Weather Underground midday recap for Friday, December 28, 2012.
A trough of low pressure over the Mississippi River Valley created active weather for the Eastern Valleys on Friday. The system to the south pulled abundant moisture in from the Gulf of Mexico, which allowed for showers and thunderstorms to develop from eastern Texas through the Tennessee Valley. Some of these storms turned severe with heavy rainfall and strong winds. Rainfall totals surpassed 2 inches in parts of Louisiana, while wind gusts ranged from 30 to 40 mph. Heaviest rainfall was reported in Oakdale, Louisiana with a mid-day total of 2.43 inches of rain. The northern side of this system remained cooler and allowed for snow and freezing rain showers to spread from Oklahoma through Missouri. This created dangerous roads and travel conditions for the region.
Further North, a trough of low pressure moved from the Upper Midwest and over the Great Lakes. This brought snow showers to the region and allowed for lake effect snow showers to develop along downwind shores of the Great Lakes. Snow showers were reported from Wisconsin through western New York states. Snowfall totals range from 2 to 4 inches in these areas.
Meanwhile out West, a low pressure system dropped southward down the West Coast, and pushed a cold front slightly onshore. This produced scattered rain showers from northern California through British Colombia.
Temperatures in the Lower 48 states Friday have ranged from a morning low of -16 degrees at Pine Ridge, S.D. to a midday high of 82 degrees at Marathon, Fla.
