Sunday’s Temperature Outlook

From the National Weather Service:

Valid 7AM Sunday Apr 28 2024 – 7AM Tue Apr 30 2024

• More rounds of excessive rainfall and severe weather are expected to push eastward into the Lower Mississippi Valley Sunday and Monday

• Warmer than average temperatures spreads from Midwest into Mid-Atlantic today while well below average temperatures shift from the Four Corners and Rockies into the Northern Plains

More active and unsettled weather is forecast to continue across the mid-section of the country through the remainder of the weekend into Monday.

Multiple disturbances embedded within a slow-moving upper-level trough responsible for the active weather are currently developing another low pressure system over the Central Plains. Today, the main area of thunderstorms will push farther eastward toward the Mid and Lower Mississippi Valley with a slightly lower threat of severe weather than Saturday. Meanwhile, the heaviest rains should push farther southeast into the ArkLaTex region as the trailing cold front associated with the low pressure system begins to weaken.

The center of the low is forecast to track northeast across the Central Plains on Sunday, reaching into the upper Midwest on Monday.

Strong to locally severe thunderstorms can be expected to extend northeast across these areas including the Midwest ahead of a warm front to the east of the low pressure center. Meanwhile, the threat of heavy rain will push farther southeast into the Lower to Mid-Mississippi Valley as the cold front pushes eastward.

There’s are Slight Risk (at least 15%) of Excessive Rainfall leading to Flash Flooding over portions of the eastern Southern Plains and Lower Mississippi Valley today and extending into just the Lower Mississippi Valley/central Gulf Coast on Monday. The Storm Prediction Center issued an Enhanced Risk (level 3/5) of Severe Thunderstorms across portions of the eastern Southern Plains and Middle/Lower Mississippi Valley today.

Strong southerly flow behind a high pressure system will bring very warm air northward into the East Coast through the next couple of days with high temperatures climbing well into the 80s to possibly near 90 degrees for the interior Mid-Atlantic.

These temperatures will be in contrast to the cool temperatures expected for the Pacific Northwest by Monday as the next upper-level trough from the Pacific is forecast to push inland. This trough will bring widespread high-elevation snow and lower elevation rain across the Pacific Northwest toward the Northern Rockies on Monday with increasingly windy conditions as a low pressure system begins to develop over the Northern High Plains into southern Canada.
