1238 PM EST Sun Nov 7 2021 High pressure brings dry weather through the first half of the week, with a slow warming trend. The next chance for rain arrives late in the week, as a cold front approaches. A high pressure system will provide dry weather tonight and Monday. Went on the lower side of MOS and NBM guidance at most locations for tonight based on overnight lows the past several nights. Monday should essentially be a cloud free day with temperatures in the low to mid 60s across the lowlands and mid to upper 50s across the higher elevations.
157 PM MST Sun Nov 7 2021 A gradual cooling trend takes place this week as high pressure gets weakened.
342 PM EST Sun Nov 7 2021 Beautiful day across eastern KY, with mostly clear skies and temps in the lower 60s this afternoon. The models are still generally too high with dew points, so will continue to go towards the lower end of guidance for the next couple days.
Surface dewpoints in the lower 50s are lurking across South Texas and some patch fog will be possible across the I-10 corridor right around sunrise Monday morning as this moisture advects north into the area.
Scattered to broken mid level clouds clearing everywhere except the lower Magic Valley by 07/22Z.
The ridge won't move much over the next 24 hours, so warm southerly flow will continue tonight through Monday night.
In the wake of a weak weather system that brought rain and snow to mainly Southwestern Montana, skies have largely cleared as high pressure slides into the area. Across the plains, winds will remain elevated and gusty as the high pressure system slides into the area, but winds should remain below High Wind criteria. As we head into the day on Monday, another weak low pressure system will slide north of the region, bringing another round of snow showers to the Rocky Mountain Front and some gusty winds to the plains early in the day.
923 PM EST Sun Nov 7 2021 High pressure will remain in place across the region through mid week.
With an exception of a few high clouds moving southward to troughing off of the southeast coast, no weather of consequence was occurring around the region. Forecast MOS GFS/LAMP low temperatures were mostly in the lower 40s, with the NAM in the upper 30s. Think a cooler side to this which is in the current grids (mid to upper 30s) looks like a good call. Temperatures will warm back above seasonal normals early this week as a deep layer stacked ridge axis shift east through the region.
Gradient winds have significantly diminished over the past 3-4 hours at all sites including the coast, as the low pulls further away from the area. We should again see lows reach the upper 40s to lower 50s, and some normally cooler spots toward northern Lake and NW Volusia could dip into the mid 40s. Northerly flow aloft with Florida between a ridge extending from TX/LA toward the Great Lakes and low pressure just east of the Carolina coast will keep a steady stream of dry air into the region. This will give us plenty of sunshine, and temperatures will also rebound into the lower to mid 70s for afternoon highs.
745 PM MST Sun Nov 7 2021 Cold front is currently heading south across far eastern Wyoming and northern Nebraska. High temperatures Monday are expected to be 15-20F cooler. Current forecast is on track, but will adjust the winds for the cold front to arrive a few hours earlier than previously expected. While winds are relatively light across the lower elevations, the high country has seen gusty winds and a few areas of critical fire danger this afternoon. A weak cold front will sink south into the plains tomorrow morning, which will end our stretch of very warm temperatures and start a period of cooler weather. Mild conditions will continue across the high country.
High pressure at 18Z was centered near Vicksburg MS with a ridge axis extending north-northeast into the OH valley. Frost will also be more limited, mainly over southern TN and some of our cooler valley locations in north AL. Temperatures will warm back above seasonal normals early this week as a deep layer stacked ridge axis shift east through the region.
Only area that looks like it may see more than patchy, localized frost is the same area that saw freezing temperatures this morning so I don't plan on initiating any Frost Advisories at this time.
Temperatures tonight will be near seasonal normals with lows ranging from the mid 40s to the lower 50s.
Dry conditions and warm temperatures will continue this afternoon before a trough of low pressure move across northern California early in the week bringing cloud cover and cooler temperatures to most areas.
A flat mid-level ridge will continue across the region through the short term forecast. Energy traveling through that ridge is expected to pass over the CWA tonight and Monday. Critical thickness progs over the region suggest mostly rain with the overnight pcpn, but sfc temps down into the lower and mid 30s allows for some light snow. Highs on Monday are kinda tricky, but with most guidance giving highs in the low to mid 50s, will settle with those numbers.
454 PM MST Sun Nov 7 2021 Mean NE Pac upper trough will continue to support downstream active progressive flow with an overall cooling trend in the period. Cold front continues to progress south across the region this afternoon with a period of breezy north winds continuing on the plains east of the BH. Dynamic cooling and cool temps to start will likely favor all snow with light accums expected in this corridor, esp given cool wet bulbs in the low 30s. The majority of the precip with this system looks to remain east of the FA, outside of some light rain or high elevation snow with the initial wave Tue night-Wed and light snow with the secondary cold front Thur-Thur night.
Temperatures will remain on the cooler side in the 40s and 50s throughout the week.
However, some areas are cooler than expected at this time. This warmer airmass will allow lows tonight and tomorrow night to drop only to the mid to low 40s while daytime highs tomorrow are expected to be in the mid to upper 60s. Cloud coverage is expected to increase to partly cloudy starting late tomorrow as the upper ridge begins to exit.
521 PM CST Sun Nov 7 2021 Will see another quiet overnight and will continue with the low impact weather through the short term. High pressure will slide across the area with some upper level clouds expected across the southern half of the area tomorrow with the mid level baroclinic zone and some upper support.
550 PM EST Sun Nov 7 2021 Cirrus will spill over the area within anti-cyclonic upper flow associated with broad ridging working into the region. Warm weather is then expected Monday with highs reaching the lower 60s, some 10 degrees above seasonal averages.
Upper level analysis places trough off the west coast with ridge over the southern plains into the midwest, bringing west-southwest flow over our area.
328 PM CST Sun Nov 7 2021 Will see another quiet overnight and will continue with the low impact weather through the short term. High pressure will slide across the area with some upper level clouds expected across the southern half of the area tomorrow with the mid level baroclinic zone and some upper support.
The ridge anchored in western Mexico is shifting downstream of our area with heights and thicknesses slowly receding across the desert southwest. A broad trough pushing through the region will serve to further buckle the flow with additional cooling as a weather system pushes across the Great Basin and Intermountain West north of our area.
514 PM CST Sun Nov 7 2021 Upper level high pressure will continue to dominate through the TAF cycle with widespread VFR conditions expected.
Some cooler air will push south across the area on Monday with high temperatures expected to be around 10 degrees cooler than today north of Interstate 70, with only slight cooling across the south.
Weak pressure gradients for light winds tonight and cooler temperatures with less cloud cover than the previous night.
This combined with modest mid-level ridging will have high temperatures reaching near 10F above normal for Monday.
While winds are relatively light across the lower elevations, the high country has seen gusty winds and a few areas of critical fire danger this afternoon. A weak cold front will sink south into the plains tomorrow morning, which will end our stretch of very warm temperatures and start a period of cooler weather. Mild conditions will continue across the high country.
Otherwise, VFR conditions with surface ridging producing light winds, generally less than 5kts.
616 PM EST Sun Nov 7 2021 Low pressure was along the southeast Atlantic coast, while high pressure extended from New England to Texas. The large area of high pressure is forecast to expand to the south and east resulting in a period of warming and drying.
The week will start out on the warm side with high pressure being omnipresent giving fairly benign weather.
A few of those clouds will flow over the eastern portions of the CWA and may help keep temps slightly warmer and could prevent river/valley fog in that area. Expect sunny conditions on Monday with highs in the lower 70s.
dragging upper level troughiness over FL with it and allowing ridging to build east across the Gulf of Mexico. Beyond 24 hours: High pressure dominates with dry conditions until the end of the week when an approaching cold front brings a chance of showers. High pressure over the Deep South amd low pressure offshore the Carolina coast will maintain a tight enough pressure gradient for winds in the Exercise Caution range on Gulf waters into Mon. Then the Deep South high pressure begins to slide east with winds diminishing. A cold front approaches from the west toward the end of the week with increasing winds and seas along with shower chances.
18Z data has low pressure near KHON with another area of low pressure developing in southeast Colorado. A cold front ran from the South Dakota low back into Wyoming.
A gradual cooling trend takes place this week as high pressure gets weakened.
Surface ridging will remain across the southern Appalachians overnight with a dry airmass, clear sky and calm winds allowing temperatures to drop quickly. However, height rises will produce a strong boundary layer inversion with warmer air aloft. Otherwise, VFR conditions with surface ridging producing light winds, generally less than 5kts.

VFR expected at all sites through this forecast period with mid/upper level ridging across the Southern Plains.
The region is drenched in sunshine, as the satellite imagery shows just a few high clouds moving around the northern/eastern edge of the upper-level ridge into southern IN/northern KY. Temperatures this afternoon have already reached the low 60s. Upper-level ridge drifts eastward and expands north during the day tomorrow. Heights will be on the rise and the low level flow turns more southerly.

/issued 259 PM CST Sun Nov 7 2021/ SHORT TERM (Tonight through Monday Night): Overnight Sunday into Monday, the 500mb ridge over Central Texas will move east towards the Ohio River Valley.
But with a persistent light westerly breeze and dewpoint depressions less than 10 (except in the far northwest), only made minor changes to the low temperature forecast for tonight. Upper level analysis places trough off the west coast with ridge over the southern plains into the midwest, bringing west-southwest flow over our area.
300 AM EST Mon Nov 8 2021 Dry and warmer weather can be expected under high pressure for the first half of the week. Rain is expected to return with a late week cold front.
1250 AM MST Mon Nov 8 2021 A gradual cooling trend takes place this week as high pressure diminishes.
1024 PM EST Sun Nov 7 2021 A strong, continental area of high pressure continues to build across the eastern third of the United States. Owed to differential cooling between the Florida Mainland and the warmer Florida Keys coastal waters, expecting a mesoscale high to form over South Florida again overnight tonight, which should promote a slight freshening of breezes in the late overnight hours and towards sunrise. Also expecting a wide range in low temperatures again tonight, with lows near 60 in the less insulated Upper Keys and mid to upper 60s in the Lower and Middle Keys. From synopsis, the pressure gradient due to an area of low pressure off the Georgia coastline will support moderate to fresh northerly breezes overnight.
Current radar trends suggest overnight precipitation will remain in South Dakota, but will leave a slight chance mentioned along the Highway 12 corridor. But with a persistent light westerly breeze and dewpoint depressions less than 10 (except in the far northwest), only made minor changes to the low temperature forecast for tonight. Upper level analysis places trough off the west coast with ridge over the southern plains into the midwest, bringing west-southwest flow over our area.
Surface ridging will remain across the southern Appalachians overnight with a dry airmass, clear sky and calm winds allowing temperatures to drop quickly.

/ISSUED 216 PM MST Sun Nov 7 2021/ In the wake of a weak weather system that brought rain and snow to mainly Southwestern Montana, skies have largely cleared as high pressure slides into the area. Across the plains, winds will remain elevated and gusty as the high pressure system slides into the area, but winds should remain below High Wind criteria. As we head into the day on Monday, another weak low pressure system will slide north of the region, bringing another round of snow showers to the Rocky Mountain Front and some gusty winds to the plains early in the day.
Weak cold front moves into nern OK just beyond this forecast period.
1231 AM EST Mon Nov 8 2021 High pressure over the central Gulf Coast has lead to northerly winds with VFR conditions. Winds shift some through the day to a more NNE direction as the center of the high shifts, but weather otherwise remains unchanged.
There is a weak cold front (more of a wind shift line) in nw IA that will push slowly across the dvn forecast area later today.
309 AM EST Mon Nov 8 2021 Warm, dry high pressure will dominate the weather across the region through the middle of the week.
However the low level winds will weaken later tonight under clear skies, which should allow temperatures to dip back into the 40s. As of early afternoon much of the high cloud cover has moved east, but additional variable mid and high level clouds can be expected into tonight.
237 AM CST Mon Nov 8 2021 An anomalous ridge will build over the Mid-South through today with 500 mb geopotential heights increasing up to 588 dam (97th percentile of climatology). This will result in above normal temperatures across the CWA the next few days with southerly flow resuming as the surface anticyclone finally shifts to the east. A deep trough is taking shape in the western CONUS at this time and will eventually lead to our next rain chances as a late week cold front moves across the Mid-South.
Otherwise, ridging influences sfc/aloft should provide VFR/SKC conditions thru 09/06Z.
346 AM EST Mon Nov 8 2021 The upper-level pattern remains highly amplified in the wake of a rather strong area of low pressure that continues to move out to sea. As the ridge moves closer and the gradient relaxes, winds have begun to subside, moisture has continued to fade, and skies have cleared. As the high continues to propagate eastward, the winds are expected to shift accordingly. This gradual veering should lead to the eventual return of warmer air and, eventually as the winds transition to ESE, additional moisture.
1053 PM EST Sun Nov 7 2021 Dry weather and warming temperature can be expected under high pressure for the first half of the week. Precipitation is expected to return with a late week cold front. Eastern CONUS ridging will remain dominant with warming temperature and light wind.
Another round of frost and freezing temperatures expected this morning, followed by another pleasant day. Discussion: Another pleasant weather day is expected today with temperatures expected to be a couple of degree warmer than what we experienced yesterday.
1249 AM EST Mon Nov 8 2021 Dry weather and warming temperature can be expected under high pressure for the first half of the week. Precipitation is expected to return with a late week cold front. Eastern CONUS ridging will remain dominant with warming temperature and light wind.
A noticeable ridge-valley temperature split is ongoing. Relatively higher locations with any wind at all are still in the 40s, while cooler valleys have dipped into the low to mid 30s. Upper level pattern will continue to favor dry and mild weather as quasi-zonal flow transitions to weak ridging by midweek.
Up[per ridge axis will push across the mid state today. Ridging will extend downward to the surface so sunny skies can be expected.
1221 AM EST Mon Nov 8 2021 High pressure will remain in place across the region through mid week.
153 AM EST Mon Nov 8 2021 High pressure has settled over the region and will maintain dry weather through the middle part of the upcoming week.
151 AM EST Mon Nov 8 2021 High pressure has settled over the region and will maintain dry weather through the middle part of the upcoming week.
A fairly quiet short term period with northwest flow aloft and high pressure extending across the CWA from the east. Mainly clear skies and light southerly winds will lead to mild morning low temperatures in the 40s ahead of a cold front approaching from the northwest. Behind the cold front expect winds to turn out of the north becoming a bit more breezy seeing winds around 10-20 mph throughout the afternoon and evening hours. Afternoon high temperatures will be cooler seeing mainly 60s with possible low 70s for far southeast counties depending on how quick the cold front pushes through south central Kansas.
1035 PM MST Sun Nov 7 2021 Mean NE Pac upper trough will continue to support downstream active progressive flow with an overall cooling trend in the period. Cold front continues to progress south across the region this afternoon with a period of breezy north winds continuing on the plains east of the BH. Dynamic cooling and cool temps to start will likely favor all snow with light accums expected in this corridor, esp given cool wet bulbs in the low 30s. The majority of the precip with this system looks to remain east of the FA, outside of some light rain or high elevation snow with the initial wave Tue night-Wed and light snow with the secondary cold front Thur-Thur night.
1147 PM EST Sun Nov 7 2021 Thin cirrus will arc through the area within anti-cyclonic upper flow associated with broad ridging working into the region. Warm weather is then expected Monday with highs reaching the lower 60s, some 10 degrees above seasonal averages.
The upper pattern this morning is defined by a ridge of high pressure situated across northern Mexico, with a ridge axis extending into the SE states, and a broad trough of low pressure off the West Coast. Dirty flow across the southwestern periphery of this trough importing mainly high clouds into Southeast Arizona this morning. Expect this cloud cover to clear out from west to east today as the broad trough begins to shift east. We will see this trough continue to track east, through the Great Basin and the Intermountain West the next few days as an amplified ridge develops off the coast of California and the Baja Peninsula.
549 AM EST Mon Nov 8 2021 Dry and warmer weather can be expected under high pressure for the first half of the week. Rain is expected to return with a late week cold front.
There could still be some very light snow falling in the higher mountains, but otherwise the rest of the day looks to remain quiet across the area.
525 AM CST Mon Nov 8 2021 (Today and tonight) High pressure will keep warm and dry weather settled across the area for today and tonight. Otherwise, lows will be a bit warmer for tonight as they settle into the middle 50s tonight.
Temperatures will be a bit cooler than yesterday but still slightly above normal with highs in the upper 40s to mid 50s. Tonight's lows will be in the lower 20s to around 30.
531 AM CST Mon Nov 8 2021 Weak cold front is making fast progress across the forecast area early this morning and will reach central Wisconsin by sunrise. With increased clouds and northwest winds, highs today will be several degrees cooler than what they were over the weekend, ranging from near 50 in central MN to the upper 50s for southern MN and western WI.
and Tuesday The latest RAP analysis and satellite/radar imagery show a cold front moving across northwest Wisconsin early this morning. The cold front will slowly move east and reach eastern WI by midday and into southern WI in the afternoon. With winds shifting to the northwest behind the front and more cloud cover, temps across north-central WI will be cooler than yesterday's readings. Highs will range from the mid 50s over Vilas county to the low or mid 60s over the Fox Valley. Meanwhile, high pressure will build into northern WI. Temperatures will return to the lower and middle 50s.
423 AM MST Mon Nov 8 2021 The overall weather pattern will be unsettled, cooler, and windy this week (compared to last week), with periodic chances of rain/snow.
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.
Today Through Tuesday Night Early morning surface analysis shows high pressure centered to the east of Arkansas. Expect warmer temperatures today, with highs in most areas in the 70s. Warmer temperatures will continue Through the remainder of the short term.
/Issued 334 AM CST Mon Nov 8 2021/ High temps well above normal and gusty winds will continue today ahead of a shallow cold front which is currently through NW KS.
602 AM EST Mon Nov 8 2021 A low pressure system sits between the Carolinas and Bermuda and is trekking northeast. Meanwhile, an expansive high pressure is situated across the Middle Mississippi River Valley and pushing east. This has also allowed for cooler continental air to move down across the island chain this morning. Low temperatures thus far has fallen into the lower 60s across the middle and upper Keys with mid to upper 60s across the lower Keys. As the aforementioned low continues a northeast path, the ridge will settle in across the southeastern U.
310 AM 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.
High temperatures will warm several degrees above normal this afternoon into the lower 70s for most areas. Given the dry atmospheric column, the lower end of guidance was favored for afternoon dewpoints.
A trough of low pressure will move closer to the state today and tonight bringing increasing clouds and chances for rain across northwestern Nevada by late tonight.
528 AM 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.
527 AM CST Mon Nov 8 2021 (Today and tonight) Surface observations early this morning indicate a cold front is slowly moving southward into NW KS.
