TEMPERATURES WILL REMAIN NEAR NORMAL TODAY WITH HIGHS IN THE UPPER 70S AND LOWER 80S ALONG WITH LOWS TONIGHT IN THE LOWER AND MIDDLE 60S.
311 AM CDT WED MAY 11 2016 Cold front currently moving through the Texas panhandle into far northwest Oklahoma early this morning.
UPPER LOW BEGINNING TO MOVE INTO NORTH DAKOTA EARLY THIS MORNING. PRECIPITATION SHIELD REMAINS OVER EASTERN MONTANA WITH SOME SNOW OVER THE RIDGE TOPS IN THE SOUTHWEST ZONES. THE LOW WILL CONTINUE TO DRIFT EASTWARD TODAY WITH RAINFALL TAPERING OFF DURING THE AFTERNOON. A BRIEF DRY PERIOD IS EXPECTED TONIGHT THROUGH THURSDAY MORNING AS AN UPPER RIDGE BEGINS TO BUILD TO THE WEST.
431 AM CDT WED MAY 11 2016 Moist, unstable airmass coupled with warm front lifting north into the forecast area is setting the stage for convective initiation stretching from around Cedar County, MO west-northwestward into north-central KS. Dewpoints are already into the lower 60s this morning for many locations, and upper 60s are knocking on the doorstep in southwestern KS, along with SBCAPE 1000+ J/kg analyzed there as well. Better dynamics continues to look to linger back behind the cold front coming through with a narrow corridor of better shear immediately ahead of the frontal boundary.
/issued 233 PM CDT TUE MAY 10 2016/ An upper trough is strengthening over the northern Rockies and westerly flow is over the CWA. Temperatures are expected to warm up to almost 10 degrees above normal today as southwest winds aid in compressional warming with upper ridging developing over the region. The previously mentioned upper trough will move over the central conus Wednesday with a cold front moving southward across the TX panhandle. The cold front is expected to move into the area Wednesday night/Thursday morning and will result in below normal temperatures for Thursday.
WOULD NOT BE OVERLY SURPRISED IF TEMPERATURES PUSH TO NEAR THE UPPER 80S TO ALMOST 90 DEGREE RANGE AS SW WINDS AND POSSIBLE COMPRESSIONAL HEATING OCCUR AHEAD AF AN APPROACHING COLD FRONT.
PRESSURE GRADIENT REMAINS A LITTLE SNUG WITH LEE SIDE LOW PRESSURE OVER THE SIERRA MADRE COMBINING WITH THE HOT TEMPERATURES OUT WEST PRODUCING A DECENT THERMAL GRADIENT TO KEEP THE SOUTHEASTERLIES BREEZY DURING THE AFTERNOON HOURS TODAY. THE GRADIENT IS FORECAST TO SLACKEN SLIGHTLY THURSDAY AS A FRONT MOVES INTO CENTRAL TEXAS AND MID LEVEL RIDGE BUILDS OVER THE DESERT SOUTHWEST LOWER THE WINDS.
MID LEVEL RIDGE AXIS HAS SHIFTED SWD OVER SOUTH FL AND THE KEYS/STRAITS. WITH SOME U60S IN THE NORMALLY COOLER SHELTERED INLAND SPOTS. AXIS OF ELONGATED MID LEVEL SHORT WAVE TROUGH OVER THE EASTERN CONUS WILL SLIDE EAST AND SHOULD PASS EAST OF FLORIDA DURING SAT. UPPER TROUGH WILL OUTRUN FRONT ON SAT AND CAUSE IT TO GRADUALLY WASH OUT.
236 PM MDT THU JUN 9 2016 High pressure amplifies across Colorado and will slowly shift its axis eastward over the next couple of days.
Cooler air has come in behind last night's cold front, but even cooler air will come in behind another cold front late Friday and Friday night.
Late this afternoon hot temperatures are apparent over the lower yellowstone valley where readings in the mid to upper 90s are fairly widespread. Friday will bring a brief respite as weak ridging builds back in.
An upper level ridge of high pressure extends from the western Atlantic through the eastern Gulf of Mexico, with ridging aloft extending into the southeastern U. Upper level ridging will continue to extend across the southeastern states tonight, while weak surface ridging also remains in place over much of the eastern U. Lows tonight are forecast to range from the lower to mid 60s inland, with upper 60s to mid 70s expected over southern areas near the immediate coast/ beaches. Ridging aloft gradually shifts eastward and weakens Friday as an upper level trough moves into the vicinity of Louisiana and western Mississippi. Friday afternoon highs should range from around 90 to the mid 90s, except perhaps slightly cooler at the beaches.
Latest water vapor imagery shows an upper low circulating just off of Vancouver Island with a downstream southwest flow into North Dakota. The upper level low will meander and head into Washington state Friday before ejecting northeast through southern Canada over the weekend. An associated surface cold front will advance from southern and eastern Montana into North Dakota tonight. Lcl heights will likely be a bit lower across north central ND as Minot sounding shows dewpoints in the lower 60s holding on through the evening.
Better chance for precipitation will occur later tomorrow afternoon into tomorrow night as the cold frontal boundary sags in from the northwest.
330 PM EDT THU JUN 9 2016 A warm front will bring showers mainly southwest of Pittsburgh through Friday.
324 PM CDT THU JUN 9 2016 High pressure centered over eastern Kentucky this afternoon with an extension into eastern Texas.
Raised PoPs areawide but went with the highest PoPs over the southwest zones where the RAP and HRRR indicate slightly higher moisture levels and greater instability.
125 PM EDT THU JUN 9 2016 High pressure will maintain dry and cool weather today.
332 PM CDT THU JUN 9 2016 The ridge of high pressure continued to be the dominate feature across the Central United States today. Persistence forecasting is the name of the game into the weekend as these conditions continue underneath the ridge.
248 PM CDT THU JUN 9 2016 Warm air moving into the region in earnest this afternoon and overnight as the thermal ridge over to the west broadens and shifts east. Southerly surface winds helping as well to usher the warmer air into the region.
1215 PM CDT THU JUN 9 2016 Temperatures were on their way this morning already in the upper 70s to the lower 80s. A warm front currently over the eastern CWA is the focus mechanism for convection this morning. An area of low pressure and associated cold front will slide across southern Canada late this afternoon and through the overnight hours. Thunderstorms will develop along the cold front over eastern MT and western ND where better instability and deep layer shear will be located.
1109 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.
Measurable rainfall in the form of showers is expected for portions of the west side, especially the higher terrain of the Cascades and in Douglas and Coos Counties. Temperatures on Friday will be about 10 degrees below normal for highs as a fairly cold upper level trough moves through.
235 PM CDT THU JUN 9 2016 West TX and SE NM remains on the eastern periphery of a high amplitude ridge today that extends from the Desert Southwest NE through the Central US. At the surface, lee trough and a weak dryline extends south through eastern NM resulting in breezy SE winds across much of the region and dewpoints in the 50s most locations. The upper ridge axis will begin to shift east Friday however thunderstorm chances continue as weak disturbances traverse the region through the weekend.
Other areas remained mostly sunny under the influence of the ridge. Some higher clouds noted over the Ohio Valley along the eastern periphery of the upper ridge. Should that occur, surface temperatures could be a degree or two warmer than currently forecast. Daytime temperatures Friday will be warmer than today's. Winds will generally be light and variable as the area remains under high pressure. Strengthening ridge of high pressure over the region will provide mainly dry and very warm conditions through the weekend.
618 PM EDT THU JUN 9 2016 Low pressure will continue to move east of the region tonight.
103 PM CDT THU JUN 9 2016 A weak upper level low pressure trough will gradually move over the area tonight and Friday bringing increasing thunder chances especially to the KLBB and KPVW terminals overnight. /issued 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.
237 PM PDT THU JUN 9 2016 Windy and cooler conditions expected through the end of the week and into the weekend.
253 PM EDT THU JUN 9 2016 High pressure over the region will gradually shift eastward and be off the coast by Friday afternoon.
148 PM EDT THU JUN 9 2016 Aviation After a couple of days of cool and mainly dry weather, conditions will be turning warmer and more active.
218 PM MDT THU JUN 9 2016 A ridge of high pressure will remain over Colorado tonight and Friday. The latest HRRR keeps any developing tstms this aftn and evening over the higher terrain. It will remain capped across the northeast plains but enough mid level moisture to support another round of aftn tstms over the higher terrain.
201 PM MDT THU JUN 9 2016 Early afternoon WV satellite imagery and RAP analysis shows upper level ridging across the SW US. Due to the high bases, deep melting layer, and marginal CAPE values in our CWA, confidence in severe hail is lower. Friday: H5 ridge will be centered roughly across our western CWA, with large scale subsidence and an even drier air mass limiting any thunderstorm potential. Warmer guidance is even higher. With even minor bias corrections the mean/consensus guidance shows highs in the upper 90s, and it is certainly possible for some locations to reach the low 100s.
1241 PM 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.
314 PM PDT THU JUN 9 2016 An upper level trough will bring a cooling trend through the end of the week.
343 PM CDT THU JUN 9 2016 Mid-afternoon sfc analysis shows high pressure in place across the Ohio Valley. ridging swwd and maintaining a light mostly erly flow across the forecast area attm. however am a little concerned as medium-range guidance also indicates good ridging developing over the wrn Gulf region/cntl CONUS at that time. By mid-week another upper low crossing the nrn tier is progged to drop swd around troffing over New England.
455 PM EDT THU JUN 9 2016 Quiet weather through at least most of tonight, with the only potential for precip late tonight into early Fri as a warm front lifts into the area. Models suggest that the nrn Great Lakes will remain on the periphery of a mid/upper level ridge dominating the cntrl CONUS.
428 PM EDT THU JUN 9 2016 High pressure will move south and east of the area tonight which will allow temperatures to rise well above normal heading into the weekend.
444 PM CDT THU JUN 9 2016 For tonight, another round of showers and tstms developing over the higher terrain in ern NM and srn CO and also near a sfc trof axis located in that region will head sewd into the fcst area this evening and tonight. In addition, a weak upper level low pressure system will track sewd around the ern periphery of an upper level ridge of high pressure and into our fcst area tonight, and may augment shower and tstm development.
Most of the storms are forecast to develop along the high terrain near Lost Trail Pass through Butte and then become strong as they move off to the east. Skies will briefly clear through the late evening before increasing again tonight ahead of the next cold front. Friday looks to be another shower and thunderstorm day with a cold front passage.
1230 PM CDT THU JUN 9 2016 Surface map early this morning has a warm front arching from southern SD through north central IA. Otherwise, temperatures early this morning ranged from the upper 40s/lower 50s northeast of I-94 to the lower and middle 60s along and west of the Mississippi River. Models show the warm front lifting to along the I-90 corridor by this afternoon/early evening. Thinking there will be redevelopment this afternoon into this evening along the warm front with daytime heating and as moisture transport increases/impinges on the frontal boundary. The warm front pushes northeast of the I-94 corridor on Friday with fairly stout capping taking place behind the front.
308 PM CDT THU JUN 9 2016 Gulf of Alaska closed low with trough along the west coast. Large ridge into the central conus with upper wave moving through the central plains and close low over the Canadian Maritimes with trough along the eastern seaboard. This should move a pseudo cold front into Western Nebraska Friday.
107 PM CDT THU JUN 9 2016 High pressure ridge has slipped off to the east and an upper level disturbance has moved through the region north of ILX. 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.
/issued 235 PM CDT THU JUN 9 2016/ West TX and SE NM remains on the eastern periphery of a high amplitude ridge today that extends from the Desert Southwest NE through the Central US. At the surface, lee trough and a weak dryline extends south through eastern NM resulting in breezy SE winds across much of the region and dewpoints in the 50s most locations. The upper ridge axis will begin to shift east Friday however thunderstorm chances continue as weak disturbances traverse the region through the weekend.
South-southeast winds will continue, with the higher speeds and a few gusts to near 20 knots at KABI this afternoon. For our area, we remain under upper level ridging with a weak upper level low near the Gulf Coast that continues to cause some scattered afternoon and evening showers and thunderstorms. In addition, daytime heating is resulting in afternoon showers and thunderstorms across the higher terrain west of our forecast area.
A high pressure ridge will continue to drift eastward allowing moisture to move up into Arizona from the south.
Southwest flow will continue across the region through the weekend as an upper trough deepens along the west coast. Moisture working north ahead of this trough will start to spread into Utah Friday night and remain in place through the weekend.
1109 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.
153 PM EDT THU JUN 9 2016 High pressure will settle across the region today and tonight, then move offshore on Friday. Today: Clear skies and very comfortable temperatures this morning as high pressure settles in directly overhead. Highs this afternoon in the low to mid 80s with dewpoints in the very comfortable upper 40s to lower 50s range. Given airmass modification with the lack of any advection, we should see low temps a bit warmer than this morning.
Tonight Through Friday night Upper level ridging is building overhead and will remain situated atop Arkansas through the short term period. Expect to see the CU a little further east tomorrow afternoon as high pressure continues to slide east of the state, and Gulf moisture makes headway into Arkansas.
322 PM MDT THU JUN 9 2016 Early afternoon WV satellite imagery and RAP analysis shows upper level ridging across the SW US. Due to the high bases, deep melting layer, and marginal CAPE values in our CWA, confidence in severe hail is lower. Friday: H5 ridge will be centered roughly across our western CWA, with large scale subsidence and an even drier air mass limiting any thunderstorm potential. Warmer guidance is even higher. With even minor bias corrections the mean/consensus guidance shows highs in the upper 90s, and it is certainly possible for some locations to reach the low 100s.
129 PM EDT THU JUN 9 2016 High pressure to our west builds across the area through the end of the week.
As advertised, the upper level ridge across the rockies has started to move across the plains, or closer to our area. Temperatures across the Lower Missouri River Valley have risen for the most part into the upper 80s to lower 90s this afternoon. The upper level ridge will continue to slowly push eastward through the weekend. At this point, it appears the highest heat indices will remain just under advisory criteria with some locations reaching 100F certainly not out of the question. Globals indicate the ridge will begin to breakdown by the end of this upcoming weekend.
404 PM EDT THU JUN 9 2016 High pressure will build across the region through Friday.
319 PM CDT THU JUN 9 2016 A weak upper level low pressure trough from western Kansas through the Texas Panhandle and western South Plains will very slowly edge east tonight and will be atop the area on Friday. The upper trough overhead certainly will be a valid reason for at least a low thunder mention Friday afternoon, but if showers persist well into the day Friday that will minimize development until very late in the day.
1236 PM CDT THU JUN 9 2016 The heat is on! Upper ridge axis stretched well into central Canada at 06Z with scattered pockets of convection over central and western Nebraska. One thing to note in tonights model runs however is a faster translation of the initial ridge axis to the east compared to past runs. At this time POPs remain on the low end but adjustments may be needed in later forecasts if similar trend shows up in the drier models.
346 PM 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.
314 PM EDT THU JUN 9 2016 Low pressure will continue to move east of the region tonight.
324 PM EDT THU JUN 9 2016 High pressure will remain overhead before moving offshore on Friday, initiating a warming trend for the weekend. Temperatures will be quite a bit warmer in the mid to upper 80s with highest values in the southwest.
322 PM CDT THU JUN 9 2016 Current WV imagery showing an upper low off west coast of BC/WA and an upper wave exiting Alberta into Southern Sask, with southern extend of wave over NW MT/Nrn ID. Temperatures will be similar tomorrow to today although far northeast may be a couple of degrees cooler depending on morning precipitation and cloud cover. Surface winds begin to shift northerly late Sat Friday night as a ridging from a Canadian high (over W Central Sask) extends into ND. This will result in much cooler overnight lows generally in the upper 50s across the northern zones.
Issued by National Weather Service STATE COLLEGE PA 149 PM EDT THU JUN 9 2016 Temperatures will remain cool today under a northwest flow before gradually moderating Friday as high pressure moves into the region.
A high pressure ridge will drift eastward allowing moisture to move up into Arizona from the south.
Expect dry weather for tonight as high pressure remains in control. Lows will range from the lower 60s in the east to the mid 60s west. Broad upper ridging will continue over the region on Friday. with isolated afternoon and evening showers/storms mainly south of the Highway 84 corridor. Highs Friday will once again be in the low to mid 90s. Lows will be warmer.
230 PM MDT THU JUN 9 2016 Upper ridge is centered over the CONUS, with a closed low over the Pacific Northwest. Chances increase this evening as weak wave/cold front being to push through the CWA. Flattened ridge sharpens on Friday behind this wave, and thermal ridge rebuilds.
247 PM EDT THU JUN 9 2016 Weak high pressure will build through Friday night.
310 PM CDT THU JUN 9 2016 (Tonight and Friday) An upper level high will shift northeast across the Four Corners area overnight into Friday.
(Issued 1029 AM CDT THU JUN 9 2016) This morning was pleasant with overnight lows ranging from the lower to upper 50s across the TN Valley which is several degrees below normal.
1123 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.
956 AM EDT Fri Oct 14 2016 Strengthening high pressure will build down the East coast Today, reinforcing the onshore flow pattern. Morning sounding shows a deep layer of dry air above the lower layer, so do not anticipate showers this afternoon over land. Building high pressure from the North will reinforce the onshore flow.
A small area of showers w/ a few thunderstorms continues to move E from extreme SE KS to extreme SW MO as a weak mid-level trof moves E toward Ern OK. Sat-Sun: Garnering the greatest attention by far is the rapid warmup that'll occur as a result of a very slow, ewd-moving lwr-deck trof that'll venture into the Central Plains. Combined with strong, massive high pressure covering the Sern U. Mon: With the massive high pressure continuing to cover the Sern U. the upstream, strongly sheared, trof will remain situated from Ern Nebraska to SE CO. The sharp, positively tilted wave, though shearing, will push a cold front SE across KS Mon Night with the front likely exiting SE KS Tue Morning. The remainder of the work-week should be nice as weak high pressure follows in its wake.
A broad continental high pressure cell persists across the eastern United States. weak upper level ridging persists across Central America and the Western Caribbean. Water vapor imagery depicts a nebulous pattern across our latitude, while a positively tilted short wave trough presses east through the southern Plains. Although the lower tropospheric profile appears favorable for precipitation (see 12Z KKEY RAOB), we feel our vertical profile has modified since the early morning launch.
/issued 429 AM CDT FRI OCT 14 2016/ Axis of a positive tilt trough had cleared all but our far southeast counties before daybreak. Brunt of scattered to numerous storms ahead of this trough have been poised along and just north of I-20 for much of the pre-dawn hours. Trend is for this activity to remain outside of our CWA, but will keep an isolated shower mention in our low Rolling Plains until the trough exits by mid/late morning. Despite subsidence and drying aloft behind the trough axis, a widespread stratus shield will hold strong for most of the morning. Height rises and breezy SW winds ahead of lee troughing in NM don't look to offer much additional warming thanks to moist boundary layer winds ahead of the trough.
657 AM CDT Fri Oct 14 2016 At 08z, a little higher based stratus starting to sneak up into the lower Missouri valley, an offshoot of larger mass of stratus to the south. Northward push today will be a bit problematic as gradually increase mixing, especially for the lower stratus forming across central KS pulled northward with strong southerly low-level jet. A nicely sheared layer atop the low level moisture suggests that drizzle will be possible, and perhaps even some fog as stratus lowers toward areas of higher terrain near/east of I-29. Kept highs a little cooler over northwest Iowa where it looks like the stratus will hang in the longest. Cooler air will settle in Saturday night which should erode the stratus and push it to the southeast.
