After one of the most active severe weather stretches of early spring, the central and eastern United States is catching its breath today. A reinforcing cold airmass has settled in behind the Easter weekend storm system, bringing a sharp reality check to a country that was sweating through record warmth just days ago. But the respite won't last long — the pattern is already reloading, and the second half of this week looks increasingly significant.

The dominant story across the country this morning is the cold. Wind chills in the teens and 20s are stretching from the Northern Plains across the Midwest, Ohio Valley, and into the Northeast — a jarring contrast to the 70s and record warmth that greeted Easter weekend along much of the East Coast just days ago.

Light snow is possible today across parts of the interior Northeast, with 1 to 3 inches possible in some locations through Tuesday as the upper trough pivots through the region. It won't be a significant event, but slick spots are possible on untreated surfaces during the morning commutes.

The SPC is not highlighting any severe weather threat for today or tonight nationally — a rarity after the flurry of activity over the past week. Florida is the one exception, where isolated to scattered thunderstorms are possible across the Peninsula through the afternoon, fueled by a moist and somewhat unstable airmass lingering ahead of a cold front draped across northern Florida.

For most of the country east of the Rockies, today is a reset day. The atmosphere is taking a breath.

While severe weather has dominated headlines, a quieter but serious concern has been developing across the Southeast. Temperature departures of up to 18 degrees above normal were recorded across parts of Georgia and Alabama in recent weeks, and rainfall has been running 10% or less of normal across much of the region. The combination of anomalous warmth and persistent dryness has expanded moderate to severe drought conditions, with D2 severe drought now reaching into Alabama, Florida, and southern Georgia — and being newly introduced into parts of northern Georgia.

With the warmer and drier pattern expected to continue over the region for much of the coming week, these drought conditions are likely to persist or worsen before any meaningful relief arrives.

The quiet doesn't last. By Thursday, an energetic northern stream upper trough is forecast to push a surface system out of the north-central U.S. toward the Northeast, and in its wake, mid-level flow over the south-central U.S. will gradually swing southwesterly. That shift matters — it opens the door for low-level moisture to return to the southern and central Plains.

The SPC is already flagging an isolated severe storm threat for Thursday afternoon and evening near a stalling front in the central Plains, as a strengthening low-level jet provides the lift needed to fire convection. Deep-layer shear remains a question mark at this range, keeping the threat localized rather than widespread. The WPC has also placed a Marginal Excessive Rainfall Risk on Thursday for parts of the Central Plains into the Middle Mississippi Valley, where moisture return combined with forcing from the upper trough could produce locally heavy rainfall.

Friday adds another layer of complexity, as instability develops broadly across the southern Plains. Isolated to scattered thunderstorms will be possible, with a localized severe threat emerging where shear vectors cooperate — though models remain uncertain on the details.

The signal that both WPC forecasters and ensemble guidance are watching most closely is the weekend into early next week. A closed upper trough tracking slowly inland from the eastern Pacific and growing return flow ahead of it across the central U.S. are creating ingredients for what WPC described as a potentially "broad moderate and high risk potential" for excessive rainfall — a phrase forecasters don't use lightly.

The ECMWF ensemble is more aggressive than the GFS on the magnitude and coverage of this threat, but both point to a heavy precipitation focus somewhere in the Plains and Mississippi Valley for the weekend into early next week. The CPC's 6–10 day outlook supports above-normal precipitation across the eastern half of the central U.S. and the Plains through the period.

This is a setup worth watching closely. With soils already saturated from last week's repeated rainfall events across parts of the Midwest and central Plains, the flash flooding threshold is lower than normal — meaning even a moderate rainfall event could produce significant impacts.
