The Central U.S. began April with chilly temperatures on Monday, while wet weather continued in the East and West.

A cold upper trough of low pressure from the North reached southward into the Central and Eastern U.S. and ushered another shot of arctic air into the north-central regions of the nation. This translated into well below average temperatures that seemed more reminiscent of winter than spring.

As cold northwesterly flow spread into the Midwest, light to moderate lake effect snow showers developed downwind of portions of the Great Lakes. A Lake Effect Snow Warning and Winter Weather Advisory continued for areas of northern Michigan through the afternoon in anticipation of 2 to 4 inches of snow and strong northwest winds.

Meanwhile, rain and snow showers developed from Upstate New York through the Central Appalachians as a cold front over the Upper Midwest pushed eastward toward the Atlantic Ocean during the afternoon. South of this cold front, a second cold front became nearly stationary from the Lower Mid-Atlantic through the Deep South.

Rain showers and isolated thunderstorms continued along and ahead of this cold front through the afternoon. Farther south, impulses streaming across the southern Florida Peninsula created a slight risk of severe thunderstorm activity during the late afternoon. While the main concern with these storms were severe hail, tornadoes were not ruled out.

Out West, outside of a residual showers in California, rain and high elevation snow moved into the Great Basin and reached the Central Rockies on Monday as the Pacific storm that impacted the West Coast on Sunday moved inland. Isolated rain showers and thunderstorms began to develop from the northern Texas Panhandle into southern Kansas this afternoon as an associated cold front reached southeastward into northeastern New Mexico and the Texas Panhandle.

Areas of the Southern Plains were at slight risk of severe weather development with severe hail and damaging wind gusts through the afternoon and evening.

MONDAY'S WEATHER EXTREMES:

HIGHEST TEMPERATURE (DEGREES F).........................86 Fort Lauderdale, Fla.

HIGHEST HEAT INDEX (DEGREES F)..........................88 Kendall, Fla.

LOWEST TEMPERATURE (DEGREES F)..........................-2 Hallock, Minn.

LOWEST WIND CHILL (DEGREES F)...........................-39 Wainwright, Alaska

HIGHEST WIND GUST (MPH).................................56 Mt. Washington, N.H.

HIGHEST PRECIPITATION (INCHES)..........................0.92 Columbia, S.C.

ON THIS DATE....... Within a 27-minute timeframe, two large earthquakes shook the Scotch Cap Lighthouse on Unimak Island, AK. The quakes caused a massive tsunami, washing away the lighthouse. What is incredible is that the lighthouse's antenna, which was located over 100 feet above sea level, was washed away.
