Weather Underground midday recap for Wednesday, April 23, 2014
A low pressure system over the Plains created scattered showers and thunderstorms for the northern Plains and upper Midwest on Wednesday. The system pulled abundant moisture northward from the Gulf of Mexico, and produced a warm front that stretched eastward into the Upper Mississippi River Valley. Scattered showers and thunderstorms developed in these areas with rainfall totals ranging around a half of an inch. There was a slight chance of severe thunderstorm development across the central and northern Plains, but severe storms have not yet developed.
Further west behind this low pressure system, another trough of low pressure moved over the Pacific Northwest and into the Intermountain West. Moisture from the Pacific Ocean accompanied this system, which allowed for scattered showers to develop across Oregon, Washington, Idaho, and western Montana. Cooler air associated with this system allowed for snow showers to develop at higher elevations. Snow levels dropped to 3,500 feet across Oregon and Washington Wednesday afternoon. Heaviest rainfall with this system was reported at Astoria, Oregon with a midday total of 0.96 inches of rain.
Elsewhere, periods of heavy rainfall persisted across the far Northeastern states as a low pressure system slowly pushed eastward and off the East Coast. This allowed for rain to persist for Maine, Connecticut, and Rhode Island, with rainfall totals around a half of an inch. Heaviest rain for the region was reported at Taunton, Massachusetts with a midday total of 0.88 inches of rain.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 16 degrees at Stanley, Idaho to a midday high of 95 degrees at Dryden, Texas
