Weather Summary
Weather Underground midday recap for Wednesday, May 23, 2012.

Unsettled weather formed across the Northwest and Upper Midwest on Wednesday as a trough of low pressure settled over the northwestern quadrant of the nation. Moisture streaming across the region continued to support areas of light to moderate rain showers from the Pacific Northwest through the Northern Rockies with chances of snow in the higher elevations of the Northern Rockies. Meanwhile, a cold front from the West moved across the Upper Midwest, Central Plains, and Central High Plains this afternoon and brought rain and thunderstorms to areas of Minnesota and the Dakotas. The Storm Prediction Center issued a slight risk of severe weather development statement for areas from the Upper Midwest and Central Plains into northeastern Colorado through the afternoon and evening. While the main concerns with these storms were damaging wind gusts and very large hail, a couple of isolated tornadoes were also possible.

In the Southwest, fire weather danger remained high across the Southwest as above normal temperatures, single digit relative humidity levels, and windy weather conditions persisted in many areas.

In the East, a few showers continued across the Northeast and the Mid-Atlantic during the afternoon as a frontal system lingered across the Eastern Seaboard. Meanwhile, heavy rain and strong thunderstorms with gusty winds persisted across the southern tip of Florida. Saturated grounds from the heavy rainfall that occurred yesterday combined with today\'s rainfall resulted in Flood Watches in Miami-Dade County. Additional rainfall accumulations were expected to range from 1 to 2 inches through tonight with locally higher amounts possible in more concentrated bands of rain.

... A major change to colder and unsettled weather through Sunday...

A much cooler air mass will work into the area tonight into much of
Friday. A major storm system may take shape Friday through Saturday
as a large low pressure system strengthens over the Great Basin
leading to the possibility of valley rain and mountain snowfall.

It will remain cool and unsettled in the northern mountains today
and Thursday with periods of light rain at the lowest elevations with
some occasional light snow in the mountains. Expect a cool
day east of The Divide on Thursday with a scattering of showers and
isolated afternoon thunderstorms across most of the area.

By Friday... the potential for a significant storm system may start
to affect areas east of The Divide. Areas of rain may
develop over the northern and central basins with wet snow in the
nearby foothills and mountains... especially from midday on. Some
light to locally moderate snow will continue in Yellowstone National
Park... the absarokas and bighorns. Some heavier snow is possible in
the northwest mountains Friday night and Saturday... especially The
Tetons northward into western Yellowstone Park in areas above 8000 to
8500 feet.

The storm system is then expected to gradually lift northward into
Montana Saturday night and Sunday. Cold Valley rain and mountain
snow will continue across the northern mountains... including
Yellowstone National Park through Saturday. Temperatures will start
to recover on Sunday in the northern mountains but it will still
remain quite unsettled in Yellowstone National Park on Sunday with
light valley rain and higher elevation snow showers.

Memorial Day looks much drier with more seasonable temperatures.

Travellers and those with outdoor plans should monitor the latest
forecasts from the National Weather Service on this expected major
change to colder and unsettled weather. Significant snowfall may
accumulate in the central and northern mountains during this
timeframe. The latest forecast can be found at
