324 AM MDT THU JUN 9 2016 Upper ridging continues across the central CONUS with the main axis crossing the Dakotas today. Upper trough is developing across the wrn CONUS with flow aloft becoming more southwesterly. Weak high pressure will set up just east of the CWA on Friday bringing back the warmer air. eastern pac troughing will support sw flow into the region by late in the weekend. This will eventually support cooler conds and a little better chances for rain. Very warm conds can be expected Sat as the thermal ridge pushes over the region, with mid to upper 90s and even some 100s expected on the sd plains.
147 AM EDT THU JUN 9 2016 High pressure will maintain dry and cool weather today. Dry and cool today with broad high pressure at the surface.
The combination of a strong marine push and incoming upper trough will bring below normal inland temperatures at least through Friday. Afternoon winds will be strong from the west each afternoon with the upper trough over the region while marine clouds will likely persist along the coast.
125 AM EDT THU JUN 9 2016 Cool high pressure through Thursday.
Shower activity may develop again on Friday, but will likely be more isolated in nature than that of today, with winds shifting more to southeast with high pressure becoming more dominant again across the Gulf.
320 AM EDT THU JUN 9 2016 High pressure will settle across the region today and tonight, then move offshore on Friday. Given this and mid level heights slowly rising as the center of the mid level trough slowly shifts north and eastward of New England, expect another pleasant day for early June. Dry conditions will continue, with high temps generally in the lower to mid 80s with skies generally sunny/mostly sunny (outside of a few high thin cirrus traversing the skies of central NC originating from the WSW of the area). Given airmass modification with the lack of any advection, we should see low temps a bit warmer than this morning.
Some cirrus clouds are arcing over an upper high to the southwest and moving over SLO and SBA county.
315 AM EDT THU JUN 9 2016 High pressure to our west builds across the area through the end of the week.
Winds will then remain light and become variable late this week as the ridge retreats eastward leaving the area in a rather flat pressure field. A weak trough of low pressure is situated across the Florida Keys, with above normal atmospheric moisture (see 00Z KEY RAOB), meanwhile low level steering flow is southwesterly.
Still, observations in the lower 90s have been recorded across southern counties this afternoon.
420 AM MDT THU JUN 9 2016 A weak upper level trough that has been in place over northern Colorado all weak will be nudged eastward today as rising heights move into the state from the west.
415 AM EDT THU JUN 9 2016 High pressure will maintain dry and cool weather today. Dry and cool today with broad high pressure at the surface.
351 AM EDT THU JUN 9 2016 Low pressure in the Gulf of St Lawrence will bring showers to Northern Maine today and tonight.
These clouds are originating from an upper low over the NW Gulf of Mexico coast within the subtropical jet.
142 AM PDT THU JUN 9 2016 A trough of low pressure moving into the Pacific Northwest will continue to bring cooler air to the lower elevations today and Friday.
CWA remains between an upper level low over the northeast and an open upper level low over eastern TX. This second upper low leads to southwesterly flow across the southern portion of the CWA, resulting in high clouds streaming across the area. Despite the higher moisture at 500mb across the southern half of the CWA, the better deep layer moisture is confined to the eastern Big Bend area, mainly CTY.
230 AM PDT THU JUN 9 2016 An area of low pressure will approach the area today bringing slightly cooler temperatures across the region. Additional chances of showers and thunderstorms will occur over the weekend along with much cooler temperatures as an area of low pressure moves across the region.
The low level pattern is far more complex with a stationary weak front over northeast Montana extended back to the north side of the Snowy and Belt Mountains with substantial warming in areas south of this boundary. The northwestern US will see a couple of slow moving Pacific troughs separated by some zonal flow to start the work week.
A weak high pressure ridge will remain north of the region providing a light easterly flow while a stalled frontal boundary remains near the FL GA border. Afternoon temps will be a couple of degrees cooler due to more clouds but will still manage to reach the lower to mid 90s inland and upper 80s coast. Our forecast area will remain on the eastern side of a persistent strong upper ridge extending from central Gulf of Mexico to the upper Midwest Sat-Mon. A weak trough develops over Gulf Coast region into northern Gulf of Mexico. with upper ridge axis shifting east of our forecast area. along with perhaps slightly cooler afternoon high temps.
KAMA VAD wind profile continues to measure southerly winds of 30 to 40 knots through the lowest 3000 feet. Thunderstorm development expected this afternoon across western sections, as old outflow boundary aligns with surface trof, predisposing environment for dryline sharpening.
/Tonight/ Warm advection underway across Iowa on backside of retreating high pressure. With focus of storms to the north overnight, much of the rest of the forecast area will see little threat for rainfall and much warmer readings tonight as warm sector moves into the state.
High pressure has shifted east of the area. High pressure has shifted east of the area. High pressure will begin to slide off to the northeast of the state tonight which will allow a very meager return flow pattern to creep back into Arkansas.
237 AM CDT THU JUN 9 2016 A weak upper level trough axis currently over Colorado will migrate slowly eastward today, and should spark off thunderstorms across Western Kansas for this afternoon/evening.
647 AM EDT THU JUN 9 2016 Temperatures remain cool for today under a northwest flow before gradually moderating Friday as high pressure moves in.
A few showers and storms may try to make it into NW OK again late tonight as an upper low nears, but confidence is certainly not as high as it was last night so we will continue with only a small area of low chance PoPs across the extreme NW.
Clear and calm skies currently over the region should lead to patchy fog very briefly around sunrise once again as dewpoints have risen into the lower 70s for much of the area.
Another quiet day across Upper MI as low-level ridging drifts across the area. While some guidance is showing temps falling well into the 30s across the central and east, passing clouds should limit the lowest temps to the typically colder locations with sandy soil across the interior east half. Dry air over the eastern UP along with lingering low level ridging during the evening will allow temperatures to cool into the lower 40s over the east. Increasing pressure gradient and southerly winds over the west will keep temperatures milder in the lower 50s.
The next 24 hours should remain exceedingly quiet and fair as high pressure remains anchored over the central/srn Applachians by the broad upper ridge over the Plains and the upper trof off the east coast. the short term will feature rising heights aloft, as a large upper level ridge builds across the central CONUS Fri-Sat.
659 AM EDT THU JUN 9 2016 High pressure will settle across the region today and tonight, then move offshore on Friday. Given this and mid level heights slowly rising as the center of the mid level trough slowly shifts north and eastward of New England, expect another pleasant day for early June. Dry conditions will continue, with high temps generally in the lower to mid 80s with skies generally sunny/mostly sunny (outside of a few high thin cirrus traversing the skies of central NC originating from the WSW of the area). Given airmass modification with the lack of any advection, we should see low temps a bit warmer than this morning.
345 AM MDT THU JUN 9 2016 High pressure will be building back over the forecast area today as the exiting Pacific trough pushes out into the plains. After our cooler day yesterday, temperatures will be making a good 3 to 6 degrees jump with readings back into the 15 degree above normal thresholds.
406 AM EDT THU JUN 9 2016 Temperatures remain cool for today under a northwest flow before gradually moderating Friday as high pressure moves in.
Broad upper ridge covers the west central states, with an embedded wave pushing into the northern plains. Upper ridge axis will cross the northern plains Thursday, with 850 mb thermal ridge axis aligning over the CWA ahead of a weak low pressure system.
103 AM EDT THU JUN 9 2016 High pressure moving into the area this evening will provide mostly clear skies tonight.
As the upper level trough departs east away from the region, an upper level ridge moves east towards the region. At the surface, there is a high pressure system to our north that will begin to move east towards the Mid-Atlantic states, but low level flow will remain mainly northerly through the period for now. A considerable dewpoint gradient exists across the area with Albany showing values in the upper 50s and the Gulf Coast showing values in the lower 70s. With a weak upper level trough situated over the northwest Gulf of Mexico, there will be some weak, broad ascent over portions of our forecast area.
115 AM EDT THU JUN 9 2016 High pressure will remain over the region today and tonight before sliding offshore later Friday into Friday night.
352 AM EDT THU JUN 9 2016 High pressure remains today.
High pressure will shift eastward across the region over the coming days. By the weekend, a trough will move through southern California, eventually ushering in much drier air from the west. The best chances for precipitation and thunderstorms are forecast on Friday afternoon over the high country.
309 AM CDT THU JUN 9 2016 07z/2am surface analysis shows ridge of high pressure extending from the Great Lakes into the Ohio River Valley. Convection has developed in advance of the low across southern Minnesota into northern Iowa where temp/moisture advection is maximized along the nose of a 30-40kt 850mb jet streak. As low and associated warm front shift further E/NE, scattered convection will shift out of the KILX CWA this afternoon. Once winds switch around to the S/SW, a much warmer airmass will spill into the area.
Quiet conditions continue across the mid state as upper level ridging continues to build over the Great Plains, and eventually will move over the eastern U. As the upper ridge moves eastward, temperatures will begin to climb into the weekend. In addition to rising temperatures, the low level winds will become more southerly on Friday, and bring in additional moisture to the mid state.
This is due to the upper level low pressure still hanging around the lower Texas coast and the surface easterly winds/onshore flow. As the upper low hangs around the Texas Coast high pressure is forming across New Mexico and West Texas. Tonight through Thursday night the upper low will move northeast up the coastline and gradually weaken as well. Before the upper low lets go of its grip on the Rio Grande Valley's weather it will help produce another day with enhanced sea breeze isolated storms across mainly the coastal areas and over the Gulf of Mexico.
604 AM EDT THU JUN 9 2016 High pressure remains today.
The GFS supports a weak wave riding overtop the ridge Thursday night.
Deep layered ridge extending from the Bahamas to Cuba and a low to mid level trough across Central and South Florida will keep a moist SW flow across South Florida through Friday.
128 AM EDT THU JUN 9 2016 High pressure from the Mississippi Valley will move east across the area Thursday.
425 AM MDT THU JUN 9 2016 An upr level trof ovr the area wl be slowly moving eastward into KS today, with an upr level ridge building into the area from the west. High temps today wl be above average with readings in the 90s ovr most of the southeast plains and 80s in the high valleys. Overnight low temps are expected to be in the upr 50s to around 60 ovr the sern plains and in the 40s over the high valley locations.
320 AM CDT THU JUN 9 2016 High amplitude ridging continues across the Central CONUS with a weakness noted on the eastern periphery of the broad high pressure center over the desert southwest. The upper ridge will be in full force Friday by covering half the CONUS and extending into Saskatchewan Canada. The vort lobe will hang around into the weekend along with precip chances before being booted off to the east by an approaching trof from the west.
A strong cold front extended from KSWO to KGOK to KJWG to south of KGAG at 0530Z.
With nearly zonal flow aloft the cold front stalls out in Kansas.
Strong cold front was moving south through northeast Kansas this afternoon.
patchy freezing drizzle is expected early this morning as the DGZ is unsaturated. Sfc ridging building in for Friday but another area of f-gen arrives Friday night and this one could put down a stripe of light snow across the central or northern forecast area.
A closed low along the Oregon coast will support isolated snow showers over southeast Oregon zones through Thursday morning. With clearing skies temperatures have already fallen below freezing across the area, meaning any water on untreated surfaces is becoming ice, and will be that way for days to come. With temperatures below freezing for the next several days standing water id city streets and low-lying areas will freeze. The cold front has moved to the region's south with a few lingering showers over the mountains where a winter storm warning will be expiring by 5 PM MST.
This will result in cooler temperatures with highs mainly in the upper 60s for areas south of I-20. Along and either side of I-20, we may see temperatures warm into the lower 70s, without the low cloud coverage throughout the day. Farther north, a shallow, but potent arctic cold front is expected to creep south into our northern counties during the morning hours. Due to this cold front moving into the area, highs in northern Haskell and Throckmorton counties may not make it out of the 50s.
A low pressure system moving south along the west coast will bring one final round of precipitation to mainly southern and central Utah to end the week. High pressure aloft will settle over the region for the weekend. A trough is diving south along the California coast this evening, with Utah and southwest Wyoming in a moist westerly flow on the eastern fringes of this trough. Precipitation will likely linger into Thursday night and Friday, before the low finally exits the region over the weekend.
VFR conditions prevail currently across eastern Oklahoma and western Arkansas with a cold front poised to move into the Tulsa metro area.
/61/ (From previous discussion) Low-level ridging will continue to build in from the east for the weekend, which should result in a decrease in low-level moisture and a warm and dry forecast, as well as slightly cooler overnight lows.
High pressure remains stretched from the Atlantic across the northern gulf coast. In the plains low pressure is moving northeast toward the Great Lakes Region.
westerly surface winds will prevail until backdoor cold front passes. Cold front has entered eastern 2/3 of Oklahoma Panhandle, ahead of schedule. Backdoor cold front shift surface winds to east and southeast by late morning or early afternoon. After our record breaking warm temperatures today we will see much cooler temperatures on Thursday. The cooler temperatures will be the result of a slowly intruding cold front from the northeast. This cold front is rather shallow so it's going to struggle getting on top of the Caprock but it could filter down the river valleys. Thursday night we will see temperatures fall below freezing across the area while isentropic lift brings ample low level moisture into the southeastern Panhandles. This lift could be enough to spark off some light freezing rain for the southeast.
Upper air analysis last evening showed zonal flow over the southern part of the country as a strongly tilted trough moves southward along the west coast. At the surface, high pressure was centered to the east and winds were from the southeast.
A beautiful sub-tropical ridge remains active over the Gulf of Mexico and Western Atlantic early this morning and will even expand north into the Southeastern United States through the short term period. The area of high pressure will keep the air mass boundary separating typically cold winter conditions north of the forecast area today. An upper trough over South Central Canada will shift east toward New England through the next twenty four hours and this frontal boundary may edge a little farther southeast into the Southern Appalachian region generating a few showers later tonight. Maintained the wind advisory for the highest terrain along the North Carolina border through mid morning today.
1101 PM EST Wed Jan 11 2017 A cold front will slowly approach from the west tonight through Thursday and will cross the region Thursday night.
336 AM CST Thu Jan 12 2017 High pressure centered well off the Atlantic Coast extending southwest into the eastern Gulf of Mexico early this morning. Low pressure over Lake Huron has a cold front to the southwest into west Texas. upper ridging developing over the Florida Keys, with southwesterly flow over much of the southern 2/3 of the country. Between ridge building over Florida and the eastern Gulf, and upper low digging into Baja California, not going to be much change in the pattern for the local area through the weekend.
This will occur to the north and west of a strong upper ridge extending from the central Gulf of Mexico into the western Atlantic Ocean, and over all of the Florida peninsula. A strengthening upper trough will dive southward along the California coast as high pressure further strengthens to to its east. Upper level high pressure will further strengthen over the region in response to a deepening upstream trough Southern California. Low temperatures will generally range from the lower 50s along the Nature Coast, to the mid 50s to low 60s elsewhere.
Short Term (Tonight - Tomorrow): A sharp cold front is moving through the forecast area this afternoon with a sharp dichotomy of temperatures across the CWA. The southern CWA has risen into the lower 70s while the northwestern CWA is in the lower 30s. This front currently extending from MCI to IRK will continue to push south across the rest of the CWA this evening and with strong CAA in behind the front, temperatures will drop below freezing across the entire CWA by tomorrow morning. Models are suggesting that there is the potential for light freezing drizzle across the southeastern CWA after midnight which could lead to light glazing on roadways however most hi-res models are keeping this precipitation southeast of the area.
High pressure will be Northeast of the region this period.
423 AM EST Thu Jan 12 2017 A warm front pushes north tonight. A cold front crosses Thursday night, but stalls just south of the area Friday. In addition to the precipitation, winds will be quite gusty once again, particularly across the higher terrain counties. Cold front will sink southward Thursday night and Friday, and stall south of the area Friday night.
352 AM EST Thu Jan 12 2017 More rain is expected today ahead of a cold front. The next cold front will keep in the risk for showers throughout the day, with the best chance coming during the afternoon, as the boundary approaches. There is the potential for these stronger winds to mix down to the surface, however, the greatest threat for advisory level winds will remain over the higher elevations, as the region remains in the warm sector. High pressure will build over the eastern Great Lakes behind the front, keeping the area dry on Friday.
Overnight lows expected to be a few degrees warmer than this morning but not by much. Thursday forecast will be very similar to today although maybe a degree or two warmer with continued light, easterly winds. High pressure residing north of the waters will maintain east- southeast winds.
High pressure ridge is moving a bit faster now and all but the far east is in southerly return flow by 12z Fri.
Cold air slammed into the region this morning behind another arctic cold front. A large and broad mid level low/trough sprawling across Canada and the northern tier of the CONUS was responsible for the cold air plunge.
1239 AM EST Thu Jan 12 2017 A cold front will slowly approach from the west tonight through Thursday and will cross the region Thursday night.
Mid level ridge will continue to build over the region as an upstream trough digs along the California coast. A low level ridge axis will continue from the Atlantic across north Florida.
121 AM EST Thu Jan 12 2017 Upper high building to our south will provide fair and warm conditions through Friday.
By then winds will have increased a bit over that area so my south is much warmer for overnight lows. Winds will decrease throughout the day as another area of high pressure builds into the Northern Plains.
218 AM MST Thu Jan 12 2017 Currently across the Tri-State region there is a cold front continuing to push south through the area. Temperatures will drop into the low teens to low 20s over the region tonight and winds will shift slightly at less than 10 mph. The upper level flow shows an approaching low pressure system in the western CONUS. Thursday brings dry conditions as well, with increasing cloud cover during the day with the approaching trough in the western states.
As the subtropical ridge continues building into the southeast into Thursday, primary moisture axis is shunted north of the state. /Issued 241 PM EST Wed Jan 11 2017/ Frontal boundary just north of the state is beginning to move Northward as a warm front and pulling the deeper moisture northward with it. Surface ridging from the Atlantic is building in underneath this exiting frontal system keeping us in very warm southerly flow.
113 AM EST Thu Jan 12 2017 Upper high building to our south will provide fair and warm conditions through Friday.
A winter storm watch will be issued for portions of southeast KS on Friday for the accumulation of freezing rain.
1027 PM MST Wed Jan 11 2017 Imagery shows broad longwave trof across the CONUS with an upstream axis stretching from WA to the southwest over the EPAC. A mesoscale jet streak with warmer air aloft is also moving across the northern border area of WY/MT. SFC has a cold front through the region east of the Divide with comparatively very cold air entrenched. much warmer to the west ATTM.
301 AM CST Thu Jan 12 2017 Strong/Arctic cold front pushing south of Interstate 44 this morning. Freezing line still appears to hold near the Interstate 44 corridor tonight into Friday with light freezing rain likely along and to the north.
A deepening low pressure system will come onshore over southern California during the afternoon. Active/complex pattern still anticipated during the longer term with meteorological concerns still including but not limited to pops, snow amounts, mixed/freezing precipitation potential at times(especially over far southeastern sections), gusty winds at times and temperatures.
Upper trough amplifies into central CA during the day on Thursday. Fairly dry through the weekend as a broad upper ridge remains over the area.
Colder drier air has come in behind yesterday's cold front but southward-moving upper low in Oregon will still support isolated snow showers in sern Oregon and swrn Idaho today. Through Friday the Oregon upper low will move south along 120W reaching southern California late Friday.
