National Weather Summary for Friday April 24, 2009
NATIONAL WEATHER SUMMARY:
Across the Northeast, breezy and cool conditions were
experienced with clouds and rain across upstate New York and
northern New England. Rain was finally moving out by the end of the
day as low pressure continued to exit to the north of Maine. High
pressure brought mainly sunny skies and pleasant weather from the
Mid Atlantic to the Gulf Coast.
It was very warm across the Southeast with most areas from Louisiana to Georgia seeing afternoon highs in the middle to upper
80s. Severe thunderstorms bubbled up over northern Georgia during
the late afternoon hours and dropped over an inch of rain in the
Atlanta metro area in less than an hour. These storms produced a
lot of hail including hail up to golf ball size at the home of the
Braves, Turner Field.
Over the midsection of the country a large ridge of high
pressure brought very warm temperatures from Texas to Minnesota.
Several record highs were reached across South Dakota and western
Iowa, some including: Sioux City (92); Sioux Falls (91); Huron
(91); Aberdeen (90); Pierre (88). A couple of records were also
broken across the South, one at Little Rock, Arkansas (90) and
another one at Wichita Falls, Texas (94). Cold still lingered
across the northern Great Lakes where Marquette, Mich., broke a
record low of 17.
In the West, a strong cold front dropped across the northern Rockies and brought snow and unseasonably cold weather to much of Montana and northern Idaho. Near blizzard conditions were
experienced over portions of northwest Montana, including Cut Bank
which had a high of only 27, nearly 30 degrees below normal. Winter
storm warning were posted for much of southern Montana and northern Wyoming where 10 inches or more of snow was expected across the mountains and High Plains through today. Dry and warm conditions were felt from California through the four corners region.
