549 AM CDT Thu Oct 24 2024 (Today) An upper trough axis will shift east from the Great Lakes to the north Atlantic Coast today, and a cold front will move south through the Tennessee Valley this morning. Afternoon highs will change little, still reaching up to the low to mid 80s.
Expect the western valleys to be largely socked in with low clouds come sunrise and some local fog and freezing fog in the Rogue and Illinois valleys. High pressure and low level offshore should still allow for clearing and temps rising to within 5 degrees of normal today.
Otherwise, high pressure remains in control through this weekend, and above average high temperatures continue.
Temperatures will warm today and Friday under upper level ridging. With residual moisture from yesterday's light rain, there are areas of valley LIFR with fog and freezing fog, mainly in southwest Oregon. The main updates this morning are to issue a Small Craft Advisory for Friday afternoon and evening, preceding a strong cold front, and then with the front, upgrade the Gale Watch to a combination Gale Warning in the outer waters north of Cape Blanco and Hazardous Seas Warning for the remainder of the waters. A thermal trough near the coast will bring moderate north to northeast winds today through tonight, with steep seas in the outer waters south of Cape Blanco.
As the upper trough continues to shift eastward, a cold front will move southward through our region tonight which will finally bring an end to our stretch of record heat. Compared to today, temperatures Friday will be much cooler and closer to seasonal averages with highs in the 70s area-wide. Winds will remain on the breezy side through early afternoon, but will gradually diminish by Friday evening as surface ridging builds into the region.
230 PM MDT Thu Oct 24 2024 KEY MESSAGES: * After gusty winds this afternoon, expect a calm gradual warming trend under a building high pressure ridge over the next several days - through this weekend. WEATHER PATTERN OVERVIEW: A rather un-eventful forecast is in store for our region as the upper-level flow pattern showcases a broad weak ridge of high pressure slowly building in from the south and southwest over the next 2 to 3 days.
334 PM EDT Thu Oct 24 2024 - Cooler conditions prevail for the rest of the work week and into this coming weekend.
111 PM EDT Thu Oct 24 2024 A cold front continues to move across the North Country this morning with an isolated shower or two possible through daybreak.
Unfortunately, limited moisture is expected with this front, therefore, rain chances will be on the low side.
(This evening through Friday) High pressure was building southward over the Ohio and eastern Tennessee Valleys this afternoon behind last nights cold front. Temperatures were only a few degrees cooler than yesterday at mid afternoon in the 70s. Friday looks to be another mostly sunny day but a low pressure area over the mid Mississippi Valley will pull up the front to the south and increase moisture in the western areas or plateau in the afternoon. Temperatures will still warm rapidly into the mid 70s to lower 80s across the lower elevations and 60s in the mountains.
1225 PM CDT Thu Oct 24 2024 Latest surface analysis had a stalled dry cold front across northern Mississippi. Under near full insolation and a light wind this afternoon, temperatures will top out warmer than normal and relative humidities will drop lower than normal. An upper-level trough approaching the U. West Coast will see a building downstream ridge move across the Rockies and central CONUS over the weekend.
Patchy valley LIFR (ceiling and vis) may return to west side locations again tonight with the highest probability being in the Umpqua Basin (including KRBG). Temperatures will warm today and Friday under upper level ridging. The main updates this morning are to issue a Small Craft Advisory for Friday afternoon and evening, preceding a strong cold front, and then with the front, upgrade the Gale Watch to a combination Gale Warning in the outer waters north of Cape Blanco and Hazardous Seas Warning for the remainder of the waters. A thermal trough near the coast will bring moderate north to northeast winds today through tonight, with steep seas in the outer waters south of Cape Blanco.
1228 PM EDT Thu Oct 24 2024 A front swings through the morning with high pressure briefly building in on Friday.
There will certainly not be any cooler air to speak of today, as a 500mb ridge axis will set up from Louisiana northward into the Great Lakes region. A weak upper trough will move just off to our north by Friday evening, but the only weather we'll see from that feature may just be high cirrus clouds.
The additional moisture will tighten up our spreads from lows to highs, unlike the desert like air of late with these warm days and much cooler mornings. We should settle warmer tonight with some mid to upper 50s and a few lower 60s.
Aloft, South Florida remains on the southern periphery of a transient mid-level trough pushing across the eastern United States acting to reinforce dry air via 500mb northwesterly flow. Overnight lows will be in the mid/upper 60s to low 70s for interior and Gulf coast areas, and the low to mid 70s for the east coast metro.
Now with the higher RH back, we are headed for a successful add 10 degrees at 10 LST (11amCDT)for a range of highs, some new records or at least ties.
1224 PM CDT Thu Oct 24 2024 (Today through Friday) Near normal temperatures and generally rain-free conditions will prevail through the period as broad mid-level ridging continues to influence the region. 9 inches, will approach the Lower Texas Coast this afternoon.
So high pressure at the surface and aloft, along with northwest flow and warm air aloft, will maintain a dry and stable air mass.
157 PM EDT Thu Oct 24 2024 High pressure will lead to dry and seasonable temperatures today. Warmer temperatures are expected on Friday along with a chance of showers as a cold front approaches from the west.
(This evening through Friday night) High pressure will remain in place across the region.
1237 PM CDT Thu Oct 24 2024 Near record heat will continue across the Mid-South through Friday before a cold front moves through.
(Rest of today through Friday) Thanks to a cold front passage overnight, today's temps are running 5 to 10 degrees cooler than yesterday. Yet readings are still warmer than normal. High pressure centered over the Ohio Valley will stay in control the rest of today with sunny skies and temps mostly in the 70s.
Isolated to scattered convection which developed north of a warm front was dissipating over our far northeast CWA. The surface warm front was lifting northeast over our western CWA. Temperatures were in the mid to upper 80s on the southern side of the warm front with dew points near 60, while north of the front, temperatures were in the low 70s in the northeast CWA to the upper 70s closer to the front. This will also bring a surface cold front into the area late tonight. Highs will be cooler behind the front, but West Plains will flirt with record highs. Friday night: A cooler air mass will then work into the area Friday night with lows dipping to more normal readings for this time of year in the mid to upper 40s.
A weak cold front will move through the region Friday morning into the afternoon hours, resulting in north winds and slightly cooler temperatures.
WV imagery shows an upper trough digging into the central CONUS this afternoon, and this will drop a cold front into the region overnight. For those who like cooler weather, Friday is your day, and the coldest day this forecast as highs average only ~ 5 F above normal as highs in the north struggle in the 70s.
221 PM EDT Thu Oct 24 2024 High pressure building overhead will allow for dry conditions to prevail through Friday.
Analysis charts show weak high pressure over the Deep South and the Gulf of Mexico. Temperatures are currently in the mid 60s to low 70s inland and in the upper 60s to mid 70s near the coast with dew points in the low 60s to low 70s. Afternoon highs in the low to mid 80s are forecast with mostly to partly sunny skies. Weak high pressure over the northern Gulf coast will continue north to northeasterly winds over the waters, but wind speeds will be a little lighter around 10 knots.
The higher resolution models are trying to crank out some light precipitation tomorrow night around Island Park and maybe south toward Bear Lake, as a weak wave races across the state.
1047 AM CDT Thu Oct 24 2024 - Temperatures will be warmer than normal for the rest of the week, with highs toward the end of the weekend 20 to 25 degrees warmer than normal. A low pressure system and an associated weak front will move west to east across the Plains today. Temperatures will be slightly cooler on Friday behind the cold front, topping out in the 50s for highs, but remain about 5 to 10 degrees above average for late October. Friday evening, we are in northwesterly flow aloft with a ridge moving in from the west.
- Cool and Sunny This Weekend Ridging and high pressure will keep conditions mostly sunny to sunny over the weekend. However, thermal troughing overhead will keep temperatures near normal for this time of year. It will be a bit warmer at the immediate lakeshore given the lake is still warm.
1215 PM CDT Thu Oct 24 2024 - Slightly warmer and breezy conditions over the first half of the day will lead to high fire danger. TODAY & TONIGHT: Another slightly cooler and breezy day is ahead! Taking a look across the area, mostly cloudy skies with high cirrus continues to progress overhead this morning mostly in response to the increasing warm air advection (WAA) with the weak ridging aloft. With lingering WAA aloft and southerly surface flow in place, expect our temperatures to likely top out in the low to upper 60s and low 70s for the day. With this in mind, expect a much cooler night with overnight lows dip in the low to upper 30s with the coldest conditions likely along the Hwy-14 corridor.
(Now through Friday) An upper ridge will continue across the southeast through tonight before moving east on Friday as an upper trough moves across the Mississippi River Valley. This will allow for a weak cold front to sag southeastward into the Tennessee Valley by late Friday.

346 PM EDT Thu Oct 24 2024 High pressure building overhead will allow for dry conditions to prevail through Friday.
While the elevated nature of the convection will preclude some of this being realized, hodographs become quite enhanced and âloopyâ as the low level jet increases with ESRH still inflating to >300 m2/s2 at times. Thermodynamically, LFCs are just below the freezing level, enhancing the percentage of positive area below freezing and in the hail growth zone, so there is the potential for numerous cells producing at least small hail, with larger severe hail certainly possible.
333 PM EDT Thu Oct 24 2024 High pressure builds across the area tonight into Friday.
1239 PM CDT Thu Oct 24 2024 - Temperatures will be warmer than normal for the rest of the week, with highs toward the end of the weekend 20 to 25 degrees warmer than normal. A low pressure system and an associated weak front will move west to east across the Plains today. Temperatures will be slightly cooler on Friday behind the cold front, topping out in the 50s for highs, but remain about 5 to 10 degrees above average for late October. Friday evening, we are in northwesterly flow aloft with a ridge moving in from the west.
(Tonight) Tranquil conditions across the Tennessee Valley region will continue with high pressure in control of our sensible weather. Eventually, temperatures will fall back into the low to mid 50s in most locations by early Friday morning.
At the moment, an upper level trough is positioned across the Southern Canadian Prairies and Northern Plains. Afternoon highs today will generally stay within the low to upper 50s, with the warmest areas in the southern Red River Valley and west-central Minnesota. However, precipitation should be out of the area by the time temperatures dip below freezing, limiting the concern for any snowfall. As the aforementioned trough begins to move out of the region, a very broad upper level ridge is forecast to begin building into the Northern Plains, resulting in a warming trend with relatively dry weather.
1122 AM CDT Thu Oct 24 2024 - Look for elevated fire weather conditions this afternoon immediately ahead of a late afternoon early evening cold front, bringing more gusty winds prior to sunset.

Temperatures along the Island Chain are in the mid 80s with dew points in the lower to mid 70s. A low to mid level ridge remains in place across the southeastern United States with the center of this ridge across the ARK-LA-TEX region according to CIMSS products. Since Florida is on the southeastern side of this ridge, marine platforms surrounding the Keys are observing mainly northeast breezes of to 10 to 15 knots with Island Chain communities observing 10 to 15 mph.
The ridge axis will weaken, while another high pressure builds north of the area behind a dry frontal boundary that will drift southward into our area overnight.
253 PM CDT Thu Oct 24 2024 Tonight and Friday: mid afternoon surface analysis had a stalled dry cold front just north of our CWA. The cold front will become nearly diffuse this evening so no change of airmass will occur. Otherwise, another night of decent radiational cooling will occur but morning lows will still bottom out slightly warmer than normal. Together these features will help maintain the dry weather and warmer than normal afternoon highs.
A cold front currently moving through northwest Kansas will move quickly southeast this evening and move into Osage County around 03Z-04Z.
