1004 AM EST Mon Nov 8 2021 High pressure will continue to build into the Southeast US today, as the strong low pressure from this weekend tracks E/NE off of the Mid-Atlantic coast. Highs this afternoon remaining below normal, in the low to mid-70s.
Low level wind shear for areas NW of the Lower Treasure Valley starting at 09/06Z through 09/16Z.
956 AM CST Mon Nov 8 2021 High clouds will gradually clear from NW TO SE today with highs in the low 50s as winds are 5 to 15mph from the west.
Light winds continue as high pressure moves overhead this afternoon and into Tuesday. Currently, temperatures are generally in the low 40s and falling gradually under a blanket of cloud cover. Dry conditions are expected on Tuesday, as high pressure drifts eastward.
Other than a few high cirrus clouds moving over the region tonight it will be mostly clear with lows falling into the low 40s and a few isolated upper 30s.
1245 PM EST Mon Nov 8 2021 High pressure has settled over the region and will maintain dry weather through the middle part of the week.
Much cooler air will spread south through the Western High Plains tonight behind a cold front pushing well south into Oklahoma. Expect afternoon highs only up into the 50s(F) to possibly the lower 60s(F) farther south along the Oklahoma border.
This will keep temperatures a little bit warmer overnight.
Southerly winds ahead of a cold front will allow for high temperatures to warm a few degrees Tuesday compared to today.
Once again we're seeing a decent ridge/valley split set up, with temps ranging anywhere from the lower/mid 40s in some of the valleys and sheltered locations, to the mid/upper 50s on the high ground and in urban areas. Other than a few high cirrus clouds moving over the region tonight it will be mostly clear with lows falling into the low 40s and a few isolated upper 30s.
Cooler air is settling in on high pressure at the surface. Warmer air on increasing southwesterly winds will help temperatures rise into the low to mid 50s.
A broad low amplitude trough will push through the Great Basin and Intermountain West north of our area over the next 36 hours. We'll see modestly cooler air filter in, resulting in several degrees of cooling over the next 48 to 72 hours.
The cold front is about to push through KAMA which will switch winds to the northeast at 10 to 15 knots starting around 00z. Cold front stalled out in the northern Panhandles will slowly track south this evening. Overall, ridge of high pressure will break down into a more zonal flow tonight into tomorrow, with cooler temperatures expected on Tuesday. Highs only expected to be in the 60s across much of the area on Tuesday, and morning lows Tuesday will be near freezing in the north to lower 50s in the southeast.
A weak cold front will sag into northwest Missouri by this evening, gradually pushing southwards through the overnight hours. This front will bring increasing cloud cover and cooler temperatures tomorrow with the possibility of some sprinkles and/or scattered light rain showers across central and north-central Missouri; however, overall chances look low and would be near and along the front as a mid-level disturbance passes by to the north.
934 PM EST Mon Nov 8 2021 High pressure will gradually build into the region through the middle of the week.
451 PM CST Mon Nov 8 2021 High pressure will dominate the forecast area through mid-week.
High pressure at the surface will continue to slowly shift east across the forecast area through the period. This, in addition to ridging aloft flattening a bit over the region and the resulting west southwest flow aloft, will yield a continuation of quiet weather across the CWA, but it'll also promote slightly warmer conditions. Still, a good bit of sun will be observed as highs range from the low to middle 70s.
537 PM CST Mon Nov 8 2021 High pressure will continue to be parked over the southeast U.
430 PM MST Mon Nov 8 2021 Parked northeast Pac upper trough will continue to support downstream active progressive flow with an overall cooling trend in the period. Initial upper trough and cold front will support some light rain and high elevation snow Wed, with some light accums possible over the Black Hills and NE WY Wed morning. Main cold front will advect through the region Thur via a potent backside clipper system, supporting strong gusty NW winds with at least adv level winds for much of the FA and possible warning levels over NW SD into west central SD given pressure gradient/rises, CAA, and BL wind progs.
/issued 451 PM CST Mon Nov 8 2021/ High pressure will dominate the forecast area through mid-week.
Clouds return to the area after sunset tomorrow evening as another upper trough moves across the Western CONUS. Due to the cloud cover, overnight lows will be slightly warmer than tonight in the mid 30s to lower 40s.
210 PM MST Mon Nov 8 2021 Parked northeast Pac upper trough will continue to support downstream active progressive flow with an overall cooling trend in the period. Initial upper trough and cold front will support some light rain and high elevation snow Wed, with some light accums possible over the Black Hills and NE WY Wed morning. Main cold front will advect through the region Thur via a potent backside clipper system, supporting strong gusty NW winds with at least adv level winds for much of the FA and possible warning levels over NW SD into west central SD given pressure gradient/rises, CAA, and BL wind progs.
(Tonight) A cold front will make slow progress across southeast Kansas tonight and is expected to remain north of the area through Sunrise Tuesday.
636 PM EST Mon Nov 8 2021 High pressure has settled over the region and will maintain dry weather through the middle part of the week.
534 PM CST Mon Nov 8 2021 A weak cold front will bring a low chance for a few showers Tuesday into Tuesday night, along with slightly cooler air.
However, a backdoor cold front that has pushed into northeast NM will continue to inch south and west this evening. MVFR to IFR cigs may develop behind this cold front along the OK and TX borders toward sunrise, potentially including at KTCC.
823 PM CST Mon Nov 8 2021 Tranquil weather across the Tennessee Valley this evening, with high pressure centered over the Deep South. For this reason, do not anticipate the threat for any frost/freeze as lows will remain in the lower 40s in most locations. Tuesday will be similar to today with the ridge axes shifting east into the lower Appalachians and southeast U.
While there was some cooling today behind the front, it wasn't overly impressive, and afternoon temperatures have climbed into the low to mid 60s in many locations. Lift associated with the trough will increase cloud cover and try to induce some precipitation Tuesday morning. Expect lows in the lower 40s and upper 30s tonight and highs in the mid to upper 50s Tuesday afternoon.
905 PM EST Mon Nov 8 2021 Dry and warm weather will be interrupted by a late week cold front. High pressure will maintain dry weather and seasonable temperature for tonight.
636 PM EST Mon Nov 8 2021 High pressure will gradually build into the region through the middle of the week.
A weak cold front will then drop south across the area overnight, supporting of veering of the winds to the north. This is due to strong warm air advection and very dry airmass ahead of a weak cold front stretched across northern lower Michigan into Wisconsin. Lows tonight will remain mild in the low to mid 40s. High pressure will quickly clear skies out Tuesday night allowing temperatures to fall into the 30s.
A quiet night and start to the day on Tuesday will occur as a transitory ridge marches across the central Rockies. Large scale ascent increases by mid-day near the UT/CO border with the arrival of a sharply curved cyclonic jet aloft followed by the main upper trough by late afternoon.
At 18Z, high pressure was centered over MS, with ridge axes northeast and southwest. Aloft, water vapor imagery and stream flow analysis also indicated a deep layer ridge axis from the northwest Gulf through the TN valley. Low temperatures will fall closer to normal in the lower 40s for most areas. Tuesday will be similar to today with the ridge axes shifting east into the lower Appalachians and southeast U.
Generally zonal flow is present across a majority of the CONUS this afternoon, outside of a positively tilted upper trough over the East Coast. A vorticity maximum over the Upper Midwest has pushed a weak cold front southward, currently stretching from northeast to southwest across the forecast area. Temperatures have warmed into the low 70s to the south of this front, with mid 60s present to the north. While temperatures will be a bit cooler, the overall air mass will not be too much different behind the front.
949 PM EST Mon Nov 8 2021 High pressure has settled over the region and will maintain dry weather through the middle part of the week.
Temps will fall into the low to mid-50s by daybreak with low 60s along the coast, as the flow becomes increasingly onshore. High pressure will continue to strengthen over the Southeast. However, increasingly onshore flow and continued swell from the strong low pressure over the Atlantic off of the coast of the Northeast could cause minor coastal flooding issues through Tuesday morning, especially in areas that experienced moderate beach erosion over the last several days.
Warmer temps have moved into the area today thanks to upper level ridging, and highs are in the low 70s for most of the mid state.
204 PM MST Mon Nov 8 2021 The focus in the short term will be on the cooler and more seasonable temperatures expected through the middle of the week behind a cold front that is currently moving through the region early this morning.
418 PM EST Mon Nov 8 2021 Dry and warm weather will be interrupted by a late week cold front. High pressure will maintain dry weather and seasonable temperature for tonight.
A quiet night and start to the day on Tuesday will occur as a transitory ridge marched across the central Rockies. Large scale ascent increases by mid-day near the UT/CO border with the arrival of a sharply curved cyclonic jet aloft followed by the main upper trough by late afternoon.
319 PM CST Mon Nov 8 2021 A weak cold front will bring a low chance for a few showers Tuesday into Tuesday night, along with slightly cooler air.
Temperatures may be cold enough in valleys west of Missoula, in western Montana, for areas of freezing rain to develop. Be prepared for icy areas especially on bridges and overpasses.
Temperatures ranged from the mid 40s to the lower 50s. We should see more sunshine this afternoon as clouds decrease, as the wave departs to the east and a weak ridge builds into the area. This will be in response to a deepening trough moving into the Plains, with warm air advection kicking in ahead of the system.
The high pressure that's been providing us with dry weather and clear skies will be moving east across the region today through this evening. As the High passes, our winds will be more easterly, although they will remain light.
The upper pattern is defined by a broad ridge of high pressure across the Gulf of Mexico, and a trough of low pressure begining to move into the West Coast. Expect this upper trough to continue to track east through the Great Basin and the Intermountain West the next day or two as an amplifying ridge develops off the coast of California and the Baja Peninsula. Initially this should help cool temperatures the next few days as the trough axis slides though Southeast Arizona. Thereafter, a dry northwesterly flow sets up the second half of the week with the influence of the amplified ridge nudging into the area from the west warming temperatures back up the second half of the week and into this weekend.
Have updated forecast to add a little more cushion to the low temp forecast. Incoming snow storm has some pretty mild subtropical air, so snow levels will rise during the day tomorrow, but northwest wind after the low passes to the east will bring back snow showers for the end on Tue night. In the Snake River plain/eastern Magic Valley, measurable snow is only found in higher elevations than Rexburg in the I-15 corridor, and in the highlands around the INL and Craters of the Moon property, and it all appears to be less than 0.
237 AM CST Tue Nov 9 2021 A weak cold front is edging into our northwestern zones (through Friona and Dimmitt) as of 0730Z. As the trough approaches it will induce pressure falls across the eastern plains of Colorado and New Mexico. The low-level flow will respond by rapidly returning to a southerly component tonight. Decent, albeit shallow, moisture will be advected northward as the warm front lifts across the South Plains overnight.
105 AM EST Tue Nov 9 2021 High pressure will gradually build into the region through the middle of the week.
252 AM EST Tue Nov 9 2021 Current IR imagery across the lower Ohio Valley reveals mostly clear skies thanks to subsidence associated with nearby high pressure.
1215 AM EST Tue Nov 9 2021 Dry and warm weather will be interrupted by a late week cold front. Upped low temps a few degrees, as a surface pressure gradient is keeping the low levels stirred, inhibiting boundary layer cooling. No other changes needed at this time as high pressure will maintain dry weather for tonight.

Expecting differential cooling (cooling relative to the warmer Florida Bay near-surface environment) across the South Florida Mainland to result in yet another wind surge for most island communities towards sunrise.
1045 PM CST Mon Nov 8 2021 (Tonight) A cold front will make slow progress across southeast Kansas tonight and is expected to remain north of the area through Sunrise Tuesday.
1020 PM MST Mon Nov 8 2021 Parked northeast Pac upper trough will continue to support downstream active progressive flow with an overall cooling trend in the period. Initial upper trough and cold front will support some light rain and high elevation snow Wed, with some light accums possible over the Black Hills and NE WY Wed morning. Main cold front will advect through the region Thur via a potent backside clipper system, supporting strong gusty NW winds with at least adv level winds for much of the FA and possible warning levels over NW SD into west central SD given pressure gradient/rises, CAA, and BL wind progs.
Aloft, ridge continues to build over the CWA. Morning sounding denoted some pretty dry, warm air just above the surface inversion as a result of building ridge, and that air will mix down through the afternoon, continuing the modification of originally cool surface airmass into seasonably warm one, with temps 5-8 degrees F above average across much of north Georgia. Tomorrow, ridge that is overhead rapidly undergoes a wavebreak as very progressive upper level pattern pushes the next system toward the area. Before that arrives, temps during the afternoon will be even warmer, with highs into the mid 70s area wide.
916 PM CST Mon Nov 8 2021 Wx map shows cool high pressure ridge over the Gulf states this evening.
1153 PM EST Mon Nov 8 2021 A weak cold front will settle south through the area overnight with a band of stratus around 4500 feet lasting several hours in its wake as winds veer to the north. This is due to strong warm air advection and very dry airmass ahead of a weak cold front stretched across northern lower Michigan into Wisconsin. Lows tonight will remain mild in the low to mid 40s. High pressure will quickly clear skies out Tuesday night allowing temperatures to fall into the 30s.
243 AM EST Tue Nov 9 2021 Departing high pressure will continue to provide dry and warm weather today. A weak cold front may produce isolated rain showers or sprinkles tonight.
Latest model runs are no different, with the NAM/GFS/EC all still on track to drop PAC NW upper level trough across the northern plains Wed night, winding the storm system up as a +100 kt 300 mb jet digs around it. This period will be dominated by an area of high pressure that moves from the Dakotas to over Wisconsin by Tuesday evening. The high will continue the VFR conditions with the high level ceilings expected to clear out Tuesday afternoon/evening. Winds will generally be out of the north at speeds under 10 knots and should come around to the southeast on the back side of the high Tuesday evening.
252 AM CST Tue Nov 9 2021 Summary: A couple of warm days are on tap before an upper level trough sweeps through and brings stormy weather to our region before ushering in colder air behind it. Highs today and tomorrow will be cooler than yesterday, but still slightly above or near our normal for this time of year with the exceptions of north-central Kansas where it will be a bit cooler.
1041 PM CST Mon Nov 8 2021 A weak cold front will drift into Missouri tonight and continue into central Illinois on Tuesday. The cold front will stall over the area Tuesday as it's upper level short wave support outruns it to the east.
In addition, some clouds will be possible through the day as an amplified trof moves across the greater region. Farther to the south near the Oklahoma border, warmer highs in the 60s still look on track. Eventually, light southerly winds are possible by evening as a high pressure center shifts off to the northeast of the forecast area.
253 AM CST Tue Nov 9 2021 High pressure ridge will move from western Dakotas eastward today and be over eastern ND/SD this aftn.
1117 PM CST Mon Nov 8 2021 High pressure continues to be southeast of Arkansas.
308 AM EST Tue Nov 9 2021 Today Pronounced mid/upper level ridging will build in from the Gulf of Mexico, extending through the Florida peninsula.
Tranquil weather across the Tennessee Valley this evening, with high pressure centered over the Deep South. For this reason, do not anticipate the threat for any frost/freeze as lows will remain in the lower 40s in most locations. Tuesday will be similar to today with the ridge axes shifting east into the lower Appalachians and southeast U.
A back door cold front has pushed into northeast NM and has finally made its way to KTCC.
1113 PM EST Mon Nov 8 2021 Dry and warm weather will be interrupted by a late week cold front. Upped low temps a few degrees, as a surface pressure gradient is keeping the low levels stirred, inhibiting boundary layer cooling. No other changes needed at this time as high pressure will maintain dry weather for tonight.
551 AM EST Tue Nov 9 2021 High pressure centered over the southern Appalachians will slide southeast and continue to build across our area. As a matter of fact this high pressure is responsible for the latest nocturnal surge that remains ongoing this morning. The corridor of strongest winds has slowly drifted from east to west and now resides across the Gulf waters adjacent to the lower Keys where Smith Shoal Light is reporting a northeast wind near 20 knots. The aforementioned ridge will allow for winds to continue to gradually slacken as we go through the end of the week.
With an upper ridge centered over Mexico extending NE into New England as well, we have little noted on the satellite across Central Alabama or much of the SE US. Some cirrus should begin to move in from the west during the afternoon and move across C AL through early Wednesday as the upper ridge begins to flatten allowing for some ripples to move through the flow.
Latest model runs are no different, with the NAM/GFS/EC all still on track to drop PAC NW upper level trough across the northern plains Wed night, winding the storm system up as a +100 kt 300 mb jet digs around it. High clouds will scatter out briefly overnight, but increase in coverage again Wednesday morning ahead of an approaching low pressure system.
421 AM MST Tue Nov 9 2021 An unsettled weather pattern will continue through the rest of the west with cooler temperatures, windy conditions and periodic chances of rain/snow.
Another impact is the potential for some freezing rain in the lower valleys in central Idaho, specifically the Highway 12 corridor and lower valleys across northwest and west central Montana where temperatures are currently in the 20s. So prepare for some icy areas especially on bridges and overpasses this morning. The cold front will push its way through the Northern Rockies during the day with temperature falling this evening behind the frontal passage.
Another cold front is forecast to impact the terminal sites just beyond this forecast cycle.
It is worth noting, however, that afternoon highs will likely be a few degrees cooler than yesterday given the increase in cloud cover, so only have temperatures climbing into the low to mid 50s.
Very gusty winds were observed all along the North Coast with gusts just under 50 around Humboldt Bay and gusts around 60 mph along near shore ridges. After Wednesday, models are in very good agreement that upper level ridging will build over the area.
Strong wind gusts and a few inches of snow are expected on the eastern Sierra slopes, light rainfall in the northern Owens Valley, and cloudy skies and cooler temperatures for the rest of our region. Dry and warmer conditions are expected for the second half of the week as broad high pressure builds over the Desert Southwest. There has been very little movement in QPF expectations across the ensemble suite, in fact, a gradual pull back of QPF overall for anywhere that isn't the highest elevations in the Sierra.
With the low moving across southern Saskatchewan on Wednesday, the combination of an increasing pressure gradient and cold air advection will bring gusty winds to the area. Some wrap around precipitation is possible over the northeast corner of the state Wednesday night as the low moves east.
Upper trough moving inland and bringing precipitation to the central California interior this morning. Ensemble solutions agree with a broad East Pacific ridge building in over the west through the weekend.
838 AM EST Tue Nov 9 2021 Mostly dry and warm weather will continue, though a weak cold front may produce isolated rain showers tonight.
However, latest observations show saturation remains in the high levels, with the exception of Alva which is reporting broken low clouds. With cloud cover exiting prior to peak heating, temperatures for central/southern Oklahoma and western north Texas are slightly warmer than the previous package. The NAM has trended warmer; the GFS has cooled and is now more in line with the NAM. This allows the surface boundary to slowly lift north/westward as a warm front tonight into Wednesday morning. With the increased WAA, stratus will likely develop Tuesday night and mid/high clouds will increase as a longwave trough approaches.
The influence of the ridge aloft has supported another night of strong radiational cooling across the TN Valley, with current temperatures in the u30s- l40s and light/variable winds.
Today Through Wednesday Night High pressure at the surface was located over the southeastern conus this morning. Upper ridge was centered over the western Gulf of Mexico, with mid and high level moisture streaming into the region around the periphery. The ridge will contract today and tonight, with the frontal boundary gaining momentum. A mid-level trough digging down into the southern Plains will interact with the front, with scattered to numerous showers developing.
516 AM EST Tue Nov 9 2021 Departing high pressure will continue to provide dry and warm weather today. A weak cold front may produce isolated rain showers or sprinkles tonight.
945 AM EST Tue Nov 9 2021 Upper level ridging along the Appalachian chain will support exceptionally warm afternoon temperatures for today and Wednesday.
525 AM CST Tue Nov 9 2021 (Today and tonight) Weak cold front currently through NW OK will make slow progress eastward into NE OK later today with minimal impact on temperatures. Otherwise increasing cloud cover is expected to keep temps slightly cooler than recent days.
High pressure ridge will move from western Dakotas eastward today and be over eastern ND/SD this aftn.
