259 PM CST Thu Nov 19 2020 Shallow moisture transport ahead of the surface trof which has moved into central Kansas this afternoon has resulted in 45-50F dew points across south central and southeast Kansas. A weak cold front will drop southward and merge with the trof tonight. Otherwise, it will be a much cooler day with temperatures still a bit above seasonal climo.
(This evening through Friday) Afternoon water vapor imagery shows an upper level ridge over Texas resulting in another unseasonably warm and dry day.
204 PM CST Thu Nov 19 2020 Tranquil weather conditions once again across the Tennessee Valley as high pressure centered across the Southern Appalachians has continued to promote a clear sky and SSE flow.
Anomalous 500mb heights continue to dominate the weather pattern, which is true for much of the CONUS outside of a trough over the Pacific Northwest. Temperatures will slowly decrease each day beginning tomorrow as the ridge weakens.
At the surface, a weak cold front is draped across southwest KS, and this boundary will move through the remainder of our area over the next several hours as a weak upper level disturbance embedded within the flow traverses the northern plains pushing the front southward. Locations south of this boundary will see afternoon highs reach into the low 80s, while north of this boundary, strong daytime heating will still support upper 70s. This weak low will then move east just south of KS during the day on Friday maintaining the north winds, and highs on Friday will be much cooler with most areas staying in the upper 50s to lower 60s.
/issued 944 AM CST Thu Nov 19 2020/ High pressure as expected has shifted a little to the east and is now centered over the Mid-Atlantic states. High pressure is centered along the mid Atlantic coast this morning low pressure is in the central plains. An upper ridge extends from northern Mexico and across the northwest gulf coast.
Tonight and Friday The main concerns in the short-term portion of the forecast will be spotty light mixed precipitation over the far north late tonight into Friday, and a return to cooler temperatures. A cold front was moving through northwest WI this afternoon. The cold front will move through the forecast area this evening, reaching the far southeast portion by around midnight. On Friday, much cooler temperatures are anticipated, with highs ranging from the middle 30s northwest to the middle 40s southeast.
Increased rain chance and cooler temperature can be expected for the start of the new week. Dry weather continues as the ern CONUS is under the influence of a broad ridge with zonal flow over the Upr OH Valley Region.
For today, the influence of the high will keep skies clear, conditions dry, and maintain an easterly component to the wind.
The story over the next couple of days will be for cooler temperatures and deceasing chances of precipitation. Friday at this point looks cooler but seasonable.
/Tonight through Thursday/ Thermal ridging across the area today has allowed for southwesterly winds to usher in warm air well above average for this time of year. Meanwhile a strong cold front moving across the northern plains today has made it into northwest Iowa early this afternoon. The cold front will continue to push across the state this evening and overnight, but with a lack of moisture the area will see a dry frontal passage. The impacts will not be totally transparent, however, as winds shift to northwesterly and temperatures on Friday remain in the upper 40s to mid 50s - some 15 degrees cooler than today. This weekend a deepening low across the southern plains will help to increase moisture transport into the midwest a head of a deepening western trough.
1014 AM MST Thu Nov 19 2020 Current surface analysis shows low pressure over central SD, with a relatively weak cold front moving through southern portions of the area early this morning. Another cold front hangs to the north of the region. Cooler air behind the passing front will allow highs to range from near 50 across northeast WY and the higher Black Hills to the 60s over much of the southwest and south central SD plains. Cooler air will continue to slide south across the region into Friday, with highs mostly in the 40s to around 50 and some 30s over the higher Black Hills.
Strong high pressure will be centered to the north northeast of the region through Friday, with some weakening Friday afternoon. A few weak inverted troughs are expected to develop over the coastal waters, and move ashore through Friday. Convergence associated with this trough will help develop showers, with isolated to scattered showers affecting eastern half of forecast area.
After a cool start, temperatures are warming quickly throughout the area and already up into the 50s, and well on their way to the low 60s on the Plateau and mid to upper 60s elsewhere. High pressure is anchored over the Carolinas today with warm, dry air funneling into Middle Tennessee.
Dry and cooler. Tonight: A cool front arrives overnight switching winds to the northwest and bringing a cooler airmass into the dvn cwa. Friday: A cooler day with partly to mostly sunny skies as high pressure will be centered in the Dakotas.
This will allow for slightly cooler temperatures on Friday with highs ranging from 50 to 60 and increasing clouds in the afternoon.
Snow showers will occur over the mountains but amounts will remain light with the highest peaks seeing 1-2 additional inches overnight. Friday night will be slightly cooler with temperatures west of Big Timber dropping into the teens and areas east dropping into the 20s.
A weak cold front will sag across central and southern Utah today. High pressure aloft will bring drier conditions to the area for the upcoming weekend. Ahead of this trough, a reinforcing cold front made its way into northern Utah overnight, increasing low-level convergence into the existing boundary near central Utah. This is mainly affecting the higher elevations of northern Utah, as the low levels are not particularly moist. As the trough starts to shift east of the area this afternoon, the showers will wind down while the surface boundary shifts into southern Utah. Across portions of northern Utah, this is not too much warmer than current morning temperatures, due to overnight cloud cover maintaining mild overnight mins.
Winds and higher dew points will once again lead to a mild night, with sheltered valleys tending to be cooler, though not as drastically so as last night. Much above normal temperatures will continue Friday as a shallow cold front approaches from the north.
An upper level ridge will continue to persist through the near term over the region. At the surface, a ridge of high pressure settles over the eastern seaboard, nosing into the region from the northeast.
A broad upper trough will pass through the forecast area today, with numerous showers over the mountains and scattered to isolated coverage elsewhere. Additional snow accumulations will be light, with up to an inch in the mountain valleys and 1-4 inches on the higher peaks.
SHORT TERM (Now through Friday Night): Persistent 500 mb and surface ridging will prevail over the RGV throughout the short term period.
307 PM EST Thu Nov 19 2020 Despite today being a sunny and slightly warmer than normal, gusty southerly winds and very dry air has been the focus of today. By tomorrow morning, the entrance region of the low-level jet should be exiting to the northeast.
The Pulley Ridge buoy in the Southeast Gulf is reporting 9-foot seas, while Satan Shoal buoy (outside the Reef near Sand Key) has 5-foot seas. Strong high pressure over the U. Mid-Atlantic region today will extend into a ridge from the southern Appalachians to north of Bermuda by tonight.
and mid- level high pressure centered over Texas and the Gulf Coast will continue the dry and humid weather through Friday. With high pressure in place temperatures will also continue to rise, with afternoon highs on Friday expected to be near 80 degrees from the Rio Grande Plains to the I-35 corridor and points eastward.
Ridge begins to build to our west late in the short term period, setting up a weekend of dry weather. The GFS is keeping the area dry with zonal flow and orographic snow showers in the west while the Euro is bringing trough and associated low through the area for Thanksgiving. Drier air will push in from the west on Friday and a ridge of high pressure builds over Idaho for the weekend.
1033 AM PST Thu Nov 19 2020 An unstable upper level trough will remain over the Inland Northwest for one more day resulting in more rain and snow showers, especially near the Cascade Crest and into the Idaho Panhandle.
Winds have shifted to the east-northeast, which will help bring in some increasing cloudiness and slightly warmer temperatures over the coming days. Average mid-November temperatures expected today and tonight, then further warming up into the weekend with daytime highs in the low 80's and overnight lows in the low to mid 60's. Strong high pressure off the mid-Atlantic coast ridges southwest over Florida and into the eastern Gulf of Mexico producing gusty east-northeast winds around 20-25 knots with higher gusts. High pressure ridges over the region through the period.
Current satellite overhead and upstream suggests enough filtered sunshine today for highs to get into the low 60s most places. DDV (Issued 323 AM CST Thu Nov 19 2020) Today and Tonight: Gusty wind are expected to persist through the morning hours as the low level jet lifts across the region. The low pressure system in Ontario will continue to move northeast through the morning, keeping the tight pressure gradient over the Great Lakes Region. As the low pressure system exits this afternoon and the LLJ moves southeast out of the state, winds will begin to tamper off. The warm temperatures are expected to continue today with highs in the low 60s.
One such impulse is in the process of advecting through the region with an associated cold front. Cooler, but seasonal conds can be expected through the weekend. Another upper trough will push through the region Sat night, with most associated precip remaining south and east of the FA.
As the trough axis has progressed into the region, the surface pressure gradient has relaxed with wind speeds running generally 10-25 MPH with gusts up to 35 MPH across east central KS. Ahead of this trough axis, an unseasonably warm afternoon was ongoing with temperatures will into the 70s.
/Today through Friday night/ Warmer and breezy today and still working on afternoon highs. Southerly winds have boosted the min RH levels and have also pushed temps warmer into the mid to upper 70s. Tomorrow will be warmer to start, ranging in the 50s with a blanket of clouds developing. We will be slightly cooler in the day with morning clouds intercepting early heating, but still low to mid 70s for high temps.
High pressure will remain in control through the short term forecast period. Temperatures will continue to be warm through Friday night, with highs in the low to mid 80s and lows in the low to mid 60s.
Increased rain chance and cooler temperature can be expected for the start of the new week. Dry weather will continue overnight as high pressure is maintained underneath zonal flow aloft, with only high clouds continuing.
Despite today being a sunny and slightly warmer than normal, gusty southerly winds and very dry air has been the focus of today. By tomorrow morning, the entrance region of the low-level jet should be exiting to the northeast.

856 PM CST Thu Nov 19 2020 (Issued 900 PM CST Thu Nov 19 2020) Winds have relaxed across southern Wisconsin this evening as the pressure gradient weakened ahead of a slow moving cold front currently dropping southeast into south-central Wisconsin.
Long wave troughing is pushing off to the east and that will let weak upper level ridging build in for Friday into the weekend. Mostly clear skies prevail by the afternoon tomorrow as the upper ridge builds in.
722 PM EST Thu Nov 19 2020 Latest RAP model has mid/upper ridging across the south-central and southeastern states and the Gulf of Mexico through most of Fri. Weak troughiness in the Atlantic will drift in toward the Bahamas during Fri. At the surface an axis of high pressure resides from the Atlantic to the Deep South and spills down across the Gulf and FL. The high pressure begins to ease Fri and allows the gradient to relax some. In addition this moisture along with the mid/upper troughiness near the Bahamas could support scattered showers.
High pressure will continue to slide east as a cold front will slowly sink south.
Lows Friday night will be in the lower to mid 20s.
An associated cold front is currently crossing the area with a wind switch to the northwest. Weak cold air advection is lagging behind this cold front across western SD this afternoon. Surface ridging will build into the area tonight behind the front with light winds and lows in the mid 20s to lower 30s. Today's cold front will become stationary from OK to western TX Friday with light winds and surface ridging continuing to dominate our weather. It will be cooler Friday north of the Southern Plains stationary front, but still expect highs to range generally in the 50s.
Temperatures overnight will be a little warmer despite mostly clear skies and light winds. Temperatures will drop into the lower 40s in the northeast to the lower 50s in the southwest by early Friday morning. Warmer than average temperatures will persist through the weekend as subtropical ridging sets up over the Gulf Coast.

445 PM CST Thu Nov 19 2020 A weak cold front was positioned along the Interstate 35 corridor at 20Z with a slight decrease in temperature behind it. Further northwest, a secondary cold front was seen across northern MN extending to near the ND/SD border. Overall, Friday will be cooler as 925mb temperatures drop about 10C from today. The cold front will bring a colder air mass into the region as a longwave trough develops over the upper Midwest.
/issued 319 PM CST Thu Nov 19 2020/ Unseasonably mild conditions will occur to end the work week and into the weekend as a high pressure system off the Mid-Atlantic ridges into the forecast area.
The San Luis Valley is a bit cooler with upper 50s to lower 60s so far. At the surface, a cold front will drop southwest across the Plains, bringing with it northerly winds after sunset. This will keep cooler air in place on the Plains, where highs will only reach into the 50s. If low stratus remains in place, it may be a few degrees cooler than what is in the current forecast.

A relatively weak and dry cold front will move through the southern Texas Panhandle around sunrise tomorrow morning, reaching the I20 corridor by early afternoon.
An upper trough will keep a few showers in the area through Friday.
327 AM EST Fri Nov 20 2020 We'll have another warm and breezy day today with south winds behind high pressure over the Southeast. Warm advection clouds will form this afternoon ahead of an approaching cold front in a corridor of 1000-800mb moisture stretching from the southern Plains through the Ohio Valley to New England. Thicknesses will be a little lower today than yesterday, and with the afternoon clouds, will go for high temperatures a couple degrees cooler than yesterday despite the continued south winds. Tonight the layer of low level moisture will deepen slightly as the cold front drops down to the Ohio River. With overcast skies tonight will go warm for overnight lows ahead of the front in central Kentucky, around 50 (cooler in sheltered valleys in the Lake Cumberland region). still several degrees warmer than normal.
Early this morning, upper level flow remains relatively flat with a weak wave across the Southeast US and ridging extending offshore the western Atlantic. Friday will continue to remain dry today as the area remains between ridging at the surface and a front remains well to the north and west. Southerly flow will help to advect a warmer airmass into the region today and overnight with high and low temperatures above normal.
A slow moving trough/front will drop down into the northern CWA today and continue to slowly sink southward tonight. Highs today will be in the mid 60s to around 70, followed by lows in the mid 40s (north) to the low 50s (south) tonight.
242 AM CST Fri Nov 20 2020 High pressure will remain over the southeast U. , with a cold front to our north and west moving slowly toward the area today. Clouds will be on the increase as well as we moisten up in the lower levels.
Winds are much lighter this evening with the light wind conditions contributing to cooler temperatures area wide.
Meanwhile a weak cold front will move into SE NM-NW PB then slowly edge a little farther s Sat AM into cntrl PB, then retreating nwd Sat PM under said semi-zonal flow. High temps are likely to be a few degrees cooler Sat across most areas with increased clouds. Thereafter a fast moving and deepening shrtwv trof will move across the High Plains pushing a more respectable cold front thru ern NM and wrn TX Sun AM/PM. By 12Z Tue the next mid-level trof will be INVOF 4-Corners area and will sweep across NM into W TX by 00Z/Wed with an assocd Pacific front and result in what will likely be windy/very windy conditions. Fri there are fairly large model discrepancies wrt the cold front/trof timing and orientation, regardless either Fri or Sat cold air looks to arrive.
1032 PM CST Thu Nov 19 2020 (This evening through Friday) Afternoon water vapor imagery shows an upper level ridge over Texas resulting in another unseasonably warm and dry day.
Clouds will begin to increase late tonight into the day Friday ahead of approaching cold front across NE OK/NW AR with MVFR conditions possible. At mid evening a cold front was slowly sagging southward into the Oklahoma Panhandle. dewpoints were in the lower 50s and temps were in the low/mid 60s for the CWA at mid evening. the cold front is expected to continue its slow progression south/southeast and overtake a weak dryline currently over Western Oklahoma. a low level moisture plume from the Texas Gulf Coast into the CWA should aid in dewpoints remaining in the low/mid 50s overnight. Even with the high RH/low dewpoint depressions.
335 AM EST Fri Nov 20 2020 High pressure remains in place over the area keeping the flow moderately SE with weak winds around 5 mph.
