The nation’s weather

Weather Underground midday recap for Saturday, April 20, 2013.

Showers and thunderstorms ended for the East Coast early on Saturday, while more precipitation moved into the Northern and Central Plains. A low pressure system now over eastern Canada continued to pull a strong cold front eastward, which moved off the East Coast and into the Atlantic Ocean early on Saturday. This brought an end to severe showers and thunderstorms across the Eastern Seaboard. The system produced a few tornadoes in the Southeast with multiple reports of damaging wind gusts over 60 mph from Georgia through New York State into the early hours of Saturday. The tail end of this system lingered over Florida where it produced more showers and thunderstorms throughout the day. Rainfall totals reached over an inch by mid-day on Saturday, but hail and strong winds were not yet reported. Behind this system, cool air from Canada continued to pour across the Northern and Eastern states. High temperatures ranged 5 to 20 degrees below normal for many areas, with highs in the mid-50s to mid-60s for the Eastern Valleys. Meanwhile, the flooding that resulted from this cold front remains an issue for the Lower Ohio River and the Mid-Mississippi River. Some areas have seen historic flooding levels, specifically Illinois was hit the hardest.

Meanwhile out West, another winter storm moved over the Northern Rockies on Saturday and pushed moisture into the Northern and Central Plains. This allowed for rain and snow showers to spread from Idaho and Montana, through Colorado, and into the Plains. Cooler temperatures in the Dakotas allowed for mainly snow showers to develop, while rain showers moved across Nebraska and Iowa.

Temperatures in the Lower 48 states Saturday have ranged from a morning low of -9 degrees at Crane Lake, Minn. to a midday high of 91 degrees at Marathon, Fla.
