Thunderstorms could linger through early tomorrow afternoon as the warm front lifts northeast. This will introduce much warmer and more humid air into the area, perhaps the most summer-like feeling day thus far this season. Expect widespread temps in the 80s and perhaps a spot in the southwest reaching 90 and dew points in the lower 60s.
238 PM CDT WED JUN 8 2016 Broad upper level ridging is over all the conus except the Pacific Northwest and the New England/east coast states. There is also a minor trough over the Four Corners region. Convection is already developing and expected this afternoon across areas generally west of the Upper Trans Pecos in and around the higher terrain. Therefore, an isolated strong storm or two in the higher terrain of West Texas and southeast New Mexico cannot be ruled out this afternoon and early evening.
Cooler and unsettled weather envelopes the region Thursday and lingers through the weekend, with high temperatures falling into the upper 60s and 70s for many locations.
Mainly dry conditions with near seasonal temperatures will persist through tomorrow before an approaching trough cools temperatures a few degrees over the weekend, mainly across the interior. Weather conditions are expected to remain generally benign and mild for the foreseeable future as a slow moving upper level trough gradually moves into the Pacific northwest through the weekend. Satellite and model data indicate that the center of this trough is currently located across the Gulf of Alaska; however, this trough is rather elongated and stretches well southwards into the offshore waters of the West Coast. A weak cold front has also currently in the process of moving through the Pacific Northwest, but its impact on weather in our region is rather minimal.
/Issued 1202 PM EDT WED JUN 8 2016/ A nearly cloudless sky will continue be the rule through the day with high pressure in control. /Issued 728 AM EDT WED JUN 8 2016/ Clear skies prevailed over the forecast area this morning as a dry cold front continued to move southeast through GA. A northwest flow aloft will continue today as an upper level high pressure ridge sets up over the central U. dry high pressure dominating across the deep south through at least the weekend and possibly beyond.
Temps have fallen to around freezing over interior western cwa where winds are light. Elsewhere, temps should start to rebound but will still be blo normal with most areas staying in the low to mid 60s. Interior east will have best chance for mins down around freezing and some frost. 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.
615 PM EDT WED JUN 8 2016 High pressure will maintain dry and cool weather through Thursday.
212 PM CDT WED JUN 8 2016 Upper trough over eastern U.
Issued by National Weather Service Flagstaff AZ 258 PM PDT WED JUN 8 2016 An approaching area of low pressure will bring an increase in southwest winds on Thursday along with continued hot and dry conditions.
214 PM MDT WED JUN 8 2016 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.
204 PM PDT WED JUN 8 2016 An upper level trough is invading the west coast which is beginning to break down the ridge that has been responsible for the higher than average temperatures over the past week. Upper level ridge remains over the Western United States this afternoon. Ridge axis will begin to shift east from the Intermountain West to Northern Plains over the next few days, putting central California in between a ridge and an incoming Pacific longwave trough with onshore flow.
132 PM EDT WED JUN 8 2016 High pressure will build in today and persist through the end of the week. A very pleasant June evening with lows dropping down to the low/mid 50s interior to 55-60 on the coast. Dry Wed thru Fri with warming temps as the slightly cooler airmass modifies.
310 PM CDT WED JUN 8 2016 Upper heights should rise thru the end of the week as a substantial ridge becomes established over the cntrl CONUS. Guidance appears to be a touch cooler but still expect highs from the mid 80s across sthrn IL and SE MO to near 90 across cntrl and NE MO into w cntrl IL.
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.
Trof still lingering across Central Florida and there is still a slight chance of a shower or thunderstorm south of a line from Ocala to Palm Coast with storm motion off towards the East at 10-15 mph, but still believe most of activity should remain just south of Marion County. Elsewhere weak ridge of high pressure is in control with drier airmass and temps well into the lower to middle 90s and just a few high clouds at times. Weak high pressure ridge will remain north of the region with weak pressure pattern in place and this will allow Atlc Coast Sea Breeze Front to push all the way inland to the I-75 corridor late in the day.
328 PM CDT WED JUN 8 2016 Warmer temps in store for the Midsouth for the latter half of this week. A broad upper level height ridge over the western U. Northwest upper level flow over the Midsouth will transition to westerly and weaken considerably under the encroaching upper level ridge. Warmer overnight minimum temps will prevail, along with afternoon heat indices approaching 100 degrees.
1158 AM MDT WED JUN 8 2016 Weak wave will be pushing across the forecast area today ushering in cooler air aloft and driving precipitable water values up to around three quarters of an inch by this afternoon. This system exits the area tonight with the ridge building back in on Thursday.
312 PM CDT WED JUN 8 2016 At H5 large ridge over the western and central CONUS with several waves rounding the ridge in Canada and moving through the northern plains. Closed low moving through Pennsylvania. The upper level ridge will strengthen further, with temperatures continuing to rise. Main feature will be ridge over the central CONUS through the weekend. Trough moving through the northern plains Thursday evening.
242 PM EDT WED JUN 8 2016 High pressure will build in from the west tonight and persist through the end of the week.
134 PM EDT WED JUN 8 2016 High pressure moving into the area will provide mostly sunny skies today.
307 PM CDT WED JUN 8 2016 High pressure remains dominant over Central Illinois this evening and into the overnight hours. Warm southerly winds pick up on the back side of ridge later tonight. Upper level ridging from the High Plains into the Canadian Rockies will flatten a bit, but at the same time, will build toward the Midwest.
416 PM EDT WED JUN 8 2016 Cool high pressure through Thursday.
348 PM EDT WED JUN 8 2016 High pressure from the Mississippi Valley will move east across the area Thursday.
340 PM CDT WED JUN 8 2016 Mid-afternoon sfc analysis shows high pressure in place across the Ohio Valley. ridging swd and maintaining a light and somewhat variable flow across the forecast area.
220 PM CDT WED JUN 8 2016 A large ridge axis at surface and aloft continues to build southeast through the Tennessee Valley region this afternoon. Temps across the area ranged from around 80 degrees in our Tennessee counties to the lower 80s across north Alabama. Under the dome of high pressure, temps will fall to comfortable levels again tonight with overnight lows ranging from the mid to upper 50s.
/issued 1121 AM CDT WED JUN 8 2016/ With high pressure bldg into area. /issued 455 AM CDT WED JUN 8 2016/ Weak cold front attempting to back door into the region this morning will slowly slip farther south to along the Gulf coast with a slight reinforcement of drier air filtering in later on today. Don't expect any relief in the temperature department as highs will climb into the lower to mid 90s under mostly clear skies with just some spotty cumulus developing during the heat of the afternoon.
This front is attached to a parent low pressure system centered near 52 degrees N, 121 degrees W. This low will continue to weaken as it swings towards the Pacific Northwest. Several disturbances, however, will push ahead of it continuing the pattern of incredibly cooler temperatures, cloudy weather, and a slight chance for a few showers.
354 PM EDT WED JUN 8 2016 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.
Currently, high pressure ridging and axis will continue to dominate this afternoon. The main weather feature is an upper low and trough currently moving across the Pacific Northwest into western and north central Montana.
With high pressure in the region, VFR flight categories are expected through the TAF period. The HRRR model performed admirably yesterday, showing high temperatures climbing into the low 90s across much of the southern half of the state yesterday and being considerably warmer than most other available guidance. Today Through Thursday Night A large area of high pressure is over the western two thirds of the country with an upper trough over the eastern third. The upper ridge will spread eastward through the period and will encompass much of the country by Thursday night. With high pressure in control. Temperatures will continue in the mid 80s to lower 90s for highs and in the lower to mid 60s for lows.
18Z TAFs Broken lower clouds swinging across southwest Virginia in association with the upper trough over the northeastern U.
128 PM EDT WED JUN 8 2016 High pressure is building into the area which will keep VFR conditions going through the forecast period.
327 PM CDT WED JUN 8 2016 An upper level high pressure ridge will continue overhead tonight and early Thursday, while a slow moving upper trough will dig southeast to western Kansas and the western panhandle and south plains by late Thursday. RMcQueen The weak and slow-moving upper trough (currently moving through the central Rockies) discussed in the short term is projected to emerge across the southern High Plains late Thursday night before stalling out somewhere nearby through at least the first half of the weekend.
238 PM MDT WED JUN 8 2016 A weak upper trough will remain over northeast CO this evening but the QG associated with this feature in nearly neutral. increasing subsidence in the mid levels as a ridge of high pressure builds over the state. It will be warmer but increasing subsidence will likely limit the thunderstorm development in the aftn. Will keep the mention of tstms Thursday aftn confined to the higher terrain.
An axis of high pressure directly over the area is allowing these local effects to dominate. but as this moves east of the area this evening the flow will turn southeasterly under the influence of the next upstream low developing over the High Plains. Throughout the day a warm front is projected to lift north through the area. Also with the influence of the warm front. highs tomorrow afternoon should be 5 to 15 degrees warmer than today. Redevelopment is expected late tomorrow afternoon along a warm front lifting through the area. Lenning 235 AM CDT High pressure will move across Lake Michigan today with light flow allowing afternoon lake breezes to develop.
As the h500 ridge moves over the northern plains Thursday, very warm temperatures are expected across west and central North Dakota. By Thursday afternoon thunderstorms are expected to form along a weak cold front moving into western North Dakota that will finally break the cap.
226 PM MDT WED JUN 8 2016 Weak trough moving through the region today will exit to the east tonight and allow ridging to build back in on Thursday.
300 PM CDT WED JUN 8 2016 Tonight, a weakening perturbation tries to make its way east within the upper ridge and may bring some shower/thunderstorm activity into the CWA, but this will mostly likely die in our western CWA as advertised by most short term models, so not looking for a lot of precip potential. Thursday will heat up as the upper level ridge builds. We should have at least a few days with highs in the 90s, thanks to the ridge.
438 PM MDT WED JUN 8 2016 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.
233 PM EDT WED JUN 8 2016 Cool high pressure through tomorrow.
350 PM EDT WED JUN 8 2016 High pressure will build into the area from the west tonight through Thursday bringing drier and cooler weather to the region.
448 PM MDT WED JUN 8 2016 Weak trough moving through the region today will exit to the east tonight and allow ridging to build back in on Thursday.
134 PM EDT WED JUN 8 2016 An upper level trough will move east of the area today. High pressure from the Mississippi Valley will move east across the area tonight through Thursday.
448 PM CDT WED JUN 8 2016 Not much for changes to this forecast package as models continue to do well with the pattern of the upper level ridge sandwiched between a low on each coast.
407 PM EDT Sat Mar 25 2017 Southerly flow ahead of low pressure will provide warm temperatures and mainly dry weather this afternoon. Showers and a few thunderstorms will develop tonight through Sunday as the area of low pressure approaches from the west.
Surface: The low pres sys that moved thru the last couple days to the E. An axis of the high over Ontario/Quebec extended SW across Neb into CO. The Nrn portion of the front will weaken and move into the fcst area (FA) as an inverted trof. 2) Does existing stratus build down low enough? Sun: Cldy/foggy thru the AM and the low clds will probably last well into the day.
The parent upper low and its attendant short waves/PV anomalies continues to slowly advance through MO this afternoon and should only reach the IL/WI border by 18z Sunday. The only exception to this may be SE this evening were weak convection is possible near the core of the upper low. /Sunday night through Saturday/ 20z Sat water vapor imagery clearly picking up on an upper low spinning near the four corners region of the SW CONUS. more or less beginning to cluster around the ECMWF (southern) track for the track of this low and the sfc reflection.
313 PM CDT Sat Mar 25 2017 Mid/upper low pressure currently spinning over southwest MO. Weak lift associated with the trowal and low pressure is supporting isolated to scattered showers across eastern MO. These showers should linger through the early evening hours as the low lifts northeastward. The clouds should limit the radiational cooling, but winds will be relatively light as a ridge of high pressure positions over central and southeast KS. The forecast area remains dry tomorrow as a quick ridge aloft tracks over the central plains and the next system lifts out over the high plains.
231 PM EDT Sat Mar 25 2017 Above normal temperatures will prevail much of the upcoming week as high pressure offshore brings southerly winds.
313 PM EDT Sat Mar 25 2017 Cold front is currently poised to cross the Mississippi River this afternoon.
Cold front extends from eastern Montana, south to near Casper to just west of Rawlins, into northern Utah this afternoon.
Low pressure system will move in from the west during the period bringing showers and a few storms across CHA and TYS tonight into tomorrow.
The cold front was located along the Mid Texas coast into Deep South Texas and is stalling.
Weak upper trough will maintain a few light showers and flurries in northern mountains this evening. Otherwise partly cloudy and cool tonight as the trough moves eastward. System's warm front will bring light rain and mountain snow Sunday afternoon, snow level 5500 to 6000 feet MSL.
SHORT TERM (Now through Sunday night): Zonal flow will continue locally during the next 36 hours as a fast moving secondary H5 trough sweeps across the central plains. What's left of a weak cold front stalled across the northern ranchlands, bringing light north winds, but drier air remained further north.
336 PM CDT Sat Mar 25 2017 (Tonight and Tomorrow) As the upper ridge over the forecast area moves to the east through tomorrow an upper level trough will move over the Southern Plains in its wake. Morning temperatures tomorrow will be warmer with lows in the low to mid 50s. Afternoon temperatures will be 10 to 15 degrees warmer than seasonal norms will highs in the mid to upper 80s.
Rather quiet short term period as cold front pushes into marine areas this afternoon. Minor upper level ridging builds overhead tonight before the next upper disturbances approaches on Sunday.
An upper level low and short wave trough continues over the Mississippi River Valley moving slowly east with the attendant cold frontal system over Mississippi and Louisiana. The high pressure system over the western Atlantic ridges west into the southeastern coast with a surface east-southeasterly flow. The upper level low and front will drift east through tonight and approach the region Sunday afternoon and evening. Mid level impulses begin to dig into the broad ridging over the area and in combination with afternoon heating and seabreezes will help produce isolated storms mainly across inland areas. High temps reach the lower/mid 80s inland and mid/upper 70s along the coast.
In the middle to upper level(700-200 mb), latest available model streamline analysis overlaid on top of satelitte imagery as of 200 pm, depict a well defined cold core cyclone over Central Missouri. Downstream of that, the axis of a regional scale warm middle and upper ridge pokes northeastward to near 34 North 73 West from Western Cuba. And east of that, there is a well defined middle and upper level trough with its axis from near 32 North 68 West southwest to near the Windward Passage. The Florida Keys are beneath the southwestern periphery of this ridging, with moderate to fresh east winds continuing to blow across the islands and surrounding waters this afternoon. Temperatures across the islands are in the lower 80s with dewpoints in the middle 60s.
1224 PM CDT Sat Mar 25 2017 An upper low over northeast Oklahoma early this morning, will slowly eject eastward today, reaching central Missouri by 06Z tonight. A few small clusters of showers should linger mainly to the east of I-135 today, as vort lobes pinwheel around the upper low circulation. The next upstream upper trough approaching southern California, per 6. Combined with moderate- strong ascent with the upper trough, this should result in a fairly widespread convective rainfall occurring mainly in the south.
304 PM CDT Sat Mar 25 2017 At the upper levels, a west coast trough will keep the state in southwest flow through the short term. Many of the High Resolution models are showing fog from east of the Missouri River valley to the James River valley. Over the James River valley, forecast soundings show a very brief opportunity of a light mixture of rain, freezing rain, and possibly sleet Sunday morning.
there could be some precip though lingering north of the warm front. Therefore, have the highest pops across the southeastern zones. Wherever the warm front sets up will determine where the highest highs for Sunday will be located.
Otherwise, drier and cooler weather to persist through afternoon hours.
The highest winds so far on surface weather stations have been in the neighborhood of 30MPH with the squall. CIG's may locally improve behind the line, however, the surface cold front remains further west and additional RA with some TSRA is currently ongoing across central MS. SHRA will remain possible at all sites tonight through Sunday morning as the cold front moves east across the area.
1244 PM CDT Sat Mar 25 2017 Early morning water vapor imagery indicated that deep slow moving mid-level cyclone was located over northeast OK. Short term models are in good agreement this morning in taking this low across MO over the next 24 hours. The 07Z objective surface analysis indicates that the ridge axis extends from western MN into western NEb.
314 PM EDT Sat Mar 25 2017 A cold front stalls south of the region this evening. High pressure builds in overnight from the north and will shift east on Sunday.
Cooler, unsettled weather will continue for the remainder of this weekend. The next low pressure system is progged to arrive by Sunday afternoon; we have at least a slight chance for showers for much of the San Joaquin Valley north of Kern County during the afternoon.
1131 AM MDT Sat Mar 25 2017 Aviation Section Updated Splitting Pacific upper level trough continues to progress east across the western US this morning with surface frontal boundary now extending from eastern MT SW along the MT/WY/ID border. A cold front has passed through the area with drier conditions behind it.
1213 PM CDT Sat Mar 25 2017 Upper level trough/closed 500 mb low sits over the southern plains early this morning, progged to take a somewhat slow trek northeast into the eastern great lakes by Sunday night. All that said, still have the upper level low and its various ripples/spokes of energy to rotate across the region for today and Sunday. Southern stream looks fairly active, with both the GFS and the EC moving at least two 500 mb troughs from the desert southwest to the oh valley/great lakes regions. Ceilings will not improve during this period as the low level boundary layer remains saturated and look for these to be IFR through the period.
sunny skies are prevailing for just about all of the area as high pressure giving the region a nice day to dry out from yesterday's precipitation. expecting overalls highs to be slightly warmer than locales south/west. Looking for a range in daytime highs from the mid 50s to the lower 60s.
341 PM EDT Sat Mar 25 2017 High pressure continues to build southward out of Canada this afternoon.
By Sunday afternoon, an upper level trough and surface cold front will approach the area, with moisture increasing ahead of the system. Temperatures will remain near to slightly warmer than normal, with lows tonight in the low to mid 60s, and highs on Sunday in the upper 70s and low 80s.
600 PM EDT Sat Mar 25 2017 Bermuda high pressure will extend west into the Carolinas and VA through Sunday. An area of high pressure located south-southeast of central NC, and a slow moving low pressure system lifting into the mid MS Valley, will maintain warm, modestly moist, sly flow over air area tonight. A lead s/w rotating around the mid MS Valley upper low will lift newd from eastern TN into the central Appalachians Sunday, brushing our nw sector. Still, warm sly flow along with partial sun should be able to boost temperatures back into the low-mid 70s.
A closed upper low over Missouri will drift across Illinois on Sunday. It looks like there could be a lull in the precip for the late evening hours, then another round of more widespread showers is anticipated in southern WI late tonight into Sunday morning as the upper low gets closer.
333 PM CDT Sat Mar 25 2017 As of 20Z, an area of low pressure over the western Dakotas is bringing breezy southerly winds and clearing skies to the western half of the CWA. With winds becoming light again tonight, the low stratus and fog will likely push back westward, potentially reaching the Missouri River valley by 6Z Sunday. Like today, the low stratus and fog may take several hours to burn off.
327 PM CDT Sat Mar 25 2017 Cutoff low currently hanging out over central Missouri will continue to slowly meander northeastward overnight, not getting too much of a push out of here until the next low pressure system approaches tomorrow night.
