AND AN INCREASING POTENTIAL FOR SHOWERS AND THUNDERSTORMS.
352 AM PDT MON JUL 27 2015 A TROUGH OF LOW PRESSURE MOVING INLAND ALONG THE WEST COAST WILL BRING SLIGHTLY COOLER HIGH TEMPERATURES TODAY. HIGH PRESSURE TO THE EAST WILL STRENGTHEN AND EXPAND WESTWARD INTO CALIFORNIA.
659 AM EDT MON JUL 27 2015 A FRONT WILL REMAIN STALLED WELL TO THE SOUTHEAST OF THE REGION THROUGH MID WEEK WITH WEAK HIGH PRESSURE OVER THE AREA.
TEMPERATURES TODAY SHOULD BE A LITTLE WARMER THAN YESTERDAY, MOSTLY DUE TO LESS PRECIPITATION COVERAGE AND AN ASSOCIATED REDUCTION IN CLOUD COVER. DEEP UPPER TROUGH ALONG THE WEST COAST HELPING TO PUSH THE UPPER RIDGE EASTWARD THE NEXT COUPLE DAYS.
A SEASONABLY STRONG LOW PRESSURE SYSTEM CURRENTLY OVER THE PACIFIC NORTHWEST WILL MOVE INTO MONTANA LATER TODAY. WITH A TROUGH AXIS EXTENDING INTO THE GREAT BASIN. GUSTY SOUTHWEST FLOW WILL DEVELOP OVER CENTRAL AND NORTHERN ARIZONA IN RESPONSE TO THIS TROUGH AND THE DRY LAYER BELOW ABOUT 550MB WILL PERSIST. BUT CHANGES WILL BE STARTING LATER IN THE DAY AS THE TROUGH MOVES EAST.
236 AM CDT MON JUL 27 2015 Sub tropical ridge will continue to be the dominate wx feature this week. An upper trough moving across from the NW will displace the center of the ridge to the east and then it will build back to the west as the trough passes. By late in the week the center of the ridge will shift to the 4 corners region. However as the center of upper ridge will no longer be on top of the area should see a slight decrease in temps the next couple of days as 850mb temps begin to fall. The upper pattern switch to NW flow aloft as ridge shifts west would be more favorable for bringing precip down into the Permian Basin.
UPPER LEVEL TROUGH OVER SE OREGON IS PROVIDING LIFT FOR SHOWER AND THUNDERSTORM DEVELOPMENT OVER FAR SE OREGON AND SW IDAHO EARLY THIS MORNING. SHOWERS AND THUNDERSTORMS WILL CONTINUE IN THE WEST-CENTRAL AND EASTERN BOISE MTNS THIS AFTERNOON AS THE UPPER LOW CENTER SWINGS THROUGH N-CENTRAL ID INTO SW MT.
VERIFICATION INDICATES SLIGHTLY COOLER TREND WITH FLOW OFF LAKE MICHIGAN AIDING IN SLIGHTLY MORE COMFORTABLE CONDITIONS.
A weak and elongated area of low pressure will remain across the Florida peninsula.

120 AM EDT MON JUL 27 2015 A WEAK COLD FRONT DRAPED ACROSS THE LOCAL AREA WILL CONTINUE TO DRIFT SLOWLY SOUTHEAST TONIGHT. HIGH PRESSURE WILL BUILD OVER THE AREA FROM THE NORTH MONDAY AND TUESDAY.
THE SURFACE MSAS INDICATED THAT THE THETA-E RIDGE WAS JUST EAST OF THE DRY LINE. THE RADAR WIND PROFILES SHOWED A NOSE OF THE LOW LEVEL JET BETWEEN THEDFORD AND RAPID CITY. THUS STRENGTHENING THE THETA-E RIDGE ACROSS THE AREA ALONG THE DRY LINE. WITH THE LOW LEVEL JET EXTENDING INTO THE NEBRASKA SANDHILLS. COLD FRONT SHOULD BE EAST OR NEARLY EAST OF THE AREA BY TUESDAY MORNING. MODELS CONTINUE TO INCREASE SPEED OF THE COLD FRONT AND NOW LOOKS LIKE BY TUESDAY MORNING THE CONVECTION ASSOCIATED WITH THE FRONT WILL ALSO BE EAST OF THE CWA. TO GO ON THE HIGHER SIDE OF MOS GUIDANCE. SEE NO REASON WITH THE LOW DEW PTS AND MOSTLY CLEAR SKIES IN PLACE. BOTH THE MET AND MAV GUIDANCE DROPS THE LOW TO 50.
HEDGED CLOSER TO THE LOWER NUMBERS IN THE NORTH WHERE CONVECTION IS MORE PROBABLE. TEMPERATURES WILL BE WARMER ON TUE WITH THE BUILDING RIDGE. PERIODIC RIPPLES AND CONVECTION OVER THE HIGH PLAINS WILL LIKELY LEAD TO SEVERAL ROUNDS OF STORMS. AS LEE TROUGHING STRENGTHENS ACROSS THE WESTERN HIGH PLAINS.
THIS WILL ALLOW FOR SLIGHTLY WARMER TEMPS BUT ALSO SLIGHTLY COOLER HEAT INDEX VALUES.
645 AM EDT MON JUL 27 2015 HIGH PRESSURE WILL HOLD TO THE NORTH TODAY WITH LOW PRESSURE OVER THE GULF OF MEXICO. UPPER LEVEL RIDGE CENTERED OVER THE SOUTHERN PLAINS WILL BUILD SLIGHTLY EAST BRINGING RISING HEIGHTS ACROSS GEORGIA AND SOUTH CAROLINA.
A WARM FRONT WAS LOCATED OVER NORTHERN MISSOURI AND NORTHWEST KANSAS. DEW POINT RANGED MID 50S IN CENTRAL WISCONSIN TO THE LOWER 70S ACROSS SOUTH CENTRAL AND SOUTHWEST MINNESOTA AND IOWA. THIS WAS DEVELOPING NORTH OF THE WARM FRONT AND ON THE NOSE OF MODERATE TO STRONG 850 MB MOISTURE TRANSPORT. THE MODELS ARE SHOWING THAT THE SURFACE WARM FRONT WILL REMAIN WELL SOUTH OF THE AREA TODAY. MODERATE TO STRONG 850 MB MOISTURE TRANSPORT IS LOCATED IN THE VICINITY OF THE COLD FRONT ON TUESDAY AND TUESDAY NIGHT.
THERE WILL BE BETTER UPPER LEVEL SUPPORT FROM A NORTHERN ROCKIES TROUGH AND A STRONGER LOW LEVEL JET THIS EVENING.
THE UPPER LOW WAS EVIDENT OVER THE PACIFIC NORTHWEST EARLY THIS MORNING. THE FRONT AND UPPER LOW WILL STILL BE WEST OF THE NORTHLAND TUESDAY MORNING SO AS THE MORNING CONVECTION MOVES EAST.
Although the upper level ridge will continue to dominate, enough heating combined with slightly cooler mid level temperatures should allow for the development of isolated showers and thunderstorms this afternoon, generally south of Interstate 20. The upper level ridge will weaken and shift to the north slightly, allowing a little better moisture and a little cooler temperatures to move into the area for mid week.
NEVADA WILL ENJOY MUCH COOLER TEMPERATURES ON MONDAY. COLD FRONT HAS ALREADY CLEARED HUMBOLDT COUNTY AS OF MIDNIGHT, AND WILL EXIT THE CWA BY THE MID- MORNING HOURS. AIR BEHIND THE COLD FRONT IS IMPRESSIVELY COOL FOR JULY, WITH 700 MB TEMPS TUMBLING TO 4-6C ACROSS NORTHERN NEVADA. GUSTS WILL EXCEED 30 MPH ON/NEAR THE HIGHER TERRAIN. SUBFREEZING TEMPERATURES ARE EXPECTED IN THE TYPICALLY COLD ELEVATED VALLEYS OF NORTHERN ELKO COUNTY, SUCH AS WILDHORSE AND CHARLESTON.
WEAK LOW PRESSURE CONTINUES TO MEANDER AROUND, MAINLY NORTH AND CENTRAL FLORIDA THROUGH THE WEEK. THE LOW, ALONG WITH PWATS GENERALLY BETWEEN 1. AT 500MB, A HIGH PRESSURE RIDGE SITS OVER TEXAS. THIS LEAVES THE REGION UNDER A BROAD TROUGH IN THE MID LEVELS AS WELL. BY THE END OF THE WEEK, A COLD FRONT DOES MOVE INTO THE SOUTHEAST UNITED STATES. THIS WILL MAINLY HELP TO KEEP THE LOW IN THE AREA, AS WELL AS GENERAL INSTABILITY OVER THE SUNSHINE STATE, WITH SOMEWHAT LESS INSTABILITY OVER SOUTH FLORIDA. 8 INCHES AND ABOVE, WITH THE GULF COAST AND THE INTERIOR OVER 2 INCHES, WHICH IS ON THE HIGH SIDE. THE FREEZING LEVEL WAS ALMOST AT 16K FT. WEAKENING MID LEVEL TROUGH IS ALLOWING FOR CLOUDS AND CONVECTION TO DIMINISH THIS EVENING.
647 AM EDT MON JUL 27 2015 FAVORABLE STRETCH OF AVIATION CONDITIONS THIS TAF PERIOD UNDER PERSISTENT HIGH PRESSURE. TODAY AND TONIGHT STEADY AMPLIFICATION OF THE SOUTHERN PLAINS UPPER RIDGE INTO THE GREAT LAKES OVER THE NEXT 24 HOURS WILL PROVIDE THE MAIN BACKDROP FOR CONTINUED ABOVE NORMAL WARMTH THROUGH THIS TIME. DEEP LAYER SUBSIDENCE AND RESULTANT GREATER STABILITY WITH HIGH PRESSURE LOCKED IN AT THE SURFACE WILL ENSURE PLENTY OF SUNSHINE TODAY.
MVFR CIGS OVER MFE AND HRL WILL RETURN TO VFR AFTER 14Z AS DAYTIME HEATING BURNS OFF THE LOW LEVEL CLOUD DECK.
621 AM EDT MON JUL 27 2015 HIGH PRESSURE WILL BUILD OVER THE AREA FROM THE NORTH TODAY AND TUESDAY.
405 AM EDT MON JUL 27 2015 CURRENTLY - A SURFACE THROUGH LOWER TROP RIDGE AXIS IS GRADUALLY SHIFTING NORTHWARD OUT OF CUBA. WHILE A TROUGH ACROSS CENTRAL ALSO STEPS NORTHWARD. WITH THE MAIN AXIS OF SHOWER ACTIVITY ALSO MIGRATING NORTHWARD WITH THE TROUGH. FORECAST - THE TROUGH WILL CONTINUE TO LIFT EVER SO SLOWLY NORTHWARD WHILE THE LOW LEVEL RIDGE MOVES ACROSS THE KEYS OVER THE NEXT COUPLE OF DAYS. THERE IS SOME INDICATION THAT THE RIDGE AXIS WILL FINALLY SHIFT FURTHER NORTHWARD ACROSS CENTRAL FLORIDA THIS WEEKEND. WHILE DAY TIME HEATING OVER SOUTH FLORIDA BREAKS DOWN THE RIDGE.
LATEST RAP DECREASES AND ENDS CONVECTION DURING THE MORNING WITH CHANCES INCREASING AGAIN BY LATE AFTERNOON AND EVENING NEAR THE SOUTH DAKOTA BORDER BACK TOWARD CENTRAL NEBRASKA AS COLD FRONT APPROACHES AND LOW LEVEL JET DEVELOPS.
318 AM EDT MON JUL 27 2015 A FRONT WILL REMAIN STALLED WELL TO THE SOUTHEAST OF THE REGION THROUGH MID WEEK WITH WEAK HIGH PRESSURE OVER THE AREA.
LOW TO MID LEVEL ANALYSES SHOW SHOW ELONGATED TROUGH OFF THE SE GA/NE FL COASTS SW TO THE NE GULF OF MEXICO. UPPER LEVEL RIDGE WAS STILL LOCATED OVER THE SRN CONUS WITH RIDGE TO EXTREME SRN GA. LOW TO MID LEVEL TROUGH AXIS WILL REMAIN SITUATED OFF THE NE FL/SE GA COASTS. SOMEWHAT DRIER AIR MOVES SW AS LOW TO MID LEVEL SHEAR/TROUGH AXIS MOVES SEWD.
637 AM EDT MON JUL 27 2015 HIGH PRESSURE REMAINS OFFSHORE THROUGH MIDWEEK.
338 AM EDT MON JUL 27 2015 HIGH PRESSURE WILL BRING SEASONABLE TEMPERATURES. THE HIGH WILL MOVE OFFSHORE MID WEEK. MOST OF THE CONVECTION BY THE GUIDANCE IS SHOWN OVER THE HIGHER TERRAIN TO THE WEST. THE EASTERN CAROLINAS WILL BE SITUATED BETWEEN THE ATLANTIC RIDGE AND STRONG RIDGING OUT WEST. THIS WILL ALLOW MID LEVEL TROUGHING TO DEVELOP AND ACTUALLY AMPLIFY THROUGH THE PERIOD.
THEN COOLER READINGS FOR THE REST OF THE WORK WEEK FOLLOWING THE PASSAGE OF A COLD FRONT TONIGHT. THERE IS SOME UNCERTAINTY AS TO WHERE THUNDERSTORMS WILL ACTUALLY DEVELOP BUT A PUNCH OF DRY AIR AHEAD OF AN UPPER LEVEL TROUGH OVER THE NORTHERN ROCKIES WILL LIKELY BE THE TRIGGER WHICH SETS OFF THUNDERSTORMS TODAY.
A COLD FRONT WILL BRING MUCH COOLER TEMPERATURES TO NORTHERN AND CENTRAL UTAH EARLY THIS WEEK. HIGH PRESSURE ALOFT WILL RETURN FOR THE LATTER HALF OF THE WEEK WITH MOISTURE POTENTIALLY RETURNING LATE IN THE WEEK THROUGH THE WEEKEND.
THE MODEST MID LEVEL LOW THAT HELPED FIRE THE LARGE COMPLEX THROUGH NORTHWEST MEXICO LAST NIGHT WILL COMBINE WITH HIGH PRESSURE TO OUR EAST TO STACK THE FLOW MORE SOUTHEASTERLY OVER THE NEXT 24 HOURS.
1229 AM CDT MON JUL 27 2015 STRONG UPPER LEVEL RIDGE WILL CONTINUE TO DOMINATE OVER TEXAS AND THE PATTERN OF OVERNIGHT/EARLY MORNING CIGS AND CLEAR AFTERNOON AND EVENING WILL CONTINUE IN AUSTIN AND SAN ANTONIO. THE BROAD UPPER RIDGE AXIS CENTERED OVER NW TX EXTENDS MAINLY ALONG A W-E AXIS ALONG THE RED RIVER INTO ARKANSAS. A SECONDARY RIDGE AXIS EXTENDS SOUTH OVER SOUTH TX AND IS PREVENTING DEEP POCKETS OF LOW LEVEL MOISTURE FROM DEVELOPING INTO SHOWERS.

HIGH PRESSURE WILL REMAIN OVER MUCH OF THE EASTERN U. HIGH PRESSURE WILL REMAIN IN CONTROL FOR WEDNESDAY AND WEDNESDAY NIGHT AS WELL WITH DRY CONDITIONS AND ABOVE NORMAL TEMPERATURES CONTINUING AS WELL.
Tranquil weather and above normal temperatures will continue tonight into tomorrow as an upper level low digs into the western United States with an upper level ridge over the eastern United States. At the surface, an area of low pressure across western Wyoming will intensify overnight and shift southward into northeastern Colorado by tomorrow morning. Meanwhile, a large dome of high pressure will be found across the Eastern United States.
I am expecting a repeat performance wrt the low clouds today. then high temps will be limited to at least the lower 60s if not lower. I think that similar areas as yesterday will see the most persistent clouds which means the ern Ozarks and sthrn IL have the best chances to see clouds and cooler high temps. Cntrl and NE MO are expected to stay cloud free today and should once again see highs in the low 70s.
/ISSUED / WEAK UPPER TROUGH WILL CROSS THE SOUTHERN APPALACHIANS TODAY. HIGH PRESSURE CENTERED OVER THE NORTHEAST WILL KEEP THE FORECAST AREA IN AN EASTERLY FLOW THROUGH WEDNESDAY. THE WEAK SURFACE BOUNDARY VICINITY OF CENTRAL GA SHOULD KEEP THAT AREA IN SOMEWHAT WARMER AIR.

WARM FRONT PUSHING NORTHWARD THROUGH THE CWA CURRENTLY AND IT SHOULD WARM NICELY ALONG AND SOUTH OF THE FRONT. A WESTERN CONUS LONG WAVE TROUGH WILL SLOWLY MOVE EAST THROUGH THE SHORT TERM PERIOD. EVOLVING INTO A BROAD LOW PRESSURE AREA EXTENDING FROM COLORADO THROUGH NORTHWEST MINNESOTA BY WEDNESDAY AFTERNOON. AND THE DEPTH OF THE LOW LEVEL MOISTURE IS AT OR LESS THAN 1KM IN NAM SOUNDINGS AT THIS POINT.
THE BACK EDGE OF THE LOW CLOUDS IS BEGINNING TO APPROACH I-35 FROM THE WEST AND EXPECT FURTHER EROSION OF THESE CLOUDS THROUGH THE REMAINDER OF THE MORNING AND ESPECIALLY THIS AFTERNOON. THE LOWEST SURFACE VISIBILITIES HAVE REMAINED IN MORE RURAL LOCATIONS WHILE LOW CEILINGS ARE MORE OF AN ISSUE IN THE URBAN AREAS.
LARGE UPPER TROF SPLITTING AND MOVING VERY SLOWLY THROUGH EASTERN IDAHO TODAY THROUGH WEDNESDAY.
1223 PM EST TUE NOV 3 2015 HIGH PRESSURE OVER PENNSYLVANIA WILL MOVE SLOWLY TO THE EAST COAST AND A WARM SOUTH TO SOUTHWEST FLOW WILL CONTINUE MUCH OF THE WEEK.
SAN ANGELO TX 341 PM CST TUE NOV 3 2015 (Tonight and Wednesday) Latest analysis and satellite data show an upper ridge across the southeastern US with a trough deepening over southern California/Arizona. Southwest flow aloft is increasing across west Texas as the ridge continues to move off to the east and the upper trough approaches. At the surface, a lee trough over far west Texas has resulted in increasing southeasterly low level flow this afternoon, with dewpoints on the increase. we may see a few showers and very light rain or drizzle develop along the interstate 10 corridor as warm air advection develops ahead of the upper trough. As clouds move in during the day tomorrow, we will see cooler temperatures, with highs in the 70s.
CLOUDS HAVE BEEN RATHER TOUGH TO BREAK AGAIN TODAY THANKS TO WEAK NORTHERLY FLOW AND HIGH PRESSURE AT THE SFC. WARMER TEMPERATURES. THANKS TO THE UPPER RIDGING IN PLACE OVER THE REGION. IT WILL NOT COME BARRELING INTO AND THROUGH THE ARKLAMISS BUT WILL HAVE TO GRADUALLY ERODE THE UPPER RIDGE.
