213 AM MST Wed Nov 9 2016 A strong upper ridge and an unseasonably warm and dry airmass will remain over the state for one more day.
A tranquil weather pattern will remain in place through the short term with upper level ridge dominating across Wyoming.
1239 AM EST Wed Nov 9 2016 High pressure will persist across the region today.
Early morning temperatures are slightly cooler than what we saw yesterday morning, particularly across portions of northern Lee and Eddy counties where skies are clear. A large upper trough, extending SW across the region tonight, will separate from parent trough today and retrograde back to the west as a closed low.
Very strong ridge is in place over the western portion of the country. Temperatures should be a little warmer and raised them a few degrees. Again should see plenty of sun due to strong ridge on top of us. Otherwise would like to make the lows cooler than what is in there.
Did make a small adjustment to HBG, where values were still in the lower 60s and not likely to fall much through the night.
1000 PM MST Tue Nov 8 2016 Updated Aviation section With the exception of a few high clouds, benign weather will persist as a ridge of high pressure amplifies over the area. Persistent upper level ridging will continue to restrict any chance for precipitation through the end of the week. A weak cold front looks to push through our area during the day on Thursday.
1251 AM EST Wed Nov 9 2016 Cold front passes early this morning.
251 AM CST Wed Nov 9 2016 Cool high pressure building into Illinois will provide tranquil weather for the short term period. The high resolution guidance are showing winds remaining northerly through the morning, then shifting a bit more NW this afternoon. The cooler side of that range will be along the Indiana border, where the clouds will linger and the colder mid level air resides.
427 AM EST Wed Nov 9 2016 A cold front will move through the region today bringing widespread showers that will diminish late this afternnoon and evening. Cooler conditions are in store for the second half of the week and lasting into the upcoming weekend. Sharpening 5h trof digging from the central GLAKS to western PA early this morning. Drier and cooler air will arrive into western/ northwestern sections late this afternoon. Cooler and drier air will overspread the remainder of the region tonight on brisk NNW flow. Canadien border will act to suppress persistent upper ridging of late and lead to general troffiness over the eastern third of the conus. Upper ridge may try to rebuild northward over the weekend.
458 AM EST Wed Nov 9 2016 Cloud cover will decrease by midday as high pressure builds into the southern Great Lakes. With sunshine this afternoon, high temperatures will reach the lower to middle 50s.
942 PM MST Tue Nov 8 2016 Forecast area under a large dome of high pressure this evening. Satellite showing mostly clear skies over the state as mid and high level clouds rotate around the periphery of the ridge across Idaho, southern Canada, then south across the Dakotas. Current temperatures are in the lower 40s to lower 50s and are expected to cool into the 30s to lower 40s. The amplified upper ridge currently sitting over the area will get flattened by energy streaming across southern Canada. This will increase downslope flow and cause temperatures to rise into the lower 70s for most locations.
Unseasonably strong upper ridging will hold again today, with the ridge axis right overhead.
233 AM EST Wed Nov 9 2016 Cloud cover will be decreasing today as high pressure builds into the region from the southwest.
Through the evening hours there has been patches of IFR and MVFR cigs moving across the Lower Rio Grande Valley of Deep South Texas. Most of the shower activity is expected along the immediate coastline along the developing trough with some isolated activity spreading or developing inland. The lower ceiling Wednesday morning may take much of the morning to rise to VFR. Medium confidence in the lower cigs this evening with higher confidence early wednesday. /issued 210 PM CST Tue Nov 8 2016/ SHORT TERM (Now through Wednesday night): A cold front is pushing through the CWA this afternoon and should be south of the area as well as offshore this evening. The GFS signals a touch of energy moving out of the upper low and over the Mexican mountains Wednesday night, forcing the retention of isolated showers over the Upper Valley.
The first, a cold front, will impact the area early weekend as it pushes south out of the Tennessee and Ohio Valleys. Cool, dry high pressure will settle back over the region, and a marked drop in temperatures is expected through the weekend.
Upper level high pressure remains over the western U.
A strong upper level ridge of high pressure over the western United States will persist through late in the week, maintaining dry and mild weather conditions.
Some low clouds continue behind the boundary but they are expected to clear out fairly early this morning as high pressure, currently located in the central plains, builds into the region. The high is expected to be located in the Tennessee Valley by the end of the period. Overall the upper pattern is quite amplified with an upper low over west Texas retrograding initially while undercutting upper ridging that will dominate the majority of the nation. Center of the high pressure will be over the state tonight for a rather cool Thursday morning.
High pressure will build in tonight and result in decreasing cloud cover followed by mostly clear skies for Wednesday and Thursday. It will become breezy on Thursday ahead of an approaching cold front that will move through Thursday night.
257 AM MST Wed Nov 9 2016 Upper-level ridging will promote a tranquil weather pattern across the area through the period. A slight cooling trend can be expected thru the remainder of the period w/ a cold front on Thursday, but skies will remain clear and no precipitation is expected with continuing mild conditions.
342 AM EST Wed Nov 9 2016 A cold front crosses the region today.
155 AM EST Wed Nov 9 2016 A cold front will finish moving through the region this morning, with light rain diminishing to drizzle and clouds during the day, along with much cooler temperatures. High pressure will bring a temporary dry period Thursday.
Today, after a frosty start in the 30s, temperatures should warm into the lower 60s as we mix down from around 900 mb this afternoon.
Temps a bit variable now with those that wind staying up in the low 40s and some spots with no wind in the low to mid 30s. The upper ridge with summer-like 500mb heights continues to build over the Rockies and Plains. Will continue to keep highs in the low to mid 60s, which could push the record at some locations.
/Today through Tonight/ High pressure dominates the weather pattern today into tonight and looks to provide plenty of sunshine, light winds, and slightly cooler temperatures.
Short wave trough ahead of weak cold front causing narrow band showers to form across extreme northern Tennessee and southwest Virginia early this morning. even colder in the higher eastern mountains with a freeze possible there.
201 AM CST Wed Nov 9 2016 Latest surface observations and radar imagery show that the cold front has entered northern AL.
The low will move east and quickly be forced southward as strong high pressure will be responsible for driving a cold front through the area later today with a reinforcing surge overnight. Winds will remain from a northerly direction through the day so the cold front will be noticed by the drying of the boundary layer starting around noon.
Breezy to windy conditions will occur through Thursday due to a low pressure system south of the area.
Benign weather conditions continue across South Florida with broad high pressure dominating the SE US. broad high pressure remains well in control of the region with overall subsidence and a relatively dry air mass remaining in place across South Florida through the short term. This is mainly due to a weak cold front boundary approaching the area from the north, while its parent trough moves across the eastern US.
A surface cold front moved through the region overnight and the corresponding upper trof axis will move overhead early this morning. This afternoon low level flow over the Lakes will shift from northerly more to the west as high pressure moves in from the Plains. Drier air will move in with the high as well. The Blue Grass won't get out of the lower 50s, while the Mammoth Cave region may briefly peak near 60. Skies will clear and winds will go nearly calm tonight as surface ridging takes over. Temperatures will fall into the lower and middle 30s, leading to frost formation.
1110 PM CST Tue Nov 8 2016 Cold front currently moving into nw section of the forecast area will continue southeastward early tonight and should be through most the region by 03Z. Thereafter, skies should clear out from nw to se late tonight into early Wednesday as high pressure builds east from the Plains. In fact, will need to introduce areas of frost over all but far southern counties late Wed night as clear skies and calm winds allow readings to radiate down into the lower/mid 30s.
At the surface, a fairly ill defined cold front is currently pushing through SW and Central Louisiana this morning. Aloft, an upper low is over Northern Mexico which is providing a bit of lift locally. High pressure over the plains will build into the region.
High cloud cover passing over upper ridge remains over much of the area. On Wednesday, the upper level ridge axis will move directly over the western Dakotas, likely bringing near record to record breaking warmth to all of western and central North Dakota. A flattening of the ridge will be followed quickly by northwest flow as a new ridge approaches from the west coast. A dry surface cold front will move quickly through the state Thursday morning, bringing cooler but still well above normal temperatures.
Models show 850mb temps rising to +16C to +18C across most of the FA today, which is similar to what they were late last week when record highs in the low 70s were set. Today we are starting out a little cooler, so a little hesitant about going any warmer than the mid 60s for highs.
314 AM EST Wed Nov 9 2016 Cold front passes early this morning.
352 AM EST Wed Nov 9 2016 KBYX doppler radar shows widely separated and weak echoes moving quickly westward across the Straits, well south of the Lower and Middle Keys. High surface pressure will continue to spread southward across Florida and the eastern Gulf of Mexico over the next couple of days, and have a steady eastward reach into the western Atlantic, as a cold front weakens ahead of it. The low level flow will shorten and slacken from the east, while a deep zonal flow reaches well above.
401 AM EST Wed Nov 9 2016 High pressure centered to the west will keep dry weather over the region today through Thursday.
331 AM CST Wed Nov 9 2016 A developing cut off upper low over north and central Texas will dig southwest into southwest Texas today.
SHORT TERM (Today through Thursday): 500mb tilted trough across Texas and northern Mexico will split and allow a low to cutoff across northern Mexico and west Texas today. This will provide a chance of elevated convection across the CWA today through Thursday as a coastal trough develops offshore the lower TX coast tonight into Thursday.
with the cold front dropping south through the state. The cold front will push through the rest of the state overnight. High pressure at the surface and aloft will settle into the region Thursday, with temperatures close to seasonal averages.
A cut-off upper low will carve westward over Nrn Mexico/W TX today into Thursday while mid level overrunning continues over South Central TX. The rain chances pull westward with the upper low tonight into Thursday, but mid and high level clouds will continue to extend the overrunning pattern across all counties to keep humidities up and diurnal temperature ranges down.
131 AM EST Wed Nov 9 2016 A cold front will finish moving through the region this morning, with light rain diminishing to drizzle and clouds during the day, along with much cooler temperatures. High pressure will bring a temporary dry period Thursday.
317 AM EST Wed Nov 9 2016 A weak cold front will move east from the Great Lakes overnight and early Wednesday. This cold front will bring showers to the region overnight and Wednesday. A ridge of high pressure will build northeast from the Ohio and mid Mississippi valleys Wednesday night and will remain over the north country through Thursday night.
The persistence of this higher deck across the coastal counties could delay the development of these potentially IFR/LIFR ceilings for SGR/HOU/LBX/GLS.
330 AM EST Wed Nov 9 2016 A cold front and upper level disturbance will approach from the northwest late tonight, and then sweep through the area on Wednesday. High pressure will build in from the west Thursday.
Strong ridging will continue to dominate the weather pattern keeping the region above average for the better part of the forecast, but as we get deeper into fall the troughs dropping out of Canada will create larger swings in temperatures as cooler air is pulled down. In the wake of the passing cold front, northerly winds will keep the area cooler than we've had for a few days but it won't last long.
Breezy to windy conditions will occur today through Thursday due to a low pressure system south of the area.
Amplified ridge currently over the Northern Rockies with heights to 588dm will begin to flatten today as a weak wave slides across southern Canada. This will allow for increased mixing and downslope winds, with high temperatures topping out in the lower 70s today, much above normal for early November. A weak dry cold front will cross the region tonight allowing winds to turn out of the northwest and cooler temperatures to move into the area.
Showers, and maybe an isolated thunderstorm or two, could accompany the lower ceilings. The lower ceilings will last through the afternoon, and perhaps lower to IFR at KFST. /issued 105 PM CST Tue Nov 8 2016/ The upper ridge remains over the west this morning while a low over OK has a trough extending back to the southwest. This low is expected to retrograde to the SW and become cut off tomorrow near ELP. This scenario will create the potential for additional rainfall this week before the low is eventually swept east over the weekend. will have noticeably cooler temperatures this afternoon.
300 AM CST Wed Nov 9 2016 259 AM CST A high pressure ridge just to our north shifts over the forecast area today. The high will settle over the southern U. Southwest winds increase as the pressure gradient tightens between the high and a low over Hudson Bay. Raised high temps into the low 60s.
but am expecting rain chances to diminish by 15Z Wednesday as the upper low moves farther west and impacts from the upper jet diminish.
300 AM CST Wed Nov 9 2016 The synoptic 500 mb pattern during the short term will consist of a strong ridge over the Plains and an equally strong trough centered over the East Coast. The associated cold front has moved through our region, and much of the area has cleared out. Most areas should fall into the mid 30s, and a few normally colder rural locations will drop to freezing. Milder southwest winds will develop on the back side of the high Thursday.
Upper air flow very amplified with benefit of large ridge over central CONUS through most of the week. Warming will be strongest on Thursday ahead of wave over eastern Canada and associated cold front approaches Great Lakes region. It may even be warmer.
342 AM EST Wed Nov 9 2016 A weak cold front continues to move into the North Country this early morning accompanied by a few light rain showers, and will swiftly shift through the area throughout the day.
243 AM CST Wed Nov 9 2016 Watching the radar this morning and you might see a small speck of green right along the cold front as it moves through the area.
WV imagery indicates a closed off upper level low edging westward across the South Plains of west Texas. Meanwhile, an upper level ridge of high pressure is shifting slowly eastward across the Northern Rockies and the Great Basin. Near the surface, a broad area of high pressure is sinking southward out of the Northern Plains into the high plains of Western Kansas. This is most likely to occur across the western zones, where some mid 20s are likely in the lowest Arkansas valley locations.
Much cooler temperatures can be expected tonight due to low level cold air advection, a clear sky, and surface dew points dropping into the middle 30s to lower 40s by 12Z Wednesday. GKS Cold front extending from near Springfield Missouri northeast into Central Illinois will push through the area by early evening. Some guidance members spit out a bit of precip behind the front as a vortmax which is currently over northern Missouri shifts south toward the base of the mid-upper level trof. The period begins with a trough over the eastern CONUS with a rex block over the the western two thirds of the CONUS. Kelly Cold front has shifted southeast of the taf sites this evening. SPECIFICS FOR KSTL: Cold front has shifted southeast of STL this evening.
Exceptionally dry conditions will persist across western Kansas through Wednesday night as upper level ridging moves across the Colorado Rockies into the Western High Plains during the period. Look for highs generally up into the lower to mid 60s(F) this afternoon.
1126 PM CST Tue Nov 8 2016 Upper trough will sag south of the area this evening while ridge across the western Conus begins to build eastward into the area. Concern would be for either fog or patchy frost to develop, but with center of the high well west of the area all guidance suggests boundary layer to remain mixed enough to preclude any fog or frost potential. High pressure will dominate the region through midweek.
Some very spotty areas of light rain will be possible, but most sites will be rain-free as a cold front shifts on through the region. Upper trough axis remains anchored across Southwest Texas.
The cool high pressure area will track overhead today, keeping temperatures in the upper 50s to lower 60s.
319 AM EST Wed Nov 9 2016 A weak cold front will move east from the Great Lakes overnight and early Wednesday. This cold front will bring showers to the region overnight and Wednesday. A ridge of high pressure will build northeast from the Ohio and mid Mississippi valleys Wednesday night and will remain over the north country through Thursday night.
Lows near freezing are forecast at the typical cold spots, and temps will likely fall to the mid 30s across far NE OK and NW AR. The split flow block to our west will eventually break down by the weekend as energy punches into the Pac NW and breaks down the Western CONUS ridge.
An upper level ridge axis will move directly over the western Dakotas. Compressional warming with a nearby front will combine with the ridge to yield highs in the upper 60s and lower 70s with some mid 70s in the southwest. A dry surface cold front will move quickly through the state Thursday morning. Breezy northwest winds will bring cooler, but still well above normal temperatures.
High pressure will continue to bring unseasonably warm and dry conditions along with urban haze through the remainder of the week.
316 AM EST Wed Nov 9 2016 A cold front will move through the area today.
It will turn rather breezy and mild once again as the ridge slips off to our east.
This has led to near freezing temps across much of the region, with some areas of frost. This will lead to a modest warmup for Thursday with a minor cool down expected for Fri as another surge of cooler air will drop south across the Great Lakes. Moisture is limited as this low moves across with weak forcing.
Main story for today will be the much above normal temperatures moving in under the massive upper ridge across the western and central CONUS. Cold front moves across the area late tonight with cooler air moving in for Thursday. Although, this "cooler" air will still translate to high temperatures remaining above normal for this time of year.
We are still expecting freezing temperatures for many locations north and west of a line from about Morton to Tulia by sunrise. Upper low that will be parked to the southwest of the region over the next several days will eventually kick out this weekend.
325 AM CST Wed Nov 9 2016 The synoptic pattern early this morning features an amplified flow regime, with a ridge across the western CONUS and a trough in the east. Surface ridging will nose into much of the central and southern Plains today, keeping light northerly winds in place over eastern MO/western IL. Despite the expected abundant sunshine, these winds should keep the cooler airmass in place and highs confined to the upper 50s/low 60s. Have undercut guidance across southeastern MO into south-central IL given this regime, which puts lows in the low 30s, perhaps even upper 20s in some of the typically cooler spots. Further north, as the ridge axis settles to the south, return southwesterly flow (albeit light) will commence towards daybreak.
Exceptionally dry conditions will persist across western Kansas through Wednesday night as upper level ridging moves across the Colorado Rockies into the Western High Plains during the period. Look for highs generally up into the lower to mid 60s(F) this afternoon. A quiet and dry weather pattern will persist through the end of the week as upper level ridging spreads slowly eastward into the Central Plains while a closed off upper level low remains locked in across the Desert Southwest.
High pressure over the Central Plains will overspread the region tonight as the upper trough which brought light rain last night and this morning slides by to the southeast. Wouldn't be surprised if a few local spots even flirted with the freezing mark in far northwest MO. The high pressure will move off by Thursday with southwesterly return flow developing ahead of another upper trough diving southeast through the Great Lakes.
1224 AM EST Wed Nov 9 2016 High pressure will move east of area overnight before a cold front approaches the region late tonight. Cold frontal passage will occur Wednesday. High pressure then builds in through the end of the week. Have therefore made adjustments to the low forecast to match current observations. Hi temps on Wed will be cooler than tdy due to the presence of cldnss and shwrs. The upper trof axis is forecast to move east of the down east coast Wednesday night. Thursday will be a dry day with increasing clouds in advance of the next trof approaching from the west. Clouds continue to increase Thursday night in advance a cold front and upper trof approaching from the west.
236 AM EST Wed Nov 9 2016 A cold front will cross the region today with a few showers, mainly over the mountains and higher terrain. Weak high pressure will briefly build over the area late tonight into Thursday.
353 AM CST Wed Nov 9 2016 A broad upper level trough will continue to keep the subtropical jet overhead Southeast TX today. Over the next few days, an upper low will form over northern Mexico, southern NM, and western TX. This upper low is expected to shear out and move into the plains over the weekend. Although a cold front moved through the area yesterday, the 850 mb front was well inland around the Red River Valley early this morning.
This cirrus was coming over the top of the ridge that was building over the Rockies. The ridge is compressed southward tonight as an upper level short wave begins to push southeastward through the Canadian Rockies. On Thursday, a cold front dives south through the region.
229 AM CST Wed Nov 9 2016 Latest 08z surface analysis shows high pressure over eastern Nebraska into central Minnesota. 00z GFS/NAM are in good agreement in building surface/upper level ridge axis into the Central Plains States today into tonight. as the models advect slightly warmer air into the forecast area. Southerly winds on backside of surface/upper level ridge will allow for warmer low temperatures tonight. 00z NAM is a couple of degrees celsius warmer at 925mb than the GFS/ECMWF.
