911 PM CST Tue Feb 14 2017 A weak cold front located over central Wisconsin this evening will shift south across our earea tomorrow morning bringing in a brief spell of colder weather for the Midwest Wednesday and Wednesday night before temperatures soar well above normal again for the end of the week. Latest satellite data indicates the band of lower clouds that was associated with the front have gradually dissipated as they shifted into the lower Great Lakes this evening. winds will become more northwesterly as high pressure builds into the Mississippi River Valley. split between cooler air moving in with the northwesterly flow and more sunshine providing ample daytime heating.
Preferred places for these isolated gusts up to 75 mph include Deep Creek and Two Medicine Bridge in Glacier County. High pressure will bring mainly VFR conditions with a few mid to high level clouds through much of the period.
324 PM EDT MON AUG 22 2016 High pressure will build in from the west tonight and will shift offshore south of New England on Tuesday.
The highest PoPs Tuesday will be over the western half of the CWA, ranging from 40% along/west of the Mississippi River to 20% farther east toward the Tennessee River Valley. Temperatures tomorrow will be near or just a few degrees warmer than today's highs, with max temps in the mid 80s to near 90 degrees. The Bermuda High will build over the southeast CONUS through the work-week with a large scale trough over the southwest. As we move into the weekend, the southwest trough will lift out, with the subtropical ridge elongating across the southern states. With mid-level heights approaching 595 dam, we'll see warmer temperatures across the Mid-South. In general, we're looking for temperatures climbing into the lower 90s.
227 PM CDT MON AUG 22 2016 Today has a break from the heat and humidity with temps at 2 pm in the lower 80s with low 60 dewpoints. A cdfnt stretches across srn MS/AL/GA with a large upper high pressure system covering portions of the sern US.
1212 PM CDT MON AUG 22 2016 A very low amplitude short wave trough noted on water vapor imagery moving northeastward across northern Chihuahua into Far West Texas should spawn isolated to scattered TS this afternoon and early evening.
However the slow moving trough will continue to allow some nocturnal convection through the late night hours.
1243 PM CDT MON AUG 22 2016 Ridge axis extends across northern Illinois southwest through the STL Metro area and into far northwest Arkansas. The ridge will continue moving east today which will bring the wind around to the south-southeast by mid to late morning. The southerly flow and high August sun angle will allow a solid warm up; however the cool start to the morning will likely only allow highs in the low and mid 80s even with a 30 degree warm up.
This activity developed in response to an upper level disturbance interacting with a warm front near Interstate 20 that is slowly moving northward. A mid-level ridge over the northern Gulf of Mexico will build and move the Lower Mississippi River Valley through the mid week time frame.
A strong dry cold front is moving through the region today. Winds will begin to diminish by mid evening as pressure gradients relax behind the exiting cold front.
An upper trough will slide over the Pacific Northwest bringing seasonal temperatures across northern California through the work week. Temperatures will decrease across the interior as 500mb heights fall with the upper trough moving over the Pacific Northwest. As the trough moves inland, 850 mb temperatures will warm as ridging builds in behind.
150 PM EDT MON AUG 22 2016 Drier and cooler airmass remains in place through the middle part of this week. Next cold front approaches by the end of the week. Ridge continues to build in from the west. Benign weather will continue through the short term as upper ridging transitions across the northeast. Temperatures will be slightly warmer on Tuesday after another relatively cool night climbing back into the lower 80s on Tuesday.
345 PM CDT Mon Aug 22 2016 SE Texas was on the western edge of a 500 mb ridge that was centered near northern FL today.
(Issued 1016 AM CDT MON AUG 22 2016) It was a refreshing morning with the cooler and drier air in place that filtered in behind the cold front. Otherwise, with the vast cloud cover associated with the upper level disturbance along with the cooler air in place, temps will be in the mid/upper 80s today.
Convection will diminish by midnight with temperatures falling into the low-mid 70s over much of the area overnight. Broad area of high pressure over the eastern U. Highs looks to still reach the low-mid 90s Tuesday.
305 PM EDT Mon Aug 22 2016 High pressure will provide cooler and drier conditions through the first half of the week. High pressure creeping eastward will mean clear skies and calm winds overnight, which will allow for the coolest night in at least two weeks, with all locations dropping into the 50s and isolated areas dipping into the 40s. High temperatures will return back into the low to mid 80s for most.
134 PM EDT MON AUG 22 2016 High pressure will bring beautiful late summer weather today and Tuesday with low humidity.
239 PM EDT Mon Aug 22 2016 High pressure will build eastward from the Ohio Valley today.
1201 PM CDT MON AUG 22 2016 Big picture across the Nation this morning shows a rather flat pattern in place at the moment with a modest ridge traversing the middle of the continent. Of interest to the forecast for later this week is the potent trough moving east across British Columbia early this morning. As this trough moves east through the Canadian Plains it will induce a bit of stormy activity as moisture returns from the Gulf start making their way back into Kansas and Missouri ahead of a frontal boundary that will develop across the Northern High Plains later today.
113 PM EDT MON AUG 22 2016 High pressure builds in from the northwest today ushering in a drier and more seasonable airmass to the Mid-Atlantic region. High pressure remains over the area through the middle of the week, before sliding offshore later in the week. High pressure will continue to build in from the northwest today.
In the wake of the upper trough moving off the Mid-Atlantic coast this morning, quasi-zonal flow aloft will develop across the area as the flat subtropical ridging extends across the GOM and Deep South. Subtropical ridging to our south begins to extend/amplify north the area on Tuesday. Lows a few degrees warmer than tonight, generally in the lower to mid 60s. High pressure and relatively dry airmass will continue to provide fair weather for the mid-to-latter portion of the work week.
WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO At 1 pm PDT, water vapor satellite imagery displayed an upper- level low near Point Conception and an upper-level ridge near central Baja. The ridge to our south will transition to our southwest tomorrow while an upper-level trough develops along northern CA up to the PAC NW.
132 PM EDT MON AUG 22 2016 High pressure will dominate through most of the week. A weak cold front will approach late in the week. High pressure over the Ohio river valley will slowly build east today. High pressure builds overhead tonight into Tuesday. Northern extent of southern upper ridging gradually builds into the region through mid week, flattening a bit late week into weekend. At the surface, sprawling high pressure builds in from the west through mid week, and then gradually centers itself south and east late week.
335 PM CDT MON AUG 22 2016 Scattered convection ongoing across NE TX is near the sfc warm front and this feature will lift northward tonight through Tues increasing precip chances areawide. The weak cold front slated to push into NE OK Wed night has continued to show less southward progression w/ subsequent model solutions and it is likely this boundary makes only a meager push beyond the OK/KS border.
601 PM EDT Mon Aug 22 2016 High pressure will provide dry weather through mid week before shower chances return with a late week cold front. High pressure should maintain dry weather and mostly clear skies through Tuesday as it moves east across the region. After cool morning lows, highs Tuesday should return to just above seasonal levels on the western side of the high.
519 PM EDT MON AUG 22 2016 A slightly cooler and drier air mass will filter into the area through mid week before the upper ridge builds back over the southeastern states. Large high pressure centered over the Ohio Valley will move east overnight. A dry and cool air mass is associated with the area of high pressure. Weak isentropic lift and weak short wave trough moving through the area suggests a few showers may develop.
156 PM EDT MON AUG 22 2016 A slightly cooler and drier air mass will build over the area through mid week before the upper ridge builds back over the southeastern states. A cold front pushed south through the forecast area this morning bringing northeasterly surface winds and a slightly cooler and drier airmass. Weak isentropic lift and weak short wave trough moving through the area suggests a few showers may develop.
109 PM EDT MON AUG 22 2016 VFR conditions should prevail through the taf period as high pressure slowly drifts across the Great Lakes.
330 PM EDT MON AUG 22 2016 High pressure will pass over our region on Tuesday before moving off the coast and drifting out to sea.
145 PM EDT Mon Aug 22 2016 High pressure will provide cooler and drier conditions through the first half of the week. High pressure creeping eastward will mean clear skies and calm winds overnight, which will allow for the coolest night in at least two weeks, with all locations dropping into the 50s and isolated areas dipping into the 40s. High temperatures will return back into the low to mid 80s for most.
137 PM CDT MON AUG 22 2016 Southwest flow aloft will prevail over southeast New Mexico and west Texas through the upcoming week, as the region remains sandwiched between an upper ridge over the southeastern ConUS and a persistent ua trough over the western ConUS. Will keep PoPs going most areas, and most periods, through the week under this regime as models also bring an assortment of perturbations/MCVs either north around the western fringe of the ua ridge, or northeastward ahead of, or associated with, the ua trough to the west.
1222 PM CDT MON AUG 22 2016 244 AM CDT Today through tonight: Early this morning skies remain mostly clear, as high pressure centered over Missouri begins to push east. Temperatures will continue to radiate prior to daybreak into the lower 50s and could see a few sites in the west/northwest forecast area fall into the upper 40s. But with the southerly flow persistent through the night, lows tonight will be several degrees warmer in the upper 50s to around 60.
204 pm cdt Mon Aug 22 2016 High pressure currently centered over the Ohio River Valley. High pressure will remain in control across the area through Tuesday. For Tuesday night, will be watching a rather vigorous mid-level low/trough push into southern Canada/Northern Plains. Southwest flow in the middle levels pulls a trough northeastward toward the region along with a push of 850mb moisture transport.
Drier conditions are expected Tuesday with shower chances generally confined to the higher terrain. Weak upper level low pushing through the area continues to generate shower and thunderstorm activity this afternoon. Convection so far has materialized across the Sierra and Mohave county and more recently isolated convection has increased across Lincoln/northern Nye county and the higher terrain of Clark County. As the low pushes east tonight, greatest chances for storms will transition eastward to become focused across Mohave county and eastern Lincoln county. Drier air will move in Tuesday but scattered storms are still a good bet across the higher terrain of southern Nevada and northwest Arizona thanks to lingering moisture and instability.
Despite upper ridging building into the area, mid level warm nose does not appear strong enough to completely preclude convection, so am still expecting isolated to scattered showers and thunderstorms each day through the period.
124 PM EDT MON AUG 22 2016 High pressure and a drier airmass will be in place across the region through Tuesday.
High pressure is in control across Middle TN today.
Upper low moving into southern Alberta this afternoon with very hot and dry conditions across eastern Montana. As the upper trof slides east overnight, a few showers could be triggered by the 700mb front. Colder air will spread east with the trof for temperatures 15 to 20 degrees cooler for Tuesday.
355 PM EDT MON AUG 22 2016 High pressure will dominate through most of the week.
We will see a gradual increase in heights aloft through the period as short wave ridging builds into the Ohio Valley and the all too familiar Bermuda High once again begins to exert its influence across the southeastern CONUS. Much drier air has mixed into the boundary layer this afternoon with dew points at a few locations dipping into the low 50s.
1154 AM MDT MON AUG 22 2016 Water vapor loop showed an upper low over central British Columbia with a trough into the Pacific Northwest. A weaker upper low was situated over western Arizona. A broad upper ridge dominated the Rockies and high plains. There is good agreement from the short range models progging the upper ridge axis to progress east across the Great Plains and Midwest through Tuesday. The British Columbia upper low will also track east across southern Alberta and Saskatchewan. Temperatures will be at least 10 degrees cooler with highs in the 70s and 80s.
135 PM EDT MON AUG 22 2016 Dry high pressure will build eastward into the Mid-Atlantic through mid-week. In the wake of the upper trough moving off the Mid-Atlantic coast this morning, quasi-zonal flow aloft will develop across the area as the flat subtropical ridge extends across the GOM and Deep South. Expect continued clear skies with high temperatures similar to today, and lows Tue night a few degrees warmer than tonight. -Vincent High pressure and relatively dry airmass will continue to provide fair weather for the mid-to-latter portion of the work week.
Clear skies and light winds will then prevail through the night under the influence of dry air and high pressure. The high will slide east on Tuesday, allowing for the development of light sw winds.
634 PM EDT MON AUG 22 2016 Cool high pressure builds into the area from the west tonight and Tuesday.
319 PM CDT MON AUG 22 2016 High pressure over both the Upper Mississippi and Ohio Valleys brought nice weather to E Iowa/NW Illinois/NE Missouri today. Lows are forecast to be warmer than last night. Tuesday night: A strong upper level trough will be tracking across the northern Rockies and upper Midwest.
138 PM EDT MON AUG 22 2016 Cooler and less humid conditions will dominate through Tuesday with highs in the upper 70s to lower 80s.
114 PM EDT Mon Aug 22 2016 High pressure will be in control through much of this week with dry and generally seasonable weather.
626 PM EDT MON AUG 22 2016 SYNOPSIS A cold front will move east into the Maritimes this tonight.
A trough is continuing to move eastward off the Eastern Sea Board, with an area of high pressure building in its wake. The trough off the east coast will head eastward while the area of high pressure builds over the southeastern United States through late Tuesday. As the ridge strengthens, winds will back and gradually increase, peaking Tuesday night.
Weak closed low and associated vorticity maxima will arrive on the KS/CO border by 7 pm. High temperatures will increase to the lower to middle 90s by Tuesday given the surface lee troughing and south winds.
High pressure centered over the region this afternoon will shift to the east overnight into Tuesday. However, ridging aloft and the high pressure should continue to exert enough influence that southern IN and central KY will remain dry through Tuesday night. Southerly return flow will set up tomorrow with highs expected to be a few degrees warmer than today.
An upper level low will continue to drift east through southern Alberta today. Onshore flow will result in cooler high temps areawide, with highs mainly low to mid 80s at the lower elevations and upper 60s to mid 70s in the mountains.
334 PM EDT MON AUG 22 2016 SYNOPSIS A cold front will move east into the Maritimes this tonight.
mid level high pressure to build over the Western Gulf and Eastern Texas increasing the subsidence across the region. As the 500 mb ridging from the Gulf of Mexico builds west over the Texas coastline over the next 24 hours expect the drier and more stable airmass to maintain VFR conditions for most of the upcoming TAF period. The 500 mb ridging in place over the Gulf of Mex should build west today and Tuesday which will dry out and stabilize the atms over the region reducing the conv chcs. As the 500 mb ridging builds over the region temps should warm up a bit through Tuesday as the 1000-500 mb thicknesses increase and the diurnal heating builds.
314 PM CDT MON AUG 22 2016 The high pressure ridge axis is slipping further to the east and the surface winds will become increasingly more southerly as the evening progresses and through tomorrow. particularly in the east, closer to the ridge axis and the lighter winds. The overall weather pattern shows an upper low in eastern British Columbia progressing eastward, with a strong upper ridge in the east- southeastern U.
319 PM EDT MON AUG 22 2016 High pressure and a drier airmass will be in place across the region through Tuesday.
314 PM CDT MON AUG 22 2016 Quiet night, as high pressure moves slowly east.
300 PM EDT MON AUG 22 2016 Drier and cooler airmass remains in place through the middle part of this week. Next cold front approaches by the end of the week. Ridge continues to build in from the west. Benign weather will continue through the short term as upper ridging transitions across the northeast.
1220 PM CDT MON AUG 22 2016 Stalled frontal boundary to the south of the forecast area is forecast to move northward as a warm front overnight.
High Great summer weather will continue through Tuesday under the western periphery of high pressure. There will likely be a few more clouds tomorrow than today as the high pushes farther east, along with somewhat breezier winds. The clouds shouldn't disrupt heating much, so looks like a mild day with seasonable highs in the low 80s.
1254 PM CDT MON AUG 22 2016 High pressure centered over the region will keep winds generally light and somewhat variable. High pressure area centered over the CWA will slowly move east through tonight. Temps tonight will decrease again with the coolest temps, upper 50s, being in eastern IL, closer to the high pressure area and lighter winds. Slight warmer temps, around 60 will be seen in western IL.
Activity may persist overnight as a weak upper low crosses the area. This upper low will drift through northern Arizona on Tuesday, with even colder air aloft.
143 PM EDT MON AUG 22 2016 A slightly cooler and drier air mass will build over the area through mid week before the upper ridge builds back over the southeastern states. A cold front pushed south through the forecast area this morning bringing northeasterly surface winds and a slightly cooler and drier airmass. Weak isentropic lift and weak short wave trough moving through the area suggests a few showers may develop.
351 PM EDT MON AUG 22 2016 As high pressure retreats, one last cool night before warmer and more humid air moves into the region.
306 PM CDT MON AUG 22 2016 An upper level jet streak is rounding the base of a short wave trough, moving across southern Arizona and southern New Mexico. Rich deep layer moisture is being drawn northward from South Texas and northern Mexico as south to southwest mid/upper level flow increases on the interface between the upper trough and the subtropical high centered over the Gulf Coast states. Tonight's lows should be warmer than the last several nights, mainly as a response to increased surface dew point temperatures.
948 AM EDT Tue Nov 1 2016 High pressure over Quebec will drift south to the Carolina coast through Wednesday.
KABI should be near the northern edge of the low cloud field, where MVFR ceilings will be possible by or after 12Z. Winds will be mainly from the south today and tonight, with the higher speeds and gusts at KABI. An upper trough entering the west coast will dive southeast later today and tonight, with a closed low developing over northwestern Arizona by early Tuesday morning.
Points farther inland and north fell into the low-mid 60s. High pressure extends through a deep layer over area. The low level ridge axis lies to the north with continuation of onshore flow and generally dry conditions today.
Warm air continues to stream across the region this morning as an upper level trough gradually shifts east into the Upper Mississippi Valley.
Winds should remain fairly light AOB 10 kts, starting from the north and becoming southerly AFT 01/18Z as a weak cold front retreats northward. For today, a weak cold front will slowly settle southward into nrn zones this morning before lifting nwd again later this afternoon. This boundary, combined with periods of high level clouds, will result in slightly cooler max temperatures this afternoon. On Wednesday and Wednesday night, an upper level low pressure system will dig into srn Arizona and become quasi-stationary. The combination of a swd moving cold front and adequate moisture return supports slgt chc to chc pops across much of the fcst area Wednesday and Wednesday night.
958 AM EDT Tue Nov 1 2016 A warm front pushes through the area this morning, with warm afternoons today and Wednesday.
530 AM MDT Tue Nov 1 2016 Current surface map places high pressure across western South Dakota. Northern wave of splitting upper trof slides across the area tonight. Temperatures marginally cold enough for rain/snow mix in the higher elevations of the Black Hills overnight.
1010 AM EDT Tue Nov 1 2016 High pressure will extend across the Middle Atlantic and Carolinas through Wednesday.
/issued 500 AM CDT Tue Nov 1 2016/ WV imagery shows the upper-lvl ridge continuing to shift eastward in response to an incoming trough, and is now centered over the Gulf of Mexico.
1019 AM EDT Tue Nov 1 2016 Aviation section updated Unseasonably warm conditions will continue through mid week, then a cold front and upper trough will bring cooler but seasonable readings to end the work week. The cold front will bring rain to central Indiana mid week. Believe the high clouds could slow temperatures a bit, but readings should still get to near record values with 850mb temperatures reaching around 15 degrees C.
The UA ridge that has been dominate across the Four-State region the last few days is what has been responsible for the abnormally warm/near record breaking temps. The center of the said ridge will be shifting east towards the southeastern CONUS today courtesy of a Pacific UA disturbance moving across southern OR/northern CA, hence promoting southwest flow aloft. So although the ridge will not be directly overhead, its influence will still be felt with 850 mb temps of 15-17 degrees C yielding the possibility for near record breaking warmth once again today. Concurrently, a weak UA disturbance across south central TX early this morning is progged to lift northeast along the western periphery of the ridge, nearing the area this aftn and wane whilst moving across the western zones this evening/tonight.
1039 AM EDT Tue Nov 1 2016 High pressure will continue to ridge across the area at the surface and aloft providing continued dry conditions and some gusty easterly winds in the afternoon and evening hours. Winds will again surge to cautionary levels especially offshore after sunset this evening as high pressure continues to ridge across the area.
