(Rest of today and tonight) The cold front remains draped across western-north Texas into south- central Oklahoma this morning with isentropic showers overrunning the surface front into southern and central Oklahoma. Once storms move north of the cold front, the severe weather threat will decrease, but large hail and damaging winds will remain possible with the presence of elevated instability in the cooler post-frontal airmass. As the upper trough approaches late tonight, the cold front will begin to push southward. However, continued moist isentropic lift coupled with the forcing from the upper low will give way to continued shower and thunderstorm activity overnight tonight.
- A cold frontal passage this afternoon begins the active pattern this week, with daily chances for lower elevation rain mountain snow. The cold front pushing east across the state later today will continue to bring showers/mountain snow through the overnight hours Sunday. Cooler temperatures settle in behind the front, with temperatures cooling back towards normal for the week. A broad, upper level trough sets up along the Northwest U.
850 PM MDT Sat Apr 19 2025 - A cold frontal passage this afternoon begins the active pattern this week, with daily chances for lower elevation rain mountain snow.

922 PM EDT Sat Apr 19 2025 High pressure and dry conditions will persist overnight. With the canopy of cirrus overhead, temperatures will be about 5 to 7 degrees warmer than last nights values. (This afternoon through Sunday) Subtropical ridging continues to bring well above normal temperatures with highs peaking well into the mid to upper 80s this afternoon. Not much change in the overall pattern will occur through Sunday as the ridge only begins to flatten slightly southeastward in advance of a cold front pushing into the Mississippi Valley. This will bring another day of well above normal temperatures on Sunday, though highs may be a degree or two cooler given a bit more in the way of cloud cover.
Further east, the large surface Bermuda High continues to ridge westward across the Southeast U. Temperatures in the lower to mid 70s, only expected to drop to near 70/lower 70s by daybreak as the southeast winds around 5-10 mph continue across the area.
Lows temperatures overnight will range from the low 60s in the east, to the upper 60s across the Louisiana Parishes. /15/ Tonight through Sunday Night: The region will remain on the western periphery of a ridge aloft centered just off the Florida/Georgia coastline. This, as high pressure at the surface likewise remains wedged into the forecast area from the west. A low pressure system will lift north northeast from the southern plains into the Upper Mississippi River Valley and Great Lakes Region Sunday afternoon into late Sunday night.
741 PM EDT Sat Apr 19 2025 - Cooler and drier through the weekend.
911 PM EDT Sat Apr 19 2025 Showers and thunderstorms will end this evening with an exiting cold front. Generally dry weather returns Sunday as the front moves south, and high pressure briefly builds in. These storms were exiting as a cold front continues to drop southward across the region. Dry weather is then expected through the remainder of the night as high pressure begins to build in from the NW. Lows will be cooler than last night, though still around 10 degrees above average.
747 PM EDT Sat Apr 19 2025 High pressure will dominate the weather pattern for the Mid- Atlantic through the weekend, with a warm southwesterly wind bringing well above average temperatures through Sunday.

Surface analysis places an elongated, slowly weakening, area of high pressure now centered near Bermuda, with a stationary front draped from Texas northeastward to the Great Lakes region. From synopsis, strong easterlies will remain in place through Sunday night, as expansive high pressure continues to dominate the synoptic pattern for the Florida Keys.
Weak high pressure and drier conditions will build in through the rest of the weekend in the wake of a weather disturbance departing the region.
653 PM EDT Sat Apr 19 2025 * A cold front will push southeast across the region through late evening accompanied by showers and scattered thunderstorms, with a few containing strong westerly wind gusts over 60 mph.
Deep mean layer ridging remains anchored off the Southeast U. Deep mean layer ridging off the Southeast United States coastline is expected to sit and meander for the next several days. Temperatures will remain fairly constant with daytime highs in the lower 80s with the potential for some mid 80 degree readings and overnight lows in the mid 70s.
* This period of warmer and dry conditions will extend into the first half of this week with afternoon west breezes. A short wave trough aloft passing over the region this afternoon will encourage more enhanced breezes that will continue into the evening. Further north across northeast CA closer to the OR border, this trough will possess enough forcing and mid-level moisture that brings around a 10-15% chance for some showers forming in more favorable higher elevation areas west of Highway 395. Highs today will reach into the low to mid 70s for valley locations, and 60s around Sierra valleys.

1259 AM CDT Sun Apr 20 2025 (Rest of tonight and Sunday) As an upper level low continued to barrel through the southern Plains, the Tennessee Valley remains in an area of PVA ahead of a deepening trough axis moving eastward into the area as we approach the early part of the week. Dry conditions persist for now due to the Atlantic high slowing down the progression of the aforementioned low pressure system and subsequent cold front. This will allow for relatively warm low temperatures overnight-- remaining in the low to mid 60s. Easter Sunday brings continued dry conditions ahead of the cold front well to our west.
Today and Tonight: A longwave upper-level trough is expected to move out of the Rockies and approach our region for Easter Sunday, becoming more negatively-tilted with time.
High pressure over the upper Great Lakes this morning is the antagonist to rain chances later today. RAP guidance suggest the best moisture pooling is along the Mississippi River, closer to the low tracking north toward Kansas City this afternoon. If there are showers, the afternoon seems to be the better chance as the warm front (forcing) lifts in and dew points eventually creep up. Remnants from what is anticipated to be a line of storms along a cold front moves in after midnight.
