UPPER AIR -- The 500 mb chart for 00Z Tuesday showed .

TEMPERATURE EXTREMES IN THE LOWER 48 -- The lowest temperature in the lower 48 states on Monday was 17 degrees at Alliance, NE and Monday's highest temperature was 100 degrees at Fort Stockton, TX.

ALASKAN WEATHER -- Some clouds and light precipitation remained along the northern Gulf Coast on Monday morning from a storm system that had dissipated over the state. A strong storm system was moving northward into the Gulf of Alaska on Monday evening. A frontal band of clouds spread across the southeast Panhandle. Farther west, another system was found approaching the western Aleutians, with clouds overspreading the island chain. Elsewhere, temperatures warmed as skies cleared in association with a weak ridge of high pressure that stretched across the Alaskan Peninsula into western Alaska. Unseasonably warm conditions continued across the Arctic coast.

The statewide lowest overnight temperature reported on Monday was 9 degrees below zero at Shishmaref. The highest Alaska temperature as of midafternoon was 54 degrees at Skagway.

HAWAIIAN WEATHER -- A trough of low pressure, with a wind shift, moved across the islands on Monday, as the southern extremity of a cold front associated with a storm system in the North Pacific. Some clouds and light precipitation passed across the state. These were enhanced by the afternoon sea breeze that developed with the absence of strong trade winds. A return to more typical northeast trade winds is expected by Tuesday as a high pressure system is anticipated to move toward a position to the north of Hawaii.

WINTER STORMS --- For a description of the terminology used in the official statements issued by the National Weather Service to inform the public of adverse winter weather conditions, please read the Tuesday optional electronic Supplemental Information.

...1857...Another late season snow and frost occurred over the south. Four inches accumulated in sections of Alabama. (Intellicast)
...1877...The second coastal storm in just three days hit Virginia and the Carolinas. The first storm flattened the sand dunes at Hatteras, and widened the Oregon inlet three quarters of a mile. The second storm produced hurricane force winds along the coast of North Carolina causing more beach erosion and land transformation. (David Ludlum)
...1883...A late season snow fell at Sacramento and Cape Mendocino in California. (Intellicast)
...1955...The town of Axis, AL was deluged with 20.33 inches of rain in 24 hours establishing a state record. (The Weather Channel)
...1985...The high temperature of 86 degrees for this date at Medford, OR was the highest ever so early in the spring season. (Intellicast)
...1986...A major spring storm quickly intensified bringing blizzard conditions to much of the Northern Plains Region. Up to 18 inches of snow was reported in North Dakota, and in South Dakota, winds gusting to 90 mph whipped the snow into drifts fifteen feet high. Livestock losses were in the millions of dollars, and for some areas it was the worst blizzard ever. (Storm Data)
...1987...Thunderstorms in northern Texas produced wind gusts to 98 mph at the Killeen Airport causing a million dollars property damage. Two airplanes were totally destroyed by the high winds, and ten others were damaged. (The National Weather Summary) (Storm Data)
...1988...Low pressure off the Atlantic coast produced high winds across North Carolina, with gusts to 78 mph reported at Waves. The high winds combined with high tides to cause coastal flooding and erosion. About 275 feet of land was eroded from the northern tip of Pea Island. (The National Weather Summary) (Storm Data)
...1989...Thunderstorms in central Florida produced golf ball size hail and a tornado near Lakeland, FL. Fair and mild weather prevailed across most of the rest of the nation. (Storm Data) (The National Weather Summary)
...1990...Thunderstorms developing along a cold front produced severe weather in central Oklahoma and north central Texas. Thunderstorms in Oklahoma produced up to six inches of golf ball size hail along I-40 near El Reno, and produced wind gusts to 75 mph at Okarche. Thunderstorms over north central Texas produced softball size hail northwest of Rotan, and high winds which injured two persons southeast of Itasca. (The National Weather Summary) (Storm Data)
