Northern Michigan centered squarely under upper level ridge of that southern stream, maintaining the dry and seasonably mild conditions. the beginning stages of high level moisture advection well ahead of closed upper level low rotating northeast into the central Plains. This low and its attendant weaker surface reflection will continue to work northeast, cutting across the Northwoods later Sunday. Details: Top-down saturation will continue tonight as upstream low pressure works its way northeast. Scattered to numerous showers expected to continue through Sunday as low pressure works right overhead. with highs on Sunday mostly in the lower and middle 50s. Another short wave then quickly follows for Monday afternoon as a deep area of low pressure tracks by to the north.
108 AM EST Sun Nov 10 2024 Temperatures will start to warm again ahead of a cold front that is due Monday night.
(Today and tonight) With a ridge firmly in place through this evening, coupled with this moist air mass we've been dealing with, we'll once again see cloudy skies and humid conditions. Ridging will prevent rain formation again for most of the region today, with any shower that does manage to pop up remaining brief. Expect daytime highs generally in the low to mid 80s with overnight lows generally in the mid to upper 60s.
SP (This evening through Sunday Night) A dynamic heavy rainfall event is ongoing across north-central Louisiana this afternoon as an axis of deeply rooted gulf moisture along a stalled frontal boundary and lifting warm front, supported by additional moisture availability from TC Rafael in the central GoM, has resulted in a flash flood threat.
233 AM EST Sun Nov 10 2024 High pressure crosses the Northeast today and allows for fair weather and relatively warm temperatures.
1037 PM EST Sat Nov 9 2024 Low pressure tracking through the region will bring rain tonight and continue through Sunday. The area dries out for the first part of the work week as a large area of high pressure builds across the Great Lakes.
High pressure will settle into the Mid-South by Monday, resulting is much drier conditions.
- Dry weather returns tonight and continues through Monday while temperatures rebound to near normal beneath a transitory high pressure ridge.
(Now through Sunday) The upper ridge over the eastern CONUS will shift eastward as a potent deep low pressure system over Nebraska lifts east-northeast across the Upper Midwest and Great Lakes regions. Lows tonight and Sunday night will range in the mid to upper 60s over interior communities and around 70 degrees to the lower 70s along the coast. The high rip current risk will also continue along area beaches through the weekend and into Monday and Monday night.

A warm front extends eastward from a triple point in northwest Arkansas to northwest Alabama, which becomes a wedge front just moving into Cherokee County. At upper-levels Central Alabama remains under moist southwest flow aloft between troughing over the central CONUS and strong subtropical ridging off of the Florida Atlantic coast. The better focus will not come until Sunday night as the cold front approaches from the northwest.
As moisture advection increases with the arrival of the trough Sunday night (PWATs rising to 1. Scattered showers will continue to develop overnight into Monday morning although forcing from the trough will not be extreme given that it will be in a weakening state at that point. Overnight lows will be mostly in the low to mid 70s.
1144 PM CST Sat Nov 9 2024 - Rain chances/light drizzle will slowly taper off into the evening hours as the upper level low across south central Nebraska lifts northeast and away from the region.
at this time strong winds are the main concern As the Low continues to progress northeastward into the Great Lakes region, wrap around precipitation will continue to move eastward as well. Most models have been in good agreement of a slower moving progression of the Low off to the northeast and have trended towards lingering spotty rainfall continuing to wrap around the Low through tonight for areas of north central Nebraska, thus have added pops into the forecast through 1am for areas of north central Nebraska. As the Low continues to proceed northeast that precipitation will move east as well and should see an end of rainfall for all locations an hour or two after midnight.
Meanwhile, lower through upper level ridging is centered roughly over the southeastern United States and is contributing to fairly quiescent weather across the Keys. As a result, all shower activity has been relegated to a slug of localized lower level lift across the warmer Florida Straits. Surface conditions are mild with temperatures in the upper 70s and dew points in the lower 70s. Expect overnight lows to range in the mid to upper 70s with dew points remaining in the lower 70s.
