High pressure and a dry airmass allows VFR conditions to prevail.
1133 AM CST Sun Nov 1 2020 A ridge of high pressure over the Northern Plains tonight will sink southward across the area today bringing light winds and clear skies. As we move into the new work-week, a mid/upper ridge is progged to translate eastward across the central CONUS bringing rising heights/increasing thickness and rising temperatures to the region. Breezy conditions are anticipated ahead of the this system but as it moves east, we see another mid/upper ridge build into the area with above normal temperatures anticipated through the end of the work week. As we move into the weekend we begin to see a pattern change as a deep mid/upper trough builds over the western CONUS while a mid/upper ridge develops across the mid- Atlantic area.
They remain generally on pace to top out in the lower/mid 70s, though a few spots may end up warmer than forecast.
If you're noticing that northwesterly breeze this morning, then you know that cold front has let itself into Middle Tennessee. In fact, most locations are nearing their High Temperature as we speak before cooler and drier ushers in from the northwest this afternoon.
A cold front was working its way across north and central GA this afternoon as seen by clearing skies and increasing northwest winds. With high pressure building across the area. The higher elevations especially are looking at advisory criteria.
VFR conditions with mostly clear skies are expected to persist through the entire TAF period for all sites as dry cooler air moves through the area this afternoon. High pressure will push into the region at the surface level this morning. Winds will be from the north and will gradually increase to light to moderate flow as a cold front approaches the area this afternoon. With the cold front not arriving until later in the afternoon, temperatures inland will warm to the low 80s while areas along the coast and Victoria Crossroads will warm to the upper 70s. High pressure and cold air behind the front will keep lows across the area in the mid 40s to mid 50s tonight which is well below the seasonal normal. Monday will be cooler with highs in the 70s and mostly clear skies.
the lower level winds that we mix into maintain some strength. - Localized travel impacts late this afternoon into the evening Steeper lapse rates in the low levels were helping to generate some stronger snow showers. especially bridges and overpasses.
Then later tonight, conditions are forecast to deteriorate with the approach of a strong cold front.
1100 AM CST Sun Nov 1 2020 Quiet weather is expected to persist through Monday afternoon as the region sits under northwest flow aloft behind the departing trough quickly moving over the Great Lakes.
1000 AM CST Sun Nov 1 2020 Chilly temps still linger with the region firmly in the low to mid 20s. Southwest winds will pick up behind the ridge this afternoon, although not nearly as high as yesterday staying under 25 mph. With the clear skies and decreasing winds temps have falling to the lower teens at some locations. Rest of today-Monday: Upper ridge builds east into the Northern Plains and a dry/stable air mass will support dry conditions and much quieter weather. Cooler post frontal air mass is still in place today, so we have one more day of below average temperatures (30s and 40s) before the advertised warm-up starts Monday. As the upper level flow turns more zonal,and 850mb temperatures continue to rise into the teens, expect a quiet and warmer week ahead for the work week.
253 PM CST Sun Nov 1 2020 A chilly, yet pleasant fall day is ongoing this afternoon with temperatures around 50 degrees under mostly clear skies and a northwesterly breeze as the region remains on the back side of a longwave trough currently centered from Ontario southward into the southeastern US. Overnight lows are projected to drop to freezing or colder for almost the entire region (possibly remaining slightly above freezing in the more urban areas of the KC metro). Tomorrow will be a bit of a transition day as the aforementioned trough exits the region to the east and mid to upper level ridging begins to build in from the west. Winds will turn southwesterly tomorrow with some warmer temperatures returning, with highs forecasted to reach the low to mid 60s (warmer temperatures near the MO/KS border).
106 PM MST Sun Nov 1 2020 Warmer than average temperatures and dry conditions continue. The upper ridge over the western U.
Meanwhile, some CAMS models show a broad SW-NE area of low-level convergence developing this afternoon near the Lower Keys, thanks to the interaction of our ongoing easterly winds with the development of a more northerly wind over the Gulf waters this afternoon in advance of tomorrow morning's strong cold front. Have raised PoPs slightly for this afternoon, but they are still at the low end of the range of statistical guidance.
Breezy low level northerly flow continued across Eastern Oklahoma and Northwest Arkansas at mid morning in the wake of the dry cold front that moved through last night. mostly sunny skies are expected over the CWA while high pressure continues to slide across the region. this should limit the wind gust time frame with decreasing winds during the afternoon hours from north to south under high pressure. Also ahead of the approaching center of high pressure. while near the Kansas and Missouri borders temps were in the lower 50s underneath the stronger cold advection.
159 PM EST Sun Nov 1 2020 Cold front currently pushing into the southeast will quickly push through Florida overnight. Ahead of the front we have an upper level trough about 50 miles off the west coast of Florida which can be see pretty well on radar. The two features plus warmer temperatures and increased humidity is already starting to spark some isolated showers across the state this afternoon.
224 PM CST Sun Nov 1 2020 With the cold front that passed through the region overnight continuing to move off. Overnight lows tonight will bottom out in the mid to upper 20s over the eastern Ozarks to around freezing from Springfield westward as surface winds calm under the Canadian high. Heights will continue to rise as the western ridge advects eastward strengthening the warming trend that will push high temperatures above normal. A weakening closed low approaching California Monday will flatten the upper flow and reach the Ozarks by midweek.
A longwave trough extending from Ontario, Canada southward to southern Mississippi and Alabama this morning will continue to deepen slightly over the eastern conus through tonight, with the base reaching as far south as south Florida. This trough will then exit out over the western Atlantic on Monday. A surface cold front associated with an area of low pressure centered over southeastern Canada will trail across our area this afternoon, transiting east of the CWA by late afternoon. A cold front is presently draped across the region from northeast to southwest over south-central Alabama. VFR conditions prevail today with a cold front pushing across the region.
935 AM MST Sun Nov 1 2020 Warmer than average temperatures and dry conditions continue. The upper ridge over the western U.
1148 AM CST Sun Nov 1 2020 Chilly temps still linger with the region firmly in the low to mid 20s.

1149 AM CST Sun Nov 1 2020 (Today and tonight) A cold front is currently working its way southward across West Central Texas early this morning.
Relatively zonal flow transforms into a highly amplified pattern by the end of the period with a deep trough developing over the western CONUS and ridging over the east.
1135 AM CST Sun Nov 1 2020 Widespread VFR conditions are expected across the terminals through the period as high pressure builds in. Today Through Monday Night Early this morning, a cold front was pushing through Arkansas from the Plains. A large area of high pressure will follow the front tonight, and winds will diminish. Given a clear sky and dewpoints mostly in the 20s, at or slightly below freezing temperatures are expected in roughly in the northern half of the state. High pressure will begin exiting as the period ends, with a ridge to the west shifting over the region.

As of 16Z/10 AM CST, the cold front is moving across the HUN CWFA (though the exact position is a little murky). Morning cloud cover has mostly cleared up with the frontal passage, though there are still broken cumulus over the higher elevations of NE AL. In wake of the aforementioned cold front, a cold and dry airmass advects in from the northwest. Low temps overnight bottom out around or just below freezing and as a result, have upgraded the freeze watch to a warning with the latest forecast package for all of our counties.
Monday night could once again feature relatively cooler temperatures, but anticipate that a hint of a southwesterly breeze will keep things mixed up just enough to hold overnight lows generally in the mid 30s. A dominant upper ridge lifting north into Canada will extend its reach eastward across the central CONUS and remain locked in place for the next several days.
1032 AM CST Sun Nov 1 2020 A cold front has pushed through the Mid-South this morning. Highs will probably top out a couple of degrees warmer than what they are currently. A strong cold front will shift out of the area early today with strong Northwest wind increasing through the day. Despite the passing of a cold front, mostly clear skies will allow afternoon highs to warm into the mid 50s to mid 60s. Overnight, the same clear sky and dry airmass will allow temperatures to plummet to freezing or subfreezing levels across most of the Midsouth.

Upper ridging will build over the area Monday into much of the week ahead bringing back above normal temperatures.
1106 AM CST Sun Nov 1 2020 A reinforcing cold front continues its march through the southern parts of the region with even drier air spilling south behind the front. The cold front is on schedule and knocking door in SE OK and NE TX. High pressure will be arriving for most of this short term period. Speeds look to keep below Lake wind criteria, but gusts in the lower 20 mph will be common for many of us by around lunchtime today.
At this point, winds are not expected to go completely calm in most locations, but in some protected areas, the mercury could dip into the lower 20s, approaching record readings for November 2. The cold air will be short-lived, though, as winds will swing back to the southwest under sunny skies Monday, allowing both radiative heating and warm air advection to send temperatures back above freezing by 9 am to around 50 for highs.
This will induce a warming trend through the upcoming week, with tonight's sub-freezing low temperatures likely the coldest readings we will see for a week. 925-850mb temperatures moderate into the +8C to +12C range on Monday, with westerly winds and mostly sunny skies allowing for temperatures to warm into the lower 50s to lower 60s for highs. In the meantime, this week will feature abundant sunshine with highs from the lower 60s to lower 70s.
142 PM CST Sun Nov 1 2020 Cold front pushed through late last night bringing cooler temperatures off northeasterly flow. Winds should stay light tonight allowing for low temps to drop into the 30s and 40s thanks to high pressure moving into the southern plains.
