Aikyam-Lab/Synoptic-Bench huggingface dataset:
235 PM CST Thu Mar 2 2017 A weak cold front which lies from southwest to northeast from near Hereford to Lipscomb will slowly push through the rest of the Texas Panhandle tonight. A new lee-side trough will encourage gusty southwest winds to develop again on Friday.
152 PM CST Thu Mar 2 2017 Much of the snow has ended, as high pressure over northeastern ND slowly extends a ridge over eastern SD and western MN. The area of high pressure will slide to our east, extending from MN through northern MO overnight. Highs will likely range from the low 30s northeast, to the low 50s southwest.
920 AM MST Thu Mar 2 2017 Dry conditions and much warmer temperatures will settle into the area through the coming weekend with high level cirrus clouds passing through the sky on and off. Dry and warm conditions will return as high pressure returns over the West Coast by midweek. Upper ridge building across the intermountain west today will result in a warming trend with high temperatures in the mid to upper 70s across the lower deserts. High pressure aloft will build over the eastern Pacific and SW Conus with 500mb heights remaining in the 570-576dm range for the weekend.
Lake-induced troughing looks to start to set up as northwesterly flow becomes established later this evening. Steep lapse rates favored in upslope flow should amount to slightly higher amounts of snowfall in the ridges; but overall, accumulations should be light due to early March solar radiation and recent warmth of ground temperatures.
Surface analysis places a 1031 mb ridge of high pressure centered over Arkansas this afternoon.
Tomorrow is not expected to be much different -- just a touch warmer, an increase in high clouds during the afternoon, and slightly stronger winds. A cold front moving through the Panhandle this afternoon is expected to quickly lose its impetus early this evening, pulling up stationary across the northwestern and north central zones, then undergoing frontolysis later tonight.
While a slightly cooler airmass has been advecting across the region today.
High pressure is over the state at this time. Sunny skies will continue with highs in the lower to mid 60s. winds will switch back to the north as a new cold front drops south into the state.
A coastal trough developing along the coast south of Texas will build northward into the state tonight and Friday. Expect this run-up to persist at least through the high tide Friday morning.
Currently, an arctic high pressure center was over the Red River Valley in southern Manitoba and North Dakota. to between Mobridge/Aberdeen. a western ridge and a Hudson Bay low was keeping the northwest flow aloft over the Dakotas. Tonight the upper level western ridge begins building eastward, and the surface arctic high continues moving southeastward, arriving in the upper Mississippi Valley by daybreak Friday morning. This will create some overrunning of warmer air with west/southwest winds moving over the shallow western edge of the receding arctic air. Lifting along the warm frontal boundary and weak frontogenetic forcing with modest mid-level lapse rates should result in some light snow beginning in northwestern ND after midnight, then expanding eastward across the state on Friday. The upper level western ridge Friday continues to build east bringing mild Pacific air to our region for the weekend.
234 PM EST Thu Mar 2 2017 Winds increase out of the west behind a cold front today, ushering in colder air.
The passage of a dry cold front and an upper level trough will bring an increase in clouds to TRI late tonight/early tomorrow morning, but cigs will be forecast to remain VFR.
1147 AM MST Thu Mar 2 2017 Winds out near Arlington and Elk Mountain area have weakened below warning thresholds, so allowed the high wind warning to expire earlier at 11pm. The sfc pressure gradient and upper level winds will remain low enough today to keep the strong winds at bay, but it will still be breezy across southeast Wyoming with broad high pressure situated out to our west.
Temps were in the low to mid 40s over southeast IL from Shelbyville to Charleston/Mattoon and Paris southeast. Could be some light rain showers late this afternoon/early evening south of I- 72 before cooler air changes light pcpn to light snow showers. Clouds to quickly decrease from nw to se during tonight as 1038 mb Canadian high pressure settles into IL Fri morning. Nearby high pressure Friday morning will bring a fair amount of sunshine, but mid/high clouds to already increase during Friday afternoon ahead of next approaching northern stream clipper system.
1048 AM CST Thu Mar 2 2017 Wx map shows high pressure building in from TX/OK, keeping a tight pressure gradient along and south of I-10, including the coastal waters. /issued 424 AM CST Thu Mar 2 2017/ A chilly night underway as much cooler air is spreading into the area on gusty northerly winds. Temperatures are currently running anywhere from 10 to nearly 25 degrees cooler than this time yesterday, ranging from 48 at Jasper to 62 at Patterson. Aloft, flow is nearly zonal beneath a longwave trough crossing the eastern CONUS.
/issued 555 AM CST Thu Mar 2 2017/ For the ArkLaTex, VFR expected as high pressure continues to drive a dry N/NE wind into the area.
1123 AM CST Thu Mar 2 2017 Cool temperatures and clear skies are occurring this morning across the area, as high pressure builds south across the Central Plains. Moderate west winds will occur during the first half of the day today, ahead of a dry, secondary cold front approaching from the northwest. Behind the front, high pressure will move southeast through the lower Missouri Valley tonight, with north winds becoming light by daybreak Friday. As high pressure pushes east of the area on Friday, winds will become easterly and then southerly by the afternoon hours.
140 PM MST Thu Mar 2 2017 Dry conditions and much warmer temperatures will settle into the area through the coming weekend with high level cirrus clouds passing through the sky on and off. Dry and warm conditions will return as high pressure returns over the West Coast by midweek. Clear skies prevail across the forecast area as a broad ridge overspreads the intermountain West. Surface dewpoints have dropped as low as the upper teens across south-central Arizona and temperatures continue to warm, with highs in the mid to upper 70s expected in the lower deserts. High pressure aloft will build over the eastern Pacific and SW Conus with 500mb heights remaining in the 570-576dm range for the weekend.
1250 PM EST Thu Mar 2 2017 Brief periods of MVFR cigs may impact the terminal sites through 01Z tonight as a cold front moves south through the region.
High pressure will build into the area Friday offering dry weather and colder temperatures.
Surface analysis this morning places a 1032 mb ridge of high pressure centered over the Lower Mississippi Valley. High pressure is centered over central Oklahoma. The high will shift slowly east today and should be over southwest Arkansas tonight. A weak cold front will move into the region from the north tonight. Temperatures will be on the chilly side with lows Friday morning in the low to mid 30s. The cold front will move south of the region Friday morning leaving dry weather over the forecast area. The air behind the cold front will be a little cooler so temperatures will be a few degrees lower than today with highs in the upper 40s to mid 50s. High pressure will be over the Ohio Valley by Friday night.
121 PM EST Thu Mar 2 2017 High pressure will build into the area behind the cold front promoting dry and cooler weather through the weekend. It will be dry behind the cold front this afternoon. The models show dry high pressure continuing to build into the forecast area from the west tonight. Some of the guidance has temperatures around freezing but this may be too cold because of mixing associated with the high building into the area. Dry High pressure will be across the region Friday through Friday night. Minimum temperatures Friday night are expected to be at or below freezing across the northern and central Midlands, and in the mid 30s over the southern Midlands and CSRA.
258 PM CST Thu Mar 2 2017 Early afternoon objective surface analysis indicated ridge axis extending from eastern ND into western NEb, and this is expected to develop across the FA overnight.
122 PM EST Thu Mar 2 2017 The region will remain under cyclonic flow from departing low pressure today with gusty west-northwest winds and scattered snow showers or flurries.
SHORT TERM (Tonight through Friday Night): High pressure building in behind a cold front is delivering cool, dry air at the surface and, along with a somewhat flaccid 500 mb flow overhead, will produce cloudy, mild weather for deep South Texas and the Rio Grande Valley during the short term forecast period.
1058 AM MST Thu Mar 2 2017 17Z water vapor imagery and RAP analysis indicated broad troughing across central and eastern portions of the country with ridge over west coast. At the sfc, high pressure was settling over the area. A few mid clouds may develop along H7 thermal ridge do to persistent WAA, but shallow moisture profiles and stable conditions would keep precip threat essentially zero. dry conditions will prevail as H5 ridge shifts to the east and nears the CWA. With deep westerly flow think leaning on the warmer/drier solutions are in order and pushed deterministic forecast towards that envelope of solutions.
These showers should diminish after sunset as boundary layer mixing and support from the departing upper trough decrease. High temperatures will be near to just below normal, ranging from the 20s northeast to the lower 30s southwest.
Meanwhile at the surface, a frontal boundary separating arctic air to the northeast and milder Pacific air to the southwest extended from near Williston to Garrison to Mobridge. This weekend we'll see a warm up as an upper level ridge moves in briefly.
Tonight and Friday An upper trough and surface cold front will move across northern Wisconsin during the late afternoon and evening hours.
Friday afternoon through this weekend: Increasing northerly flow will advect a cooler airmass over South Florida during the day Friday. For South Florida, this translates into very persistent northeasterly flow and cooler weather.
1022 AM MST Thu Mar 2 2017 08z surface analysis had low over central SD with a weak frontal boundary from eastern MT through the low into eastern NE. High pressure pushes into the CWA the rest of the day bringing seasonal temperatures. Upper ridge will build over the Rockies and push east. Lee trough from central MT into WY will morph into a warm front, moving through the CWA Friday night. Temperatures will be noticeably warmer.
1219 PM EST Thu Mar 2 2017 A cold front will move well east of the forecast area this morning.
314 PM EST Thu Mar 2 2017 Even slightly colder Tomorrow as one more cold front tracks through Southeast Michigan Tonight, with 850 MB temps starting out between -18 C to -19 C Friday Morning.
Coldest temperatures will be across the high mountains and valleys west of I-25 and in the North Platte river valley east of I-25.
For tomorrow, we'll get on the backside of the high as it works east, so winds will become southerly and increase in the afternoon.
The frontal boundary separating the arctic air to the northeast and more mild Pacific air to the southwest remained from near Williston/Crosby to near Garrison/Bismarck to east of Mobridge SD. Meanwhile at the surface, a frontal boundary separating arctic air to the northeast and milder Pacific air to the southwest extended from near Williston to Garrison to Mobridge. This weekend we'll see a warm up as an upper level ridge moves in briefly.
653 AM EDT TUE APR 19 2016 AVIATION COOLER AIR HAS MOVED INTO SOUTHWEST MICHIGAN AN WILL REMAIN OVER THE AREA INTO THE WEEKEND.
SOME RAIN IN THE LOWER ELEVATIONS. THE MOUNTAINS ARE EXPECTED TO SEE CONVECTIVE SHOWERS BECOME MORE NUMEROUS THROUGH LATE AFTERNOON AND EVENING AS ANOTHER WEAK WAVE ROTATING AROUND THE MAIN UPPER LOW REACHES THE NORTHERN MOUNTAINS. THE LONG LIVED UPPER LOW MOVES FROM THE NORTHEAST CORNER OF COLORADO AT 00Z TUESDAY EVENING. AN UPPER RIDGE WILL THEN MOVE INTO COLORADO FROM THE WEST.
RIDGING/HIGH PRESSURE OVER THE REGION AT ALL LEVELS CONTINUES TO BRING QUIET CONDITIONS LATE TODAY. THIS IS CURRENTLY ENABLING A COLD FRONT TO SINK SOUTH ACROSS THE GREAT LAKES. WE SHOULD STILL HAVE SIZABLE RIDGE/VALLEY DIFFERENCES AT NIGHT AND LARGE DIURNAL RANGES. THE LARGE CLOSED LOW THAT HAS BEEN PERSISTENT OVER THE WESTERN US WILL FINALLY BE MAKING ITS EASTWARD PROGRESSION DURING THE MIDDLE OF THE WEEK. THIS LOW IS EXPECTED TO BECOME AN OPEN WAVE AND PHASE INTO A NORTHERN STREAM TROF OVER THE NORTHERN PLAINS.
634 AM EDT TUE APR 19 2016 A MAINLY DRY COLD FRONT IS CROSSING THE REGION EARLY THIS MORNING. HIGH PRESSURE WILL PROVIDE MOSTLY SUNNY SKIES THIS AFTERNOON AND ON WEDNESDAY AS TEMPERATURES COOL TO MORE SEASONAL LEVELS.
254 AM CDT TUE APR 19 2016 Large closed low slowly drifting into the High Plains remains the main weather story for the next few days, as this system will continue to push several more rounds of rain into the region. For today, a weak cold front is becoming quasi-stationary near the southern and eastern borders of our forecast area, and this feature will be the primary focus for any rainfall through most of the afternoon. This will keep the higher precipitation chances focused across the Clinton/Sedalia areas and then up the US-63 corridor.
148 AM EDT TUE APR 19 2016 COLD FRONT MOVING THROUGH TONIGHT.
200 AM PDT TUE APR 19 2016 High pressure will keep winds light and temperatures well above seasonal averages through midweek. High pressure will begin to break down today as a low pressure system off the California coast begins to move onshore. The low will weaken significantly as it moves through northern California tonight.
558 AM CDT TUE APR 19 2016 Water vapor imagery depicting a well defined conveyor belt of moisture flowing into the region as a result of deep layered south-southwesterly flow well ahead of the Rockies upper low. At that time a rather prominent short wave trof will begin spreading large scale ascent from western MO into central MO as it rotates northeastward in advance of the slowly migrating upper low. The precipitation threat should then diminish overnight as the upper trof becomes more postively tilted and migratory, and as deeper moisture is transported into the OH/TN Valleys in advance of the advancing surface cold front.
141 AM EDT TUE APR 19 2016 COLD FRONT MOVING THROUGH TONIGHT.
106 AM EDT TUE APR 19 2016 HIGH PRESSURE WILL PREVAIL OVER THE REGION EARLY THIS WEEK. A WEAK BACKDOOR COLD FRONT WILL MOVE INTO SOUTHEAST SOUTH CAROLINA EARLY WEDNESDAY BEFORE DISSIPATING.
SOME RAIN IN THE LOWER ELEVATIONS. THE MOUNTAINS ARE EXPECTED TO SEE CONVECTIVE SHOWERS BECOME MORE NUMEROUS THROUGH LATE AFTERNOON AND EVENING AS ANOTHER WEAK WAVE ROTATING AROUND THE MAIN UPPER LOW REACHES THE NORTHERN MOUNTAINS. DRIER AND WARMER WEATHER WILL MAKE A RETURN FOR THE LATTER HALF OF THE WEEK AS AN UPPER RIDGE TAKES A COUPLE DAYS TO DEVELOP OVER THE STATE.
Mostly clear skies will continue overnight with lows ranging through the low to mid 50s. However, this won't limit temps too much for Tues with highs still reaching the lower 80s in most locations.
643 AM EDT TUE APR 19 2016 COLD FRONT LOCATED FROM NORTHEAST PA TO CENTRAL OHIO WILL CONTINUE TO MOVE SOUTHWARD THROUGH THE DAY. HIGH PRESSURE WILL BUILD INTO THE REGION INT HE WAKE OF THE FRONT.

415 AM CDT TUE APR 19 2016 VIGOROUS CLOSED UPPER LOW OVER THE CENTRAL ROCKIES TODAY WILL MOVE EAST INTO THE CENTRAL PLAINS STATES TONIGHT AND WEDNESDAY.
CLOSED UPPER LEVEL LOW WAS LOCATED OVER THE CENTRAL AND NORTH ROCKIES. UPPER LEVEL RIDGE HAS WEAKENED OVER THE MISSISSIPPI AND OHIO RIVER VALLEYS WHILE A RIDGE HAS STRENGTHENED OVER THE PACIFIC COAST. IT APPEARS THAT THIS BLOCKING PATTERN MAY BE IN THE PROCESS OF BREAKING DOWN THE NEXT COUPLE OF DAYS. WATER VAPOR IMAGERY SHOWS WHAT LOOKS LIKE A COUPLE OF WEEK SHORT WAVE TROUGHS THAT COULD BE ON TRACK TO MOVE OVER THE AREA TODAY SUPPORT AT LEAST SOME BROAD LARGE SCALE ASCENT.
208 AM EDT TUE APR 19 2016 HIGH PRESSURE OVERNIGHT. THE LOWEST MIDLEVEL RELATIVE HUMIDITIES REMAIN TO OUR NORTH AND EAST. DRY WEATHER COMES TO AN END AS A LOW PRESSURE SYSTEM ENTERS THE WESTERN GREAT LAKES. THE FIRST CHANCE OF PRECIPITATION WILL COME ON WEDNESDAY AFTERNOON AS A WARM FRONT LIFTS THROUGH. SOMEWHAT UNCERTAIN ON HOW LONG IT WILL TAKE THE LOWER ATMOSPHERE TO MOISTEN UP.
311 AM EDT TUE APR 19 2016 THE OVERALL LARGE SCALE WEATHER PATTERN CURRENTLY FEATURES A SPRAWLING RIDGE OF HIGH PRESSURE THAT HAS SETTLED OVER THE SOUTHEASTERN US. AND A LARGE TROUGH OF LOW PRESSURE THAT IS CURRENTLY SPINNING ITS WAY SLOWLY EASTWARD INTO THE WEST CENTRAL PLAINS. THIS TROUGH WILL BE WHAT FINALLY BRINGS RAIN BACK TO EASTERN KENTUCKY FOR THE LATTER HALF OF THE WEEK. TODAYS HIGHS ARE AGAIN EXPECTED TO BE WELL ABOVE NORMAL AS A RIDGE OF HIGH PRESSURE REMAINS ENTRENCHED ACROSS THE SOUTHEASTERN CONUS. AS AN AREA OF LOW PRESSURE APPROACHES FROM THE WEST. ALONG WITH THE PASSAGE OF A VERY WEAK WARM FRONTAL TYPE OF A BOUNDARY. UNTIL THE COLD FRONT ASSOCIATED WITH THE AFOREMENTIONED UPPER LEVEL TROUGH MOVES INTO THE AREA LATER IN THE WEEK.
314 AM EDT TUE APR 19 2016 A WEAK COLD FRONT IS EXPECTED TO BRING SOME CLOUDS AND COOLER TEMPERATURES TODAY. DECOUPLING THE LOWER ATMOSPHERE RESULTING IN CALM WINDS AT THE SURFACE. EARLY MORNING TEMPERATURE READINGS AGAIN DEPEND ON LOCATION AND TOPOGRAPHY WITH URBAN HEAT ISLANDS AND HIGHER ELEVATIONS WARMER THAN COOL DRAINAGE AREAS IN THE VALLEYS. A WEAK FRONT WILL DROP IN FROM THE NORTH ERODING THE GRIP OF THE UPPER-LEVEL RIDGE THAT HAS BEEN IN PLACE. BUT GIVEN THE COPIOUS DRY AIR NEAR THE SURFACE AND THE HIGH PLACEMENT OF THE DEEPER MOISTURE ALONG THE FRONT. COOLER AIR BEHIND THE FRONT WILL BRING LOWS TONIGHT BACK DOWN CLOSER TO AVERAGE. TAX H500 RIDGE AXIS HANGS TOUGH OVER THE CWA THROUGH WEDNESDAY.
133 AM EDT TUE APR 19 2016 UPPER AIR PATTERN CONSISTS OF A CLOSED 500 MB LOW OVER NW CO THIS MORNING AND THERE IS A RIDGE OVER THE SERN U. THE CLOSED LOW WILL MOVE INTO NE CO BY 00Z WED. NAM SHOWS A NARROW RIBBON OF MOISTURE MOVING THROUGH THE AREA TODAY WITH THE COLD FRONT. TROUGHING APPROACHING FROM CENTRAL CANADA WILL PICK UP THE MID-LEVEL LOW ON THU. EXPECT INCREASING CHANCES OF SHOWERS WED NIGHT AS THE LOW STARTS TO SHIFT NE AND ENHANCED LIFT FROM THE TROUGH ARRIVES. TEMPS LOOK TO FALL DURING THE DAY THU AFTER A TRAILING COLD FRONT CROSSES THE CWA THU MORNING. THERMO PROFILES SUPPORT A POSSIBLE TRANSITION TO FREEZING DRIZZLE OVERNIGHT IF PRECIP HOLDS ON LONG ENOUGH. EXPECT HIGH PRESSURE TO BRINGS LIGHT WINDS THROUGH WEDNESDAY.
400 AM EDT TUE APR 19 2016 CLOUDS WILL INCREASE TODAY AND TEMPERATURES WILL BE COOLER BUT DRY CONDITIONS WILL CONTINUE UNTIL WEDNESDAY.
342 AM PDT TUE APR 19 2016 An area of high pressure will continue warm temperatures today. A series of upper level disturbances will bring cooler temperatures increasing chances for precipitation by the end of the week. Lots of high clouds spreading up from the southwest early this morning ahead of a closed low off the central California coast. High pressure and diminishing offshore flow will continue to dominate the weather pattern resulting in above normal temps today. The pattern will begin to change later today and Wednesday as the offshore low lifts out across the northwest corner of the state, nudged by a deeper upstream trough.
Sufficient instability is likely to develop into southern OK to allow this convective zone to realize the highest precip amounts. though the higher chances of any sustained severe weather threat will likely remain south of the forecast area. Convection exists western AR Wednesday morning with dry weather and warmer temps returning by the afternoon.
THE UPPER LEVEL LOW PRESSURE SYSTEM CENTERED ACROSS COLORADO WILL MOVE EAST INTO THE CENTRAL PLAINS STATES LATER TODAY. HIGH PRESSURE ALOFT WILL RETURN TO THE GREAT BASIN MIDWEEK.
UPSTREAM SYNOPTIC FORCING ASSOCIATED WITH UPPER LEVEL JET AND SHORT WAVE CLIMBING WEST SIDE OF RIDGE WL CONTINUE TO WEAKEN THIS MORNING AS IT PROGRESSES INTO CONFLUENT UPPER LEVEL FLOW. HIGH PRESSURE RIDGE WL REMAIN ANCHORED OVER NRN GTLAKES THRU TONIGHT. COOLER AIR ASSOCIATED WITH BACK DOOR COLD FRONT AND WIND SHIFT CONTINUES TO OVERSPREAD CWA EARLY THIS MORNING. DAYTIME TEMPERATURES TODAY WILL BE 20 TO 30 DEGREES COOLER THAN YESTERDAY DUE TO COOLER LOW LEVEL AIR.
609 AM EDT TUE APR 19 2016 A WEAK COLD FRONT IS EXPECTED TO BRING SOME CLOUDS AND COOLER TEMPERATURES TODAY. A WEAK FRONT WILL DROP IN FROM THE NORTH LOOSENING THE GRIP OF THE UPPER-LEVEL RIDGE THAT HAS BEEN IN PLACE. COOLER AIR BEHIND THE FRONT WILL BRING LOWS TONIGHT BACK DOWN CLOSER TO AVERAGE. TAX H500 RIDGE AXIS HANGS TOUGH OVER THE CWA THROUGH WEDNESDAY.
415 AM MDT TUE APR 19 2016 THE FORECAST AREA REMAINED UNDER THE INFLUENCE OF THE BROAD CLOSED LOW WHICH HAS DOGGED THE REGION OVER THE PAST SEVERAL DAYS. THE LOW CENTER WAS JUST SHIFTING EAST OF COLORADO/S CENTRAL DIVIDE MOUNTAINS EARLY THIS MORNING. THIS ISN/T THE END OF THE STORY FOR THE PERSISTENT LOW PRESSURE SYSTEM AS A 70 KT JET WORKING SOUTHWESTWARD ON THE WESTERN FLANK OF THE SYSTEM GUIDES ANOTHER VORT LOBE ACROSS NORTHEAST UTAH AND NORTHWEST COLORADO TODAY AND TONIGHT. PARTLY CLOUDY AND DRY CONDITIONS ARE IN STORE FOR SOUTHEAST UTAH AND THE LOWER ELEVATIONS OF SOUTHWEST COLORADO.
407 AM EDT TUE APR 19 2016 A WEAK COLD FRONT WILL CROSS THE SOUTHERN PORTIONS OF THE REGION THIS MORNING. HIGH PRESSURE WILL BUILD INTO THE REGION INT HE WAKE OF THE FRONT. THE HIGH WILL TRACK DRIFT SOUTHEASTWARD ACROSS NY STATE ON WEDNESDAY. A WARM FRONT WILL LIFT NORTHEASTWARD ACROSS THE AREA WEDNESDAY NIGHT.
AXIS OF MID/UPPER LEVEL RIDGE HAS FINALLY PUSHED EAST OF THE CWA THIS MORNING. BUT DRY AIR REMAINS IN THE LOWER LEVELS AT LEAST OVER THE EASTERN HALF OF THE CWA. THIS TIGHT DEWPOINT GRADIENT HAS INDUCED A PSEUDO DEWPOINT BOUNDARY DRAPED ACROSS EASTERN LA SEPARATING UPPER 40S DEWPOINTS IN THE EAST WITH THE LOWER 60S DEWPOINTS IN THE FAR WEST.
140 AM EDT TUE APR 19 2016 AVIATION A COLD FRONT WILL MOVE THROUGH TONIGHT WITH ONLY A SLIGHT CHANCE OF SHOWERS. FAIR AND COOLER WEATHER WILL FOLLOW FOR TUESDAY.

505 AM EDT TUE APR 19 2016 A COLD FRONT WILL MOVE THROUGH EARLY THIS MORNING.
CURRENT SITUATION AND ANALYSIS -- A LARGE-SCALE ANTICYCLONE DOMINATES THE LOCAL WEATHER PATTERN BOTH AT THE SURFACE AND ALOFT.
320 AM CDT TUE APR 19 2016 PESKY UPPER LOW CURRENTLY CENTERED OVER NE COLORADO WILL MAKE SLOW PROGRESS ACROSS NEB OVER THE NEXT COUPLE OF DAYS. WEAK MOISTURE TRANSPORT TO THE SOUTH OF THIS UPPER LOW MAY LEAD TO A SCATTERED SHOWER CHANCE ACROSS SE KS FOR THE MORNING HOURS. EXPECT A RATHER VIGOROUS IMPULSE TO ROUND THE SOUTHERN SIDE OF THE UPPER LOW AND MOVE ACROSS MOST OF THE FORECAST AREA LATE THIS AFTERNOON INTO TONIGHT. AS UPPER LEVEL LOW MAKES SLOW PROGRESS ACROSS NEB. WITH WEAKLY CAPPED ENVIRONMENT SOUTH OF THE LOW FOR MOST CENTRAL KS. BUT MOST LOCATIONS WILL SEE SEASONAL TEMPS AND LOTS OF SUNSHINE RETURN FOR THE END OF THE WEEK AS UPPER RIDGING FOR THU THROUGH SAT.
For Tuesday, the upper low and associated vort lobe moves east across the Central Plains with showers and isolated thunderstorms spreading west to east. For Tuesday night, the upper low and vort lobe will be moving east of the area with any lingering light showers ending west to east with the last area up around I-70 closer to the upper low. Highs will be warmer and in the mid to upper 60s and light winds.
