A cold front will then move south into northern IL late Saturday afternoon into Saturday evening.
238 AM EDT Fri Jun 7 2024 High pressure will move in with less humid air for the weekend.
The upper high will move slightly eastward today and become centered over the FA. The one major difference is the upper high that will be directly overhead and may help suppress convection.
For today, warm advection showers and storms look to develop within a warm advection regime by early afternoon as the low level jet increases across central and then eastern Kansas.
1241 AM CDT Fri Jun 7 2024 High pressure continues to influence the Four State this evening as clear skies carry overhead. Lows should end up in the lower 70's and upper 60's by morning, but with dew points a few degrees cooler when compared to last night, fog probs are lower.
- Relatively cool weekend into the start of new work week (highs 60s to low 70s for most) but turning warmer for the latter half. The long range guidance remains steadfast in breaking down the blocking pattern as we move into the middle part of the new week, with broad upper level ridging/zonal flow taking over. How strong the ridge becomes, and where it moves/centers itself is not clear. Pool of instability holds southward of the systems associated sfc warm front.
(Today through Saturday) The cold front this morning is current just across the northern counties of Alabama but will begin to slide south through the night and into Friday afternoon. As we move through the afternoon, high pressure build in and will be in place through Saturday. Highs will be in the upper 80s to low 90s each day, with Saturday being the warmer of the two.
/NEW/ /Today through Saturday Afternoon/ Expect a much anticipated quiet end to the week across North and Central Texas as upper level ridging builds in atop the Southern Plains. While a cut-off low near Baja Mexico swinging up towards the Desert Southwest will shift the upper ridge center a bit eastward on Saturday, North and Central Texas will still be under its influence.
With a low freezing level (7kft to 8kft) and storm tops projected near 10kft to 11kft, a few cell may produce small hail. KEY MESSAGES: - Persistent upper trough maintains an unsettled pattern - Cooler temperatures expected ------------------------------------------------------------------- An upper low will drift across southeastern Canada and the Great Lakes region Friday through Saturday night.
324 AM EDT Fri Jun 7 2024 High pressure will build into the area through tonight, bringing dry but slightly below normal temperatures.
1244 AM CDT Fri Jun 7 2024 (This afternoon through Friday night) The short term synoptic pattern is generally dictated by the dominant upper ridge overhead, set to slowly meander eastward through Texas tomorrow. The main headlines under this pattern will be the continued heat, with high temperatures exceeding the triple digits both today and tomorrow afternoon region-wide except the higher elevations and Heat Advisories are in effect today for most zones along and west of the Pecos River. The low-level thermal ridge remains at a similar location/intensity for tomorrow, albeit maybe a degree C cooler, and as such, more Heat Advisories are likely for tomorrow as well. Aside from the heat, the other focus in the short term is on largely diurnally and orographically driven convection across the higher terrain today and tomorrow.
Dry conditions with low humidity will continue tomorrow as a reinforcing cold front pushes through the Midsouth tonight. Dry weather and seasonal temperatures are expected tonight through early Saturday morning as high pressure remains over the region. A cold front will move through the Mid-South over the weekend bringing showers and thunderstorms along and ahead of the front.
Temperatures along the island chain are hovering in the lower to mid 80s, with sticky dewpoints in the mid to upper 70s, and winds on land mostly from the southwest at 5 to 10 mph. Surface analysis depicts weak high pressure over the central Atlantic, with a front extending from the Mid Atlantic to the Southern Plains, and a weak trough over Florida. Aloft, water vapor imagery shows a trough moving across the NE Gulf of Mexico. Despite the current lack of activity across the area, the nearby trough aloft plus ample available moisture and instability indicate that convection should redevelop across the region sometime during the day. Rain chances should remain above climo tonight and Saturday, as the trough aloft slowly trudges SE across the Florida peninsula, with ample moisture remaining in place.
(Today through Saturday) Key Messages: - Not quite as hot and plenty of sunshine! High pressure will continue building south across the region through the short term with ample sunshine and slightly drier conditions. Another perk of the high pressure is that it will help to clear out the haze that has been sticking around for what feels like an eternity.
245 AM MDT Fri Jun 7 2024 KEY MESSAGES: - A cold front passage this morning will increase PoPs(40%) immediately along the International Border, with a wetting rain possibility (at least a tenth of an inch) remaining low (<15%).
(Today and tonight) High pressure and continued southerly flow will keep hot and dry conditions over much of West Central Texas today. Afternoon high temperatures today are expected to reach into the mid 90s to 102, with overnight lows tonight only falling into the low to mid 70s.
08/DML (Tonight through Saturday night) Building high pressure will create nice and sunny weather for the next 48 hours. Models are in good agreement that this ridge will continue to build over the next few days, with the NAM being the most aggressive and showing heights of 594 this weekend. Other models show a less intense ridge, but they are in good agreement on the general location of the ridge. PoPs this weekend will be on the low side, with the best chance for rain coming with afternoon showers and storms.
Thunderstorms ahead of and associated with an approaching cold front will continue early this morning. The cold front currently positioned just east of I-95 will gradually push eastward this morning and stall near the coast by midday or early afternoon. This will bring a refreshingly cool evening with dew points falling into the upper 50s and lows in the low and mid 60s. H5 ridge is expected to be centered near the central Gulf Coast during saturday with WNWly mid/upper flow from the Mid-MS Valley into the Mid Atlantic region.
Cooler and less humid today as high pressure builds into the area. The high will be centered over our area tonight, and winds will drop to calm.
Expect warm and sunny conditions for Friday and Saturday as temperatures remain in the lower 90s through Saturday. /MJH/ By Friday night into the weekend, deep layer ridging will strengthen as a high pressure sits over the Southern Plains. Mid-level ridging will influence northwesterly flow into the southeast region, promoting the continuance of a dry, continental airmass over the CWA through the weekend. Temperatures are expected to remain in the lower 90s on Saturday and upper 60s to lower 70s overnight.
(Today through Saturday Night) The short term forecast will continue to be a dry quiet one with high pressure as the main weather feature. Ridging aloft will be shifting east (from far W TX) across SE TX and then the northern Gulf coast these next couple of days.

An Excessive Heat Warning remains in effect for the lower elevations through 8 PM today.
1216 AM CDT Fri Jun 7 2024 (This evening through Friday) Not much of a change to the short term forecast this afternoon as the upper level ridge continues to shift slightly eastward into the Texas Panhandle this afternoon. Thunderstorms should clear the FA just after midnight with overnight lows slightly warmer than previous in the mid 60s to lower 70s. As we head into the end of the work week, expect the above seasonal normal temperatures to continue once again as the upper level ridge sets up over the region.
Isolated showers/thunderstorms across the higher terrain through the weekend will primarily impact eastern Arizona.
220 AM EDT Fri Jun 7 2024 High pressure will move in with less humid air for the weekend.
The aforementioned anticyclone centered over the central Plains This morning will shift into the Mississippi valley over the next 24 hours, intensifying the lee troughing over Colorado. A few shower and thunderstorms may (low chances around 20%) develop along the developing warm front from Scott City and Garden city â eastward as the day progresses.
Moisture will gradually build back into the CWA as modest southerly flow returns, with dewpoints potentially in the lower to middle 60s across eastern Kansas and western Missouri by sunset. Further upstream, a thunderstorm complex originating off the Cheyenne Ridge and Palmer Divide will shift into central Kansas.
with highs expected a few more deg warmer by the peak heating of the afternoon. Highs on Fri will be cooler than expected today.
Barnes With deep upper troughing anchored over Ontario and the Great Lakes and upper ridging building over the Desert Southwest, central Illinois will remain locked in a northwesterly flow pattern through the upcoming weekend. Aided by a 40-45kt nocturnal low-level jet oriented northeastward from the Texas panhandle, a cluster of thunderstorms will develop across southeast Nebraska, then track southeastward toward the lower Ohio River Valley.
120 AM EDT Fri Jun 7 2024 A cold front will move across the area today.
19Z water vapor imagery showed an upper trough axis from the great lakes into northern Alberta with a modest upper ridge over the southwestern U. At the surface weak high pressure was nosing into southwest MO with some dry air advecting into northern MO. This high pressure is forecast to remain over the MO and KS state line into Friday morning leading to clear skies and light winds helping lows to fall back into the middle and upper 50s. 12Z models continue to show strong theta-e and moisture advection with the latest runs shifting the nose of the low level jet into northwest MO.
High pressure will continue to build across the West with warm and dry conditions dominating through Saturday.
Water vapor imagery early this morning shows a deep upper trough centered over the Northern Great Lakes Region, with northwest flow positioned over the Midwest states. Gusts between 25 and 35 mph seem reasonable, with the highest probabilities for 30 mph or greater gusts being near/north of I-74.
A ridge of high pressure will bring rain free weather and less humid air to the Mid-South through Saturday morning. Humidity will increase on Saturday as southerly winds on the back side of high pressure return to the Lower Mississippi Valley.

1127 PM MDT Thu Jun 6 2024 Aviation Section Updated Mainly sunny, warm and dry conditions with relatively light winds are expected today before a weak cold front brings a return to near normal temperatures across the Plains. A weak cold front will move through North-central and Central Montana tonight which will cool Friday's high temperatures to seasonal averages for those locations.
High to mid-level clouds begin building into the area Friday morning along a developing warm front pushing in from the west. By mid-day Friday, the warm front will be in eastern Nebraska - draped north to south - and dewpoints will be closer to 50F before they peak near 60 in the afternoon and evening, especially south of the Platte River. In eastern Nebraska, we may be impacted by both the MCS and the chance of supercells earlier in the afternoon and evening especially on the nose of the developing LLJ and near the warm front. The tornado threat will be highest in the vicinity of the eastward moving warm front. Saturday will be cooler with highs mostly in the upper 70s with northwesterly flow of 10-20 mph.
Dry conditions are forecast to continue Friday and Saturday as high pressure builds to the south.
Moist cyclonic flow around the upper low tracking across Georgian Bay maintains a breezy, unsettled almost fall-like forecast today. 850mb thermal trough will be directly overhead at 5 to 6 C, limiting high temps to the upper 60s to around 70, roughly 1 sigma below normal for June 7. This quickly crests overhead by midday, sending a warm front into the area during the afternoon as low-level wind shifts from the southwest. At the same time, the next upper low begins to sink south across Lake Superior with difluent flow ahead of it forming a weak frontal low over the Midwest that moves in during the evening.

Temperatures on Saturday will be cooler than the previous day with highs ranging from the low 70s to mid 80s. Cooler temperatures are expected Saturday night with lows in the lower 50s to lower 60s.
Lower dew point air filtering into the area tomorrow night supports slightly cooler low temperatures Saturday morning, but ECMWF numbers appear to be slightly too cool for most areas.
/CME/ Today and Tonight: In the wake of a cold front passing through the region, dry post- frontal air may be a cause for celebration as we head into the first weekend of summer! High pressure at the surface and building heights aloft as a ridge moves east along the Gulf Coast should keep skies mostly clear. Don't expect too much in the way of "cooler" afternoon temps as the light northerly wind won't be enough to negate the direct June sunshine, but afternoon humidity only in the 30 to 40 percent range will be followed up by overnight lows in the lower to mid 60s.
651 AM CDT Fri Jun 7 2024 (Today and tonight) High pressure and continued southerly flow will keep hot and dry conditions over much of West Central Texas today.
