905 AM EDT Mon Oct 19 2020 High pressure along and offshore the eastern seaboard combined with an inverted trough moving west-northwest across south FL and the Straits is supporting a breezy northeast to east wind flow in the 15 to 20 mph range across the forecast area early this morning as a tight pressure gradient (6-7MB) between these features remains in place across the state. A 6-7MB gradient across the state between high pressure along and offshore the eastern seaboard and an inverted trough moving west northwest across the southern peninsula and Fl Straits will maintain northeast to east winds around 20 knots with higher gusts over the adjacent Gulf waters the remainder of today with Small Craft headlines remaining in place for all of the waters including Tampa Bay and Charlotte Harbor.
416 AM CDT Mon Oct 19 2020 West-southwesterly flow aloft will continue across the Tennessee Valley today, in the gradient between a subtropical ridge centered off the coast of NC/SC and a mid-level cyclone in the vicinity of Hudson Bay. The combination of light-moderate southeasterly flow an scattered patches of cloud cover will result in warmer early morning temps compared to previous days, and this should translate to highs in the u70s-l80s for most of the region.
As the previous forecaster mentioned LLWS is possible this morning through 15Z for CKV/BNA/MQY as the low-level jet increases.
519 AM MDT Mon Oct 19 2020 The Hudson Bay vortex hand analyzed on 19/00Z H500 map will be forced northward over the next 24 hours by upstream energy rotating through the large gyre of low pressure covering much of NOAM. The high level cloudiness may have something to say about this and confidence not high enough to widespread conditions and fire headlines attm.
The unseasonably warm temperatures will continue through midweek, then cool considerably for the second half of the week behind a cold front.
A pleasant day can be expected today! Winds will become more southwesterly on today as a high pressure continues to build into the west of our region. With this high pressure in place, this will suppress rain chances today and high temperatures will climb into the 80s area wide. Flow aloft will become more southwesterly across the region today, with strong high pressure centered off the coast of the Carolinas building west into the region. With the high aloft wedging itself west and over the region, rain chances will remain confined west of the CWA, along a stalled weak frontal boundary. Look for highs this afternoon to warm into the low and middle 80s.
This round looks a bit lighter, with most of the snow again expected across the higher terrain of the Absarokas and Bighorns. Otherwise, a warmer afternoon is expected, with most locations in central Wyoming experiencing a dry and pleasant day. Shower activity will decrease Tuesday morning, with a drier and slightly cooler afternoon expected across the area.
West-southwesterly flow aloft will continue across the Tennessee Valley today, in the gradient between a subtropical ridge centered off the coast of NC/SC and a mid-level cyclone in the vicinity of Hudson Bay. The combination of light-moderate southeasterly flow an scattered patches of cloud cover will result in warmer early morning temps compared to previous days, and this should translate to highs in the u70s-l80s for most of the region.
(Today and tonight) Cooler conditions will remain across the area for this afternoon. Expect highs to be in the lower 60s across the Big Country. Slightly warmer temperatures can be expected across areas near Interstate 10.
223 PM CDT Mon Oct 19 2020 The upper level pattern is characterized by broad troughing across the CONUS with an upper ridge across the western Atlantic into the Eastern Seaboard. Winds should remain around 5-10 mph tonight with high pressure centered just to the northeast across the central and southern Appalachians with low pressure along the frontal boundary to the northwest.
Earlier observations from Lewistown southeast toward Miles City and Billings indicated that mixed precipitation was in fact falling at those locations, including freezing rain and sleet. For tonight through early Tuesday morning, forecast soundings favor more freezing rain than sleet, but internal programs and HREF guidance from SPC suggests sleet will be prominent as temperatures drop and the warm nose of air aloft remains over the region.
Ridging surface and aloft will continue VFR conditions at all TAF sites with winds generally less than 10kts.

/JNE/ A pleasant day can be expected today! Winds will become more southwesterly on today as a high pressure continues to build into the west of our region. With this high pressure in place, this will suppress rain chances today and high temperatures will climb into the 80s area wide. Flow aloft will become more southwesterly across the region today, with strong high pressure centered off the coast of the Carolinas building west into the region.

Look for highs this afternoon to warm into the low and middle 80s.
234 PM CDT Mon Oct 19 2020 Latest water vapor imagery is showing one upper trough move across the Midwest that is moving east this afternoon. Another area of showers associated with the upper trough is moving northeast across eastern Missouri into southwest Illinois. Latest runs of the CAMS/RAP suggest that this first round of showers will move out of the CWA this evening as this trough moves east of the Midwest. Then the focus points toward another upper trough dropping down out of the northern Rockies. Rain will likely develop by Tuesday afternoon ahead of the system in the warm air advection pattern and continue along the cold front that will move through the area on Tuesday night.
1220 PM EDT Mon Oct 19 2020 High pressure ridging continuing over the area. Strengthening upper ridge over the Southeast will allow temperatures to climb to a few degrees above normal into the mid 70s north to near 80 south. With the strato-cu clearing early this morning it appears that we should have greater solar insolation across the area compared to yesterday in addition to higher 500mb heights with the ridge building. While high pressure hangs on, the development of a coastal trough as well may lead to increased low clouds once again, although there is considerable uncertainty amongst short range guidance. Lows will be warmer, mainly in the mid to upper 50s. High pressure aloft will be centered along the Southeast U.
217 PM CDT Mon Oct 19 2020 A series of upper troughs will bring cooler wx to the region. A broad upper trough across the center of the country today will be reinforced Tuesday with a northern stream trough that moves through quickly.
240 PM EDT Mon Oct 19 2020 A cold front will stall across the region through tonight. This will allow several waves of low pressure with its associated rain to cross the region.
Thus, decreased temps to remain in the low to mid 30s this afternoon.
1259 PM MST Mon Oct 19 2020 Temperatures will remain close to 10 degrees above normal through at least the middle of the week with cooler weather arriving at the end of the workweek and into the weekend. High pressure will ensure persistent dry conditions with only occasional high clouds and periods of elevated smoke. The weather pattern remains stagnant with a longwave flow pattern nearly identical to the past several days with a stationary Hudson Bay vortex coupled with East Pacific Rex blocking. A weak subtropical jet is extending from the low pressure associated with the Rex Block to just south of the CWA.
1020 AM CDT Mon Oct 19 2020 Cold front through the area as of mid morning with areas of light rain/drizzle and some patchy fog ongoing mainly to the north of I-40. Boundary to begin lifting back north tonight and tomorrow, resulting in warmer temperatures for Tuesday.
/issued 905 AM EDT Mon Oct 19 2020/ High pressure along and offshore the eastern seaboard combined with an inverted trough moving west-northwest across south FL and the Straits is supporting a breezy northeast to east wind flow in the 15 to 20 mph range across the forecast area early this morning as a tight pressure gradient (6-7MB) between these features remains in place across the state. A 6-7MB gradient across the state between high pressure along and offshore the eastern seaboard and an inverted trough moving west northwest across the southern peninsula and Fl Straits will maintain northeast to east winds around 20 knots with higher gusts over the adjacent Gulf waters the remainder of today with Small Craft headlines remaining in place for all of the waters including Tampa Bay and Charlotte Harbor.
229 PM EDT Mon Oct 19 2020 A broad area of low pressure in the Caribbean, associated with a tropical wave, extends into the Florida straits and Florida Keys. In addition, the pressure gradient from high pressure along the eastern seaboard and lower pressure in the Caribbean is resulting in fresh to strong northeast to easterly breezes over the area.
Current satellite and obs show that the shallow cold front has stalled along our northern CWA and is beginning it's retreat northward, having made it through portions of Burnet, Llano, and Williamson counties. Weakness in the ridge aloft along the Coastal Bend will allow for a chance at some isolated shower activity for the Coastal Plains and extending into the southern extent of the I-35 corridor. Weather pattern remains unchanged through the rest of the short term with broad troughing over the CONUS and subtropical ridges over the Atlantic and Pacific basins with a weakness in the ridging aloft over South Texas.
107 PM EDT Mon Oct 19 2020 A nearly stationary front across Ohio will gradually shift back to the north as a warm front through Tuesday afternoon.
(This evening through Tuesday) Clearing has developed rapidly across the southern half of the area, allowing temperatures to warm into the lower 80s along the I-10 corridor, while remaining in the low to mid 50s along/north of I-10.
6 to 2+ inch range) associated with a surface and mid level trough moving west across the far southern peninsula and FL Straits will support areas of showers and isolated storms from the Bay area south to Fort Myers the remainder of the afternoon, with some locally heavy downpours, strong gusty winds, and occasional lightning the main hazards.
223 PM EDT Mon Oct 19 2020 A cold front will stall across the region through tonight. This will allow several waves of low pressure with its associated rain to cross the region.
230 PM CDT Mon Oct 19 2020 Tonight and Tomorrow: The short term period will remain quiet thanks to a high pressure and ridging aloft centered over the Carolinas.
