|The weather could put a damper on outdoor celebrations and Memorial Day ceremonies this weekend across stretches of the U.S. The culprit will be a stubborn Plains system that will lumber through the Midwest and Southeast, while more storms zap parts of the West. |
A moisture-logged storm system will send rounds of thunderstorms with torrential downpours through the Plains and into the Mississippi Valley Sunday. Places like Dallas, Houston, Tulsa, Okla., Kansas City, Fort Smith, Ark., and Des Moines, Iowa, will have to be on guard for potential flash flooding due to heavy rain.
Not only rain, but severe thunderstorms will also be a factor in the weather Sunday. The greatest threat for damaging wind gusts and potential tornadoes from these storms will exist across central and southern Texas, as they likely develop during the afternoon and continue through the evening.
Morning sunshine could fool Great Basin and Mountain West residents into thinking the remainder of the day will be dry. But instead, garden-variety afternoon showers and storms will bring a few outdoor celebrations inside. The air will be cold enough for wet snowflakes to mix in across the central Rockies.
The West and East Coasts will be the only dry spots Sunday.
Most of the U.S. will be dominated by warm 70s and 80s Sunday afternoon. The cool spots will include the central Rockies where temperatures will struggle to reach the 40s while the remainder of the Mountain West enjoys 50s and 60s. The Northwest Coast and far northern New England will also hover in the 50s and 60s.
Mother Nature will throw a wrench into the works for parts of the Northern Tier and Central U.S., where outdoor ceremonies honoring those who have served our country could be quite damp. Low pressure slowly pin-wheeling into the northern Plains will ensure the Dakotas, Upper Mississippi Valley, and Great Lakes see plenty of rain Monday.
Very muggy weather combined with southerly winds ahead of the same storm system will yield heavy downpours from the Ohio Valley to the Gulf Coast. More rain will sock Texas, as flash flooding concerns expand across the central and eastern part of the state. In addition to the flooding threat, a few thunderstorms will bring the chance for damaging winds and tornadoes.
Rain will be scattered in nature once again Monday afternoon in the Mountain West, while the East and West Coast conclude the holiday weekend with a good deal of sunshine.
The unofficial start to summer will live up to its name Memorial Day Monday. Toasty 80s and 90s will be common across interior California to the Southwest and from the Gulf Coast to the Mid-Atlantic. The rain will keep highs in the 70s through much of the Central U.S. while 50s and 60s spread across the Mountain West and Northwest.
