Lake effect snow showers continued over the Great Lakes on Friday, while cold air continued to pour across the eastern states.

A ridge of high pressure built over the Plains and stretched eastward over the Eastern Valleys. This created strong flow from the north, which pushed in cooler air from Canada.

High temperatures across the Eastern Valleys and Central and Southern Appalachians ranged from 15 to 30 degrees below seasonable. The Tennessee Valley saw highs in the mid-30s, while the Mid-Mississippi River Valley saw highs in the mid-20s.

To the north, flow over the lakes kicked up more lake effect snow showers over the downwind shores of Michigan, New York, and into Pennsylvania. Snowfall accumulation ranged from 1 to 3 inches in most areas, with isolated amounts up to 8 inches in some areas.

The Northern Plains and Upper Midwest remained bitterly cold with high temperatures just below zero. Early morning low temperatures dropped into the negative 20s and 30s, with the lowest temperature reported at 34 below zero at Big Fork, Minn.

To the west, a trough of low pressure moved off the Northern Rockies and into the Plains, producing a few scattered snow showers from Montana and Wyoming through the Dakotas. Snowfall totals ranged from 1 to 3 inches in these areas.

FRIDAY'S WEATHER EXTREMES:

HIGHEST TEMPERATURE (DEGREES F).........................79 Falfurrias, Texas

HIGHEST HEAT INDEX (DEGREES F)..........................81 Keahole Point, Hawaii

LOWEST TEMPERATURE (DEGREES F)..........................-34 Park Rapids, Minn.

LOWEST WIND CHILL (DEGREES F)...........................-52 Langdon, N.D.

HIGHEST WIND GUST (MPH).................................102 Mt. Washington, N.H.

HIGHEST PRECIPITATION (INCHES)..........................0.68 Kodiak, Alaska

ON THIS DATE....... The same brutal cold air mass of 1989 that has been discussed here the last couple days continued to freeze the middle portion of the country today in 1989. Tioga, N.D., recorded a wind chill of -90 degrees and the morning low at Russell, Kan., was 12 degrees. This is quite amazing since the high at Russell, Kan., the day before was 84 degrees.
