In the West, stormy weather is returning to areas from the Pacific Northwest to the northern Rockies, while cool, dry conditions prevail elsewhere. Frost advisories are in effect this morning in some valley locations across interior southern California.
On the Plains, local flooding is affecting eastern portions of Texas and Oklahoma, where overnight rainfall totaled 5 inches or more in a few locations. Meanwhile, colder air is overspreading the southern High Plains. Elsewhere, dry weather has returned to Montana, following Monday’s beneficial snowfall.
In the Corn Belt, widespread, record-setting warmth continues for a seventh consecutive day. Today’s high temperatures will exceed 80°F in much of the Ohio Valley. Rain showers are spreading into parts of the southwestern Corn Belt, including western Missouri.
In the South, warm, dry weather continues to promote fieldwork and rapid crop development. Nearly all (97%) of Georgia’s blueberries have bloomed, compared to 24% at this time last year. Meanwhile, heavy showers and thunderstorms are inching across western areas, including western Arkansas and eastern Texas.
Outlook: For the remainder of today, torrential rain will expand from the southeastern Plains into the lower Mississippi Valley. Local flooding will continue in eastern portions of Oklahoma and Texas, while today’s rainfall (locally 4 to 8 inches) could cause flooding to develop in parts of Arkansas and Louisiana. By mid-week, rainfall intensity will begin to diminish, although heavy showers may persist in the central Gulf Coast States. Meanwhile, highly beneficial rain will overspread portions of the central and southern High Plains. Toward week’s end, beneficial showers will reach the middle and southern Atlantic States. Elsewhere, wet weather will continue in the Northwest, while much of the U.S.—excluding the Far West—will continue to experience highly unusual earlyseason warmth. The NWS 6- to 10-day outlook for March 25-29 calls for warmer-than-normal weather nationwide, except for near- to below-normal temperatures in the Pacific Coast States. Meanwhile, near- to above-normal precipitation across the majority of the U.S. will contrast with drier-than-normal conditions in the Southwest and lower portions of the Ohio and Mississippi Valleys.
