220 PM EDT Sun Oct 20 2024 Dry high pressure persists through the forecast period. Max temps Monday will be a couple of degrees warmer than today. with some areas possibly reaching the 80 mark across the lowest elevations of the Piedmont. Lows will drop off to normal levels each morning with readings ranging from the low to upper 40s across the forecast area. At KCLT and elsewhere: The influence of dry high pressure is expected to result in continued VFR/mostly SKC conditions at the TAF sites through the period.
This is due to a strong high pressure sitting to our north bringing drier and windy conditions to the area. Temperatures will stay consistent day to day with lows in the mid to upper 60's each morning and highs in the low to mid 80's for the next 7 days.
Absolutely nothing new to note, as upper-level ridging holds on strong. Highs tomorrow will range in the low to mid-80s, with highs tonight ranging in the upper-40s to low-50s.
324 PM EDT Sun Oct 20 2024 Dry high pressure will prevail through late week. Sprawling high pressure centered over the Tennessee Valley into the Central Appalachians will maintain its influence on the region tonight.

318 PM CDT Sun Oct 20 2024 Today through tomorrow: The near term period is expected to remain warmer and dry as an upper ridging pattern persists over the southeast region. 5 inches as dry, continental air lingers over the Lower Miss Valley. By tomorrow, a very similar pattern will prevail with highs in the lower 80s.
103 PM CDT Sun Oct 20 2024 Dry and mild weather will continue over the Midsouth through midweek, under an upper level high pressure ridge. This ridge will move out on by midweek, allowing the passage of a weak cold front. Temperatures will moderate to near normal behind this cold front, with continued dry conditions for the latter half of the week.
A powerful low pressure system is lumbering its way over the Four Corners Region this afternoon and will likely produce flash flooding and severe weather across much of eastern New Mexico this evening and tonight. This low is expected to become a deep, open trough and start progressing eastward late tonight into Monday morning.
129 PM EDT Sun Oct 20 2024 High pressure will continue across the area through midweek.
Heading east into the I-35 and Highway 77 corridors, less cloud cover and drier air will allow lows to drop into the lower to mid 50s. Highs should manage to top out in the 80s, except for some upper 70s over the higher terrain of northern Edwards and Val Verde counties. Southerly winds in the low-levels begin to increase Monday night leading to overnight lows in the 60s for most of the region.
A cut-off low centered over Northern Arizona that brought cooler conditions and some light precipitation over the past week is beginning to decay and lift to the northeast. Heights will continue to increase over California as a weak ridge builds in over the region.

Low temperatures tonight should fall into the upper 40s and low 50s for our GA and AL counties, while temperatures generally span the low to mid 50s in FL counties. Tomorrow, highs will generally be in the low 80s and be accompanied with mostly sunny skies.
Drier conditions filter into the area as high pressure shifts westward, bringing an end to any precipitation changes by late tonight through the rest of the short term period.
201 PM MDT Sun Oct 20 2024 Expect decreasing winds tonight, while a Pacific cold front approaches Montana from the west. The cold front will move across Montana on Monday, resulting in snow in the mountains along the Rocky Mountain Front, and light rain showers over the Plains.
(This afternoon through Monday night) Upper low remains over the Four Corners today before beginning to lift northward this evening. As the low begins to lift north tonight, the best environment for storms shifts north and out of Eddy and Lea counties. Heights rise as the trough pulls out into the Plains tomorrow and that brings highs back above average in the 80s for most.
(This evening through Monday) The upper low is beginning to make its northeastward trek to the Four Corners before moving eastward across Colorado tomorrow. This activity will slowly build southward this afternoon and begin slowly pushing eastward late tonight as the upper low pushes eastward.

Additionally, the upper low over northern Arizona will continue to throw some clouds westward into southeast Nevada and northwest Arizona.
Subsidence from high pressure has successfully kept skies mostly clear with temps warming from the low 40s this morning to the low 70s by noon. Temps will be slightly warmer than previous nights dipping down to the mid 40s. Despite the slightly warmer temps, conditions will still be favorable for patchy fog formation through the early morning hours.
- Ahead of the rain Monday, some locations may experience very high fire danger once again with breezy conditions and highs in the lower 80s. The closed upper low that is spinning across the 4 corners region will slowly move toward our area and bring the first chance of meaningful rain in the past 30 days.
Expect highs to top out today in the upper 70's to lower 80's, with highs perhaps a degree or two warmer for Monday with in the lower 80's for most locations. Tonight is another chilly night dipping into the lower to middle 40's over the interior and upper 40's to lower 50's nearer the coast. Expect similar temps tomorrow night, perhaps a degree or two warmer than the night before across the forecast area.

Cooler more seasonable temps expected for midweek. Issued 325 PM CDT Sun Oct 20 2024 Tonight through Monday night: The upper-level ridge axis will slide across southern WI overnight and result in the continuation of clear and quiet conditions. Meanwhile an upper-level trough over the central Plains will gradually creep eastward toward the mid-Mississippi River Valley on Monday. The main difference from today will be the slightly lighter winds due to the high pressure over the Southeast breaking down and relaxing the pressure gradient.
- Cold front arrives Monday, with widespread rain across north- central Idaho and northwest Montana. A cold front is still on track to move through the region Monday as early as 5-6am in NW MT.
Early afternoon satellite imagery shows high pressure remaining in control with mostly clear skies, light winds, and seasonably warm temperatures across ERN Idaho to finish out the weekend. A weak, dry cold front will build in late tonight into Monday and bring with an increase in cloud cover and uptick in winds, peaking Monday afternoon in that 15-25 mph range with gusts to 25-40 mph.

Tomorrow, highs will generally be in the low 80s and be accompanied with mostly sunny skies.
A low pressure system will begin to exit the area Sunday night into Monday, leading to a warming and drying trend that will span across the upcoming week. Persistent, stubborn upper low was located over extreme SE Utah early Sunday afternoon. Farther southeast across southeast Utah, sufficient surface heating has increased lapse rates thanks to cooler air aloft closer to the center of the low to support the development of isolated thunderstorms.
540 PM CDT Sun Oct 20 2024 (This evening through Monday Night) With an upper level low over the Four Corners region, a rather amplified ridge aloft remains in place over the Southern Plains with 500mb heights above 592 dam. Fortunately, 850mb temperatures are only in the 14-17Â°C range, so we'll only see daytime temperatures top out in the low to mid 80s. On Monday, the previously mentioned upper level low will drift eastward through the Central Plains and flatten out the ridging aloft. With the main center of the upper level high still nearby in the northwestern Gulf though, we'll only see 500mb heights fall to 588-590 dam.
Expect decreasing winds tonight, while a Pacific cold front approaches Montana from the west. The cold front will move across Montana on Monday, resulting in snow in the mountains along the Rocky Mountain Front, and light rain showers over the Plains.

851 PM EDT Sun Oct 20 2024 High pressure and dry conditions will continue across the CWA overnight. Subsidence from the upper level ridge and copious dry air in the mid and upper level will be the main factors producing the clear skies.
1057 PM EDT Sun Oct 20 2024 Dry high pressure will prevail through late week. Tonight: Aloft, the local area will remain along the eastern fringes of a ridge extending from the Gulf of Mexico to the mid Mississippi River/Ohio River Valley. At the sfc, a large area of high pressure centered across eastern Kentucky/Tennessee and the Central Appalachians will remain the primary weather contributor across the Southeast United States, keeping all areas dry under clear skies. A few locations could reach the low 40s well inland and north of Lake Moultrie. Deep layered ridging will persist to the west, as a deep upper level low develops well off the North Carolina coast.
High clouds continue to stream across the northern half of the FA, or basically along and north of the highway 200 corridor.
(Rest of tonight) Dry north-northwest flow aloft of 15-25 knots will persist across the TN Valley overnight, as our region will remain located to the east of an amplified 500-mb ridge extending from the northwestern Gulf of Mexico into the Mid-MS Valley.

814 PM EDT Sun Oct 20 2024 High pressure will continue across the area through midweek.
217 PM MST Sun Oct 20 2024 Temperatures remain a few degrees below normal today as a low pressure system exits the region, then a strong warming trend is expected to start the work week. The upper pattern this afternoon is mainly defined by an upper low centered over northwest Arizona/southeast Utah. This feature will unfortunately be replaced by a ridge of high pressure building into the Desert Southwest this week.
Breezy and gusty conditions will remain this afternoon as Florida continues to be sandwiched between a high pressure ridge over the eastern US and a stalled frontal boundary over the northern Caribbean. Thus, have maintained a general PoP 20-30 percent this afternoon across the area, with the highest PoP along and inland from the Volusia County coastline. Seasonable temperatures today, with afternoon highs in the low to mid 80s under partly to mostly cloudy skies. The Coastal Flood Advisory has been allowed to expire this afternoon behind this morning's highest of the high tide cycles.
/NEW/ Update: Quiet weather will prevail into the workweek with above normal temperatures as high pressure remains in control. A persistent upper low over the Four Corners region will finally eject into the Central Plains on Monday. After highs in the lower 80s today, we'll see overnight lows fall into the low/mid 50s tonight. Monday night will be notably warmer as low level moisture continues to increase.
The presence of a healthy dose warmer and much drier based at 800 does preclude deeper convection.
Ridging across the region will keep conditions dry.
Cooler, more seasonable temps expected for mid week. Issued 901 PM CDT Sun Oct 20 2024 Upper ridging will continue over the region through Monday as the upper low over CO moves into the central Great Plains. Gehring Issued 325 PM CDT Sun Oct 20 2024 Tonight through Monday night: The upper-level ridge axis will slide across southern WI overnight and result in the continuation of clear and quiet conditions. Meanwhile an upper-level trough over the central Plains will gradually creep eastward toward the mid-Mississippi River Valley on Monday. The main difference from today will be the slightly lighter winds due to the high pressure over the Southeast breaking down and relaxing the pressure gradient.
A stacked low pressure system, located over the Rockies this morning, should move eastward through the central Plains today and tonight. This area of low pressure should cause southerly flow to increase and help low clouds to break up by mid to late morning. As a result of the warm southerly flow high temperatures this afternoon should be in the low to mid 80s, which is a few degrees warmer than yesterday. Another round of low stratus appears likely tonight with lows around 60 with persistent southerly flow in the low levels.
(This evening through Monday night) The Panhandles are seeing a quiet and slightly warmer afternoon as satellite shows the closed H500 low slowly lifting northeast over the Four Corners. Lift from the low will continue to generate scattered showers and storms overnight, mainly across the northern half of the CWA, with less coverage further south and east of the I-40 and HWY 60 corridors. Lighter winds and clearing skies Monday night will allow for noticeably cooler overnight lows in the 40s by Tuesday morning.
129 AM EDT Mon Oct 21 2024 High pressure remains in charge, with sunny days and warmer afternoons into midweek.
(Now through Tuesday night) The upper ridge extending from the western Gulf of Mexico to the lower Great Lakes will continue to breakdown through noon Tuesday as the upper cut-off low over the Western High Plains ejects toward the east-northeast while developing into an open wave. This trough will continue to move quickly to the east, while a second upper trough dives southeastward from south central Canada to the Upper Midwest. A very dry airmass will continue through today, with afternoon relative humidity values again dropping into the low to mid 20s, generally along and north of I-10. Highs Tuesday will be about 2 to 3 degrees warmer across the board. Lows Monday night should be in the low to mid 50s inland, with upper 50s to mid 60s closer to the coast.
High pressure in the southeast CONUS continues to dominate our sensible weather pattern as it promotes fresh to strong northeasterly breezes. This results in a thankfully boring forecast monitoring for the next high pressure to build across the Eastern Seaboard by this weekend starting the cycle of freshening northeasterlies once again. From synopsis, a broad high pressure system over the eastern United States will promote fresh to strong northeast breezes early today. Breezes will gradually slacken through the midweek, in particular over the northern marine zones as the high retreats north. Breezes will freshen once again by this weekend as another high pressure system builds over the Eastern Seaboard.
High pressure will build into northern Arizona over the coming week, bringing warmer temperatures and dry conditions. 79" at Flagstaff Airport!), a warmer and very quiet week is in store for the region. The weekend storm is now centered over Colorado and will continue moving quickly away to the east, leaving our region with building high pressure that will persist all the way through the weekend.
High clouds were spilling northeast into Kansas downstream of the upper low over the Four Corners region. The upper low pushes northeast into southwest Nebraska by late Monday with southerly low-level trajectories shifting farther east over the southern Plains. Temperatures Tuesday will likely be warmer than Monday with westerly winds and plenty of sun.
High pressure will become the dominant weather feature over the area for much of the week, resulting in dry and mild conditions.
1123 PM CDT Sun Oct 20 2024 (This evening through Monday Night) With an upper level low over the Four Corners region, a rather amplified ridge aloft remains in place over the Southern Plains with 500mb heights above 592 dam. Fortunately, 850mb temperatures are only in the 14-17Â°C range, so we'll only see daytime temperatures top out in the low to mid 80s. On Monday, the previously mentioned upper level low will drift eastward through the Central Plains and flatten out the ridging aloft. With the main center of the upper level high still nearby in the northwestern Gulf though, we'll only see 500mb heights fall to 588-590 dam.
Latest water vapor satellite and RAP upper air analysis trends indicate the powerful cut-off low centered over northeastern AZ is beginning to advance northeastward as an associated mid-level jet streak is rounding its eastern periphery.
Weak cold front this morning and much better humidities today. (Today and tonight) The weak cold front moving through the region is evident on satellite with ample high clouds present. At the surface, high temps today a few degrees cooler than yesterday.
204 AM EDT Mon Oct 21 2024 Dominant high pressure will keep dry in place across the eastern US through much of the week.
1215 AM EDT Mon Oct 21 2024 High pressure remains in control through early this week.
1205 AM CDT Mon Oct 21 2024 Today through tomorrow: The near term period is expected to remain warmer and dry as an upper ridging pattern persists over the southeast region. 5 inches as dry, continental air lingers over the Lower Miss Valley. By tomorrow, a very similar pattern will prevail with highs in the lower 80s.
(Today through Tuesday night) As the upper level low over southern Colorado moves northeast into southern Nebraska/northern Kansas today, the Panhandles will be in the right entrance of the upper level jet. Shear will remain decent over the Panhandles today as the southeast surface winds turn to more southwest and westerly aloft today as the upper trough passes by. Tuesday is expected to be a dry day as the upper level low opens up as it crosses the mid Mississippi River Valley.
