In the West, temperatures are slowly moderating. Northwestern producers continue to monitor the effects of recent cold weather on fruit tree blooms and other temperature-sensitive crops.

On the Plains, snow lingers across central and western Montana. Meanwhile scattered showers and thunderstorms stretch from the Dakotas to the southern High Plains. Recent and ongoing precipitation is slowing fieldwork but benefiting pastures and winter wheat.

In the Corn Belt, showers are spreading into the middle Missouri Valley. Elsewhere in the Midwest, dry and unusually warm weather continues to favor fieldwork, including early-season corn planting.

In the South, showers linger southern Texas. Elsewhere, mild, dry weather is ideal for fieldwork, although recently-planted summer crops will need rain soon to promote germination and development.

Outlook: A cool, dry air mass will push southward down the East Coast, with freeze warnings in effect this morning across parts of southern New England and the northern Mid-Atlantic, where early-April warmth promoted an unusually early bloom for some fruit trees. Meanwhile, a storm over southern Canada will produce rain and snow across northern portions of the Rockies and Plains. A trailing cold front will trigger showers across the Corn Belt, with moisture from this system reaching the Northeast and Mid-Atlantic by week’s end. Locally heavy showers will fall over the southern Plains where an influx of Gulf moisture will interact with a stalled frontal boundary. Mostly dry weather will return to the western U.S., although a weak disturbance will generate light rain and mountain snow in the Pacific Northwest. The NWS 6- to 10-day outlook for April 19-23 calls for drier-than-normal conditions in the northeastern quarter of the nation, while near- to above-normal precipitation prevails elsewhere. Above-normal temperatures over the Corn Belt and northern Plains will contrast with colder-than-normal weather from California into the Gulf Coast States.
