302 PM CDT Wed Oct 19 2016 A weak and diffuse cold front will move through area tonight. But cooler air will build southward into the area through the day such that temperatures will be a bit below normal with highs in the lower to middle 60s.
218 PM EDT Wed Oct 19 2016 Weak high pressure building into the area this afternoon will provide the North Country with a tranquil and mild night with areas of dense fog likely in the deeper river valleys.
230 PM EDT Wed Oct 19 2016 Warm high pressure over the region will weaken Thursday.
255 PM CDT Wed Oct 19 2016 Under mostly sunny skies this afternoon and high pressure covering much of the southeast, temps warmed well into the upper 80s. Clouds might diminish a bit as we go into the evening but with an approaching cold front, clouds will be back on the increase after midnight. This will help keep low temperatures almost 15 degrees above normal, in the lower to middle 60s. The cold front by Thursday morning will still be in southeastern Missouri but there will be enough of a weak pre-frontal trough and moisture influx to help develop a few showers, especially in NW Alabama. The highest chances for strong storms will be Huntsville west and before about 21-23z. Behind the front, temps will drop quickly with lows Thursday night dropping into the lower 50s.
High pressure will bring quiet weather and dry conditions to northern and central Nevada through the weekend.
The cold front is currently located across Kansas, northwest Oklahoma, and The Texas Panhandle. 2 PM temperature readings were in the mid to upper 80s in North and Central Texas, dropped to the low 80s near Childress, and were already in the 60s in Amarillo and Dalhart. With the cold front moving into the area tonight, the 90s will go away for a while at least. Over the next seven days, the cold front and associated rain chances are the main forecast challenge.
347 PM EDT Wed Oct 19 2016 Stalled boundary across Central Ohio tonight heads east as a cold front Thursday, exiting mountains Thursday night. High pressure for most of weekend.
235 PM CDT Wed Oct 19 2016 An unseasonably strong upper level ridge of high pressure that is bringing the very warm and humid weather conditions to the Mid South this afternoon will break down later tonight into Thursday. An amplifying upper level trough digging across the central Plains tonight will rotate through the region on Thursday along with the passage of a surface cold front.
Sfc and mid level ridge still in place across the area and will remain so throughout the day. /Issued 740 AM EDT Wed Oct 19 2016/ One more day underneath the upper ridge will result in another unseasonably warm day despite the weakening of the ridge. Digging upper trough/short wave squeezes the ridge out overnight tonight and approaches northwest Georgia during the day Thursday.
The front has pushed farther north than expected today, and subsequently the 12Z models and later runs of the HRRR are slower to bring the cold front back through the area.
149 PM PDT WED OCT 19 2016 A ridge of high pressure will allow temepratures to continue warming through at least the first part of the weekend. Satellite imagery shows a broad but low amplitude ridge extending northward into the California Coast with clear skies everywhere over the Central California Interior. Forecast models move the ridge slowly to the east over the next 48 hours or with the maximum 500 millibar heights projected for Thursday.
With 850mb ridge axis remaining across or west of the CWA in the day, clouds should remain rather abundant. The resultant temperatures will only climb into the lower 50s.
Winds will shift to the north Thursday morning due to a prefrontal trough with conditions improving to VFR by 15Z. Raised the high temperatures slightly and could see record high temperature at CRP (94).
Temperatures remain above the norm today, and that will remain the case for tonight and into Thursday before initial surge of cooler and drier air in the wake of front overspreads the region.
Cooler temperatures expected this weekend with lows in the 50s Tonight/Thursday.
As for temperatures, cold air advection will lead to cooler temps on Thursday, with afternoon highs struggling to reach 50 at most locations.
427 AM EDT FRI JUN 17 2016 Skies will continue to clear today as high pressure builds across the Upper Great Lakes region. Warmer conditions are in store through this weekend with modest humidity levels.
Overview: large scale pattern features troughing along both coasts of NOAM and sharp ridging/very warm air through the plains and just into the western Great Lakes. Temps this afternoon will warm into the middle 80s for much of the area, with the usual cooler readings near the lakes. IMPACTS: None PATTERN SYNOPSIS/EXPECTED EVOLUTION: Saturday morning, positively tilted H5 troughs sit along each coast, with a broad area of highly amplified, positively tilted ridging spanning from Baja California through Quebec. Good agreement for the ridge axis to fold through Michigan through the day Saturday.
308 AM EDT FRI JUN 17 2016 A high amplitude ridge axis, an extension of the strengthening subtropical ridge across the swrn US, will expand into the wrn Great Lakes today and tonight. Good mixing depths within the dry air will push afternoon highs into the low to mid 80s, with the northeast winds holding temps several degrees cooler along Lake Huron. Southern Mi will remain under the influence of the upper ridge through the weekend.
This high, along with ridging aloft, will provide mostly clear skies today outside of a few potential cu popping up this afternoon. * None A high amplitude ridge axis, an extension of the strengthening subtropical ridge across the swrn US, will expand into the wrn Great Lakes today and tonight. Good mixing depths within the dry air will push afternoon highs into the low to mid 80s, with the northeast winds holding temps several degrees cooler along Lake Huron. Southern Mi will remain under the influence of the upper ridge through the weekend.
The EC and GFS models are initially in good agreement on the persistent closed upper low pressure area spinning off the Oregon coast. Several short waves are rotating around the low which will continue to bring showers to the area. The upper low will begin to eject off to the northeast Saturday.
Air temperatures and heat index values should be several degrees cooler today and tomorrow compared to the last few days, providing a welcome respite from the recent string of hot/humid conditions where heat indices exceeded the century mark on successive days.
306 AM EDT FRI JUN 17 2016 High pressure will slip down out of Canada and into New England today. As it drifts offshore on Saturday, a westerly flow will transport warmer air into the area.
1136 PM MDT THU JUN 16 2016 A very warm and generally dry period of weather can be expected over the next several days with upper-level ridging in place.
620 AM EDT FRI JUN 17 2016 High pressure will slip down out of Canada and into New England today. As it drifts offshore on Saturday, a westerly flow will transport warmer air into the area.
400 AM EDT FRI JUN 17 2016 A cold front will push southeast through the region today and tonight.
While the upper level high continues to dominate the weather across the area.
355 AM CDT FRI JUN 17 2016 Morning analysis has upper level ridge dominating the plains. A trough off the pac NW coast with another one over New England and the mid Atlantic. Clear skies with generally light winds, however temps remain very mild due to the thermal ridge over the region. a trough is positioned from a low in S Dakota to the sw towards the front range. A cold front is still to the west. Behind the trough yet ahead of the cold front along with a low level jet will continue to bring the chance for thunderstorms. A strong area of upper level high pressure continues to dominate the weather across western and north central Nebraska, as well as much of the central and southern plains and desert southwest.
122 AM EDT FRI JUN 17 2016 Low pressure near Pittsburgh will move southeast off the Carolina coast by morning. This will allow high pressure to build over the region for the weekend. The showers have ended in the Toledo area and the remaining showers will move south during the early morning hours as the upper trough moves southeast. Not much to write about in the short term as high pressure will dominate Friday through the weekend.
548 AM CDT FRI JUN 17 2016 Another quiet and seasonably mild night is underway across the cntrl TN Valley this early Fri morning, as strong high pressure at the sfc continues to make its way into the mid/srn Atlantic. At the same time, a weak cold front was located from the mid Atlantic States wwd into the Midwest Region. With the oncoming weak cold front, slightly cooler/drier will begin to slowly advect swd into the region later this afternoon into the evening period. A dry and near seasonal weekend then looks to be in store for the TN Valley area, as a large dome of high pressure impacts much of the ern CONUS.
Current satellite indicates the upper level low centered just off the northern California, southern Oregon coast will continue to spin up moisture and cool air will remain in place. Just a few minor tweaks to the minimum temperatures as latest guidance suggests lows may be a degree or two cooler than the previous forecast.
The early-day convection and eastward progression of a weak short- wave trough aloft will push the surface boundary across central ND at 07 UTC southeast into SD and MN later today. However, the 00 UTC GFS and NAM suggest that mid-level capping late tonight may be stronger than modeled earlier, and the low-level jet upstream in SD is modest at 25 kt. Thereafter, the 00 UTC guidance agrees that the flow aloft shifts to the northwest as the intense subtropical ridge sprawling from the southwest US into the central Plains is flattened a bit.
(Issued 926 PM CDT THU JUN 16 2016) It's warm and muggy out there as of 9pm with temps in the lower 80s and dew points in the upper 60s to lower 70s. A cold front is laying west to east across central KY and is progged to sink south through overnight. Because of how dry, warm and muggy it is out there right now, will bring the lows up a deg or two in most locations.
658 AM EDT FRI JUN 17 2016 Clouds and a few sprinkles will linger in a post cold front environment early this morning. These clouds will give way to increasing sunshine this afternoon, with cooler and drier air filtering in as high pressure builds into the region.
1233 AM CDT FRI JUN 17 2016 225 PM CDT Fairly deep low pressure for mid-June of 1003 mb across eastern Ohio will continue departing eastward tonight with a weak high pressure ridge building in from the northwest. A large area of high pressure will move across the region Friday and Saturday.
An upper level trough of low pressure will continue to bring cooler than normal temperatures through Saturday. Building high pressure will bring a return of hot temperatures by mid week. Water vapor imagery and RAP 500 mb analysis indicated a broad upper level low system just off the coast of the Pacific northwest, which is providing increased cloud cover and cooler temperatures across the region.
Another day of below normal temperatures is forecast for central California today as the region remains in upper level southwest flow with an upper low nearly stagnant along the Pacific Northwest coastline. Subtle warming will occur on Saturday, with day time high temperatures near normal as the upper low moves slowly north northeast allowing 500 mb heights to rise.
440 AM EDT FRI JUN 17 2016 A large high pressure system, will continue to build over the region, through the weekend. Thicker mid and high-level clouds continue to push southward early this morning, as a compact upper low tracks into the Mid-Atlantic. By Sat night an impressive upper level ridge will be centered over the desert southwest and a mid-lvl ridge will be centered over much of the eastern CONUS.
The low pressure system responsible for several weather disturbances, rain and some mountain snow this past week will continue to spin off of the northwest coast. A weak ridge of high pressure will nose its way into the Northern Rockies today and provide some warmer temps into the lower 70s. Saturday that low pressure system will finally begin to move inland. The dynamic support and energy from this low and associated front will bring an increasing threat for thunderstorms across much of the Northern Rockies Saturday afternoon and evening.
201 AM PDT FRI JUN 17 2016 Low pressure will bring breezy winds and cool temperatures through this evening.
656 AM EDT FRI JUN 17 2016 Low pressure will shift southeast from the area today. High pressure over the great lakes will build across the Mid-Atlantic through the weekend.
The good news for Saturday is 1000-500mb thicknesses should decrease a bit across the eastern part of the state in response to the main upper ridge center beginning to elongate and shift northward.
347 AM EDT FRI JUN 17 2016 A cold front will push southeast through the region today and tonight.
One factor supporting this potential is that northerly flow aloft is expected to strengthen to 30 to 35 kts late tonight as the upper ridge shifts northward across New Mexico. The upper ridge axis should shift north of the area leaving us with easterly flow aloft.
623 AM EDT FRI JUN 17 2016 Low pressure will move southeast across the virginias to the mid atlantic coast early today as high pressure builds in from the north.
with the upper low center now over SE Lower Michigan. and remaining low clouds continue to gradually dissipate from north to south as high pressure and drier air build into the Western Great Lakes region. with mainly clear skies expected thru the night as high pressure and dry air thru the column build into Northern Michigan. Overnight lows will cool into the low to mid 50s. High pressure continues to build into the region with the 500 mb ridge axis in the Upper Midwest, west of the Upper Great Lakes at 12z, expect things to be dry and warm. One thing to note is that the ridge lays over so that it is in the forecast area by 12z/Saturday. with the 500 mb ridge laying over, and somewhere in or south of the forecast area, the forecast becomes a little problematic.
400 AM EDT FRI JUN 17 2016 Low pressure has tracked into eastern North Carolina. High pressure over northern Michigan will build across the Mid Atlantic through the weekend.
307 AM MDT FRI JUN 17 2016 Upper level ridge axis will roughly extend from El Paso to Minneapolis today. There is a weak trough embedded in the southwest flow over eastern Colorado. This will bring slightly cooler temperatures today and increase low level moisture. Thinking the warm mid levels and cooler surface temperatures will make it difficult for thunderstorms to form today and tonight. A strong upper level ridge will be oriented southwest to northeast across CO through the weekend.
143 AM EDT FRI JUN 17 2016 High pressure builds down from Southeastern Canada through Friday, then remains over the area through the weekend.
Flat short wave ridge will pass through our area from the southwest today making today about 10 degs warmer than yesterday in our southern zones, and about 15 degrees warmer in northern mountain areas where it was rainy yesterday. The main upper trough off the northwest coast will pivot one final short wave trough through our area Saturday. This short wave trough can already be seen as an area of clouds in the Pacific near 35/130. The trough will support a surface cold front that will move eastward across our zones Saturday with a chance of showers and thunderstorms and breezy post-frontal west/northwest winds. Saturday will be about 5 degs cooler than today. The cold upper level trough lifts northeast across the Pacific Northwest states Saturday night, bringing a few showers to the higher terrain of southeast Oregon and southwest idaho.
An 850 mb ridge was located over the northwest gulf and 850 mb temps were 24c at CRP and 22C at LCH. The upper ridge begins to push N-NW towards the 4 corners region. This creates just enough of a weakness for a weak inverted trough to undercut the ridge and slide into SE TX. A weak upper level disturbance on the periphery of the ridge will try to sneak into the region Saturday afternoon and have added PoPs for the eastern half of the region late in the day.
407 AM CDT FRI JUN 17 2016 A slight moderation in the heat for portions of the Midsouth east and north of the Memphis metro today, as lower dewpoints spread in behind a weak backdoor cold front. At 3 AM CDT, this cold front had passed through Paris, TN, with upstream dewpoints in the lower and mid 60s over the western Ohio River Valley. Relief from the high dewpoints will prevail areawide for the weekend.
359 AM EDT FRI JUN 17 2016 A large high pressure system, will continue to build over the region, through the weekend. Thicker mid and high-level clouds continue to push southward early this morning, as a compact upper low tracks into the Mid-Atlantic. By Sat night an impressive upper level ridge will be centered over the desert southwest and a mid-lvl ridge will be centered over much of the eastern CONUS.
A cold front will move south across the terminals this morning with winds shifting around to the north behind the front.
333 AM MDT FRI JUN 17 2016 Upper level analysis has ridge dominating the weather pattern across the central CONUS with troffing across the Pacific Northwest. The breezy north to northeast winds will bring slightly cooler temps into the area, with highs mainly in the 80s. Saturday, upper level ridge will rebuild across the northern plains bringing well above average temperatures back to the area. Upper ridge remains across the area through Saturday night, with temperatures only cooling into the 60s and 70s across the SD plains. As a quick moving upper trough moves through Canada, a cold front at the surface will push through the northern plains.
215 AM CDT FRI JUN 17 2016 Upper level ridge axis leaning over the Great Lakes over the next couple days.
338 AM CDT FRI JUN 17 2016 An expansive upper level ridge today will lead to even warmer temperatures area wide but likely shy of record levels. Furthermore, the ridge will act to suppress any convective development on top of the low level convergence along the dryline. Upper level high pressure will expand northward Saturday to near the classic 4-corners position.
/issued 816 PM EDT THU JUN 16 2016/ Ample moisture combined with a short wave dropping southeast across the peninsula and eastern Gulf waters within a mid level trough located across the southeastern states and north Florida helped to generate a good deal of showers and storms across the region during the afternoon compared to yesterday afternoon with many fast moving showers and isolated storms being observed. This upper support combined with an increasing westerly flow (between high pressure to the south and an approaching front to the north) helping to increase speed convergence along the coast should renew shower and storm development over the eastern Gulf waters after midnight with this convection then moving onshore along coast during the pre-dawn hours Friday morning.
404 AM EDT FRI JUN 17 2016 Aviation sections updated Warmth will build once again over the weekend as a broad ridge of high pressure strengthens and expands over much of the country. This ridge will prevent any precipitation through the weekend.
222 AM EDT FRI JUN 17 2016 Upper low with lingering showers today, mainly east of Ohio River.
303 AM CDT FRI JUN 17 2016 Early this morning high pressure settled into the Great Lakes region. This high pressure is the main driver of sensible weather in the short term. With high pressure centered over the Great Lakes, drier more comfortable air will lead to a nice day today and tricky forecast for tonights lows as clear sky and slackening winds could lead temps to drop to near the dewpoint tonight. With models over doing the low level moisture as of late, there is a chance that tonight could be in 50s CWA wide. The upper level ridge currently over the central plains gets flattened and nudged eastward by a upper vortex moving across Canada.
314 AM MDT FRI JUN 17 2016 High pressure aloft will bring hot mostly sunny dry weather to southern New Mexico and west Texas through this weekend. Broad upper ridge will continue its northward drift with associated high pressure aloft becoming centered near El Paso today.
602 AM EDT FRI JUN 17 2016 Upper low with lingering showers today, mainly east of Ohio River.
Latest guidance indicates this should continue on an easterly trajectory, initially moving through the high MUCAPE air mass it is in currently. Tonight looks to be a more confused picture of the convection as a trough axis will be extended across the area and areas of mid level convergence may serve as a focus for further convection over the Northland. Have gone a little cooler Saturday than Friday, as despite the extra cloud cover the strong warm air advection should help keep temperatures on the warm side. The weekend looks hot, humid, and stormy with a threat of severe weather, while cooler and drier weather will settle in for the middle of the week.
High pressure over the region is bringing nearly calm winds and clear skies. The high will slide slowly southeast across upper and lower Michigan today and tonight, resulting in dry conditions with mostly clear skies. Highs today should reach the lower to middle 80s inland, with 70s lakeside with onshore winds. Lows tonight should reach the upper 50s to around 60 in most areas, though could get a few degrees cooler with the light winds and clear skies expected.
A high pressure ridge will usher fair weather and warm temperatures into NY and PA through this weekend. We do have a zone of low level convergence running along the high terrain from roughly Cortland east through Cooperstown but not enough moisture for convection. An upper atmospheric ridge will extend through the Ohio Valley into NY/PA by late Friday, pushing warmer temperatures and fair weather into our region. By Sat night an impressive upper level ridge will be centered over the desert southwest and a mid-lvl ridge will be centered over much of the eastern CONUS.
356 AM CDT FRI JUN 17 2016 The upper level ridge, that has allowed temperatures to climb this week, will remain in place across the Central Plains into the weekend.
Upper trough initially over eastern U. will give way to upper ridging that will extend eastward from upper high centered over southwestern U.
344 AM CDT FRI JUN 17 2016 The upper ridge was in place this morning over the Central Plains. Tonight, there is some weak convergence across central Kansas within the low level jet and near a surface front. The more easterly winds do however bring a slightly cooler as well as drier airmass in and the potential for extreme heat index values continues to wane.
336 AM EDT FRI JUN 17 2016 Low pressure will move southeast across the virginias to the mid atlantic coast early today as high pressure builds in from the north.
Upper ridge remains firmly in place across much of the mid section of the country on Saturday, with the forecast area on the eastern periphery on the ridge.
629 AM EDT FRI JUN 17 2016 Skies will continue to clear today as high pressure builds across the Upper Great Lakes region. Warmer conditions are in store through this weekend with modest humidity levels.
As of 5 am, low temperatures have reached the low 80s with dew points in the upper 70s. 75 inches as a ridge of high pressure extends over Cuba and our southern waters. Even though a mass of Saharan Air Layer is expected to reach the Keys later today, lingering available moisture in the lower level and interaction with the island chain could be enough to trigger the development of isolated showers and thunderstorms near the island chain and moving northeast.
VFR conditions will dominate the period as upper ridge remains anchored over the South Central CONUS. /issued 1000 PM CDT THU JUN 16 2016/ For the 10 PM update made a few minor changes to the sky cover given current moisture wrapping around the Northeast periphery of the middle level ridge of high pressure.
