Water vapor imagery reveals a passing mid level trough moving east across south-central Canada, amid an upper jet extending out of the Pacific Northwest across the southern Canadian Provinces, and generally zonal flow aloft over the Northern Plains. At the surface, yesterday's cold front is stalling to the west and is starting to wash itself out in the absence of appreciable mid- upper forcing aloft. Increasing pressure gradient over North Dakota is being noted as the aforementioned mid trough passes nearby, bringing gusty winds in the Devils Lake basin this afternoon. Upper ridging is forecast to extend into the Northern Plains and Upper Midwest Sunday into Monday helping bring warming trend back to the region, of which are forecast to bring temperatures into the low 80s in the southern Red River Valley where low 80s.

- Dry and cooler weather is expected around mid-week, with highs in the 60s. Lows will fall into the low to mid-50s. Heading into Sunday, a closed upper low will be centered over northeastern Arizona by daybreak, crossing over the Four Corners region in the evening. The low is currently forecasted to lift into south central Nebraska/north central Kansas late Monday afternoon. With the low centered over the area, a boundary moving through and some instability, there is concern a few thunderstorms may become strong to marginally severe in north central Kansas Monday afternoon/evening.
109 AM CDT Sun Oct 20 2024 (Rest of today through Sunday) A spectacular weather day is unfolding across the southeast today as temperatures will be warming into the low 70s with a light southerly breeze. Temperatures tonight will fall into the low 40s for most, so we can expect more fog to develop near sunrise Sunday morning, especially over bodies of water.
A closed low will remain over Arizona this weekend. Slow moving closed low over northern Arizona will continue to spill clouds and light shower activity into Northwest Arizona and moisture wraps around the low, though any amounts overnight will be fairly light, and precip chances should stay limited to points east of the Colorado River. The closed upper level low in Arizona will move north into north central Arizona this evening and provide one last round of light showers to mainly the eastern portions of Mohave County this evening and overnight. The low will begin to eject to the east during the day on Sunday.

Radiational cooling conditions will remain excellent allowing overnight lows to fall into the low to mid 40s. Synoptic situation will show little change today as high pressure north of the area remains in place while the upper level ridge axis remains over the Lower MS Valley. Lows will also be a bit warmer than the past few days, in the mid 40s to low 50s. There will be a trough that shifts into the eastern US mid week. Through the TAF period high pressure will remain in control of the region keeping mostly clear skies in place.
Temperatures are generally in the low to mid 40s with winds in the range of 5-10 mph. The result will be generally quiet weather and warmer temperatures.

555 AM CDT Sun Oct 20 2024 (Today through Monday) An upper level low near the Four Corners and weak surface ridging over our area linger today. The upper level low opens up and moves over the Rockies tonight to the Central Plains on Monday while upper level ridge axis over the Western Gulf of Mexico shifts to southern Texas. Little change in the daily temperature ranges are expected, though the Edwards Plateau will trend warmer due to more sunshine.
(Rest of Today) Large scale upper level ridging has shifted more to the south, now across the Gulf of Mexico, while upper troughing over the 4- Corners region was weakening somewhat. The shifting of the upper ridge was placing this region under a NW flow aloft. However at the surface, high pressure centered over the Tennessee and Ohio Valleys will be the main feature controlling our sensible weather. A satellite view indicated clear skies over and around the area, with the closest clouds over the High Plains creeping east.

At the sfc, high pressure centered over WV/VA will continue to ridge across the forecast area.
227 AM 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. Early this morning, a closed low aloft remains centered over central to northern Arizona. Anomalous ridging will then set in this coming work week, amplified by an upstream Pacific trough.
853 AM EDT Sun Oct 20 2024 (Today through Monday) Strong high pressure will be centered over the central and southern Appalachians the next couple days, and a frontal boundary will remain situated to our south.
30 Previous Discussion: /Through Monday/ A strong mid/upper ridge centered from the Mississippi Valley to western Gulf of Mexico will be the main influencer of the local weather for the next few days. Meanwhile, an upper low currently over New Mexico will eventually lift northeast and ride the northern periphery of the ridge tonight and Monday. This low, however, will do little more than cause light east winds today to veer to the south on Monday. Any precipitation associated with the low will remain well north and west of the region. Temperatures today and Monday will be a few degrees higher than yesterday's readings, with highs generally in the lower to middle 80s.
A trough sliding to the southeast from the north Pacific. This inducing a weak ridge over California.

642 AM CDT Sun Oct 20 2024 (Today) High pressure will become more centered over the Tennessee Valley today, keeping dry conditions in place for the later half of the weekend. Current temperatures range from the low to mid 40s under clear skies. Highs today will be on the warmer side of seasonal norms, rising to the mid to upper 70s with abundant sunshine and light northerly winds.
Today will be a pretty quiet morning to start off with partly cloudy skies and high temperatures 5 to 10 degrees warmer than normal. Otherwise, a cold front will slowly descent on the Oregon coast by the evening hours. The front weakens on Monday and becomes more stationary, although the upper level trough will move through Oregon by Monday afternoon.
There may be a few clouds in the morning, but those should generally clear heading into the afternoon as the weak trough that caused them steadily dissipates through the morning hours. A similar day is then expected Monday as the warm air mass remains overhead and high pressure continues to dominate.
* Gusty winds, cooler weather, and light showers are possible late this week. A few days of mild weather is in store to begin the week as transient high pressure moves overhead.

Overnight lows will be similar to last night, but trended slightly warmer.
Highs have topped out today in the upper 70's to lower 80's, with highs expected to be a degree or two warmer for Monday 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.
Expect temperatures overnight to dip into the mid 50s to lower 60s, and afternoon high temperatures on Monday to climb into the low to mid 80s.
Following this progressive system, broad, flattened ridging is expected to build in across interior NorCal through the middle of the week.
The increased moisture will help keep lows from dropping into the 40s tonight, and could remain in the low 60s in the Twin Cities metro, which may tie or break the record of 62. It will be a few degrees warmer with widespread low to mid 80s. An upper low will approach from the southwest Monday night.
Today will be warm and dry, with scattered high clouds increasing by this evening due to an approaching upper- level trough. Southeasterly winds will push temperatures into the upper 60s in the lower valley, about 8 degrees above average for this time of year. The trough is expected to stay mostly northwest of the forecast area on Monday, so no significant changes are anticipated. Precipitation chances remain low at 20-30%, with the highest likelihood in northern Valley County, Idaho, and Baker County, Oregon, by Monday afternoon.
Light winds and mostly sunny skies can be expected for the next few days as high pressure settles in over the area. Through next Sunday The low pressure system that brought cool and windy conditions over the past few days has moved off to the east, leaving behind clear skies and below normal temperatures for much of the region.
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.

1201 PM CDT Sun Oct 20 2024 (Rest of Today) Large scale upper level ridging has shifted more to the south, now across the Gulf of Mexico, while upper troughing over the 4- Corners region was weakening somewhat. The shifting of the upper ridge was placing this region under a NW flow aloft. However at the surface, high pressure centered over the Tennessee and Ohio Valleys will be the main feature controlling our sensible weather. A satellite view indicated clear skies over and around the area, with the closest clouds over the High Plains creeping east.
Discussion: A strong ridge of high pressure will remain in control for the short term period, providing a clear sky and dry weather.
Cooler more seasonable temps expected for midweek. Expect well above normal temps, breezy/gusty winds, and dry conditions today due to upper level ridge axis working its way across the region.
(Tonight through Monday night) During the short term period a mid-level low over the Four Corners will move east into the Central Plains while a ridge of high pressure will flatten over eastern Texas into the Mississippi Valley. At the surface broad high pressure over the eastern half of the US will continue to drift east with long easterly fetch continuing. Elevated seas along the Lower Texas Coast will continue to support a High Risk of rip currents at the local beaches through at least sunset Monday, with coastal flooding conditions until the late night hours of Monday.
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.
205 PM EDT Sun Oct 20 2024 High pressure remains large and in charge, with sunny days and warmer afternoons into midweek.
(Rest of today and tonight) The pesky closed upper low over the Colorado Plateau is finally beginning to slowly drift northeast, and is expected to move toward the central Plains. Although most of the dynamics with this system will remain northwest and then north in Kansas as this system moves out, there is enough vorticity in the base of the trough moving through northwest Oklahoma late tonight to bring some positive (differential) vorticity advection and associated lift for some shower and storm development.
33 inches on the 12Z OHX sounding and mostly sunny skies, highs are expected to reach the low 70s on the Plateau and mid to upper 70s elsewhere.

1243 PM CDT Sun Oct 20 2024 (Today through Monday) An upper level low near the Four Corners and weak surface ridging over our area linger today. The upper level low opens up and moves over the Rockies tonight to the Central Plains on Monday while upper level ridge axis over the Western Gulf of Mexico shifts to southern Texas. Little change in the daily temperature ranges are expected, though the Edwards Plateau will trend warmer due to more sunshine.
Sustained gradient winds from the broad high pressure system over the eastern United States and the proximity of Hurricane Oscar near the Turks and Caicos Islands will keep near- surface winds elevated to moderate to fresh breezes across the Florida Keys tonight. The continental air mass setting in also supports temperatures along the Keys lingering in the lower 80s at noon with dew points in the upper 60s at Key Largo with lower 70s measured across the rest of the island chain. The high pressure system will weaken over the start of the week.
125 PM MDT Sun Oct 20 2024 - Above normal temperatures return and continue through the week under high pressure.
