Weather Underground midday recap for Wednesday, April 30, 2014
More heavy rainfall and strong thunderstorms developed across the Southeast on Wednesday, while the Mid-Atlantic states saw severe thunderstorm development. A strong cold front continued moving across the Eastern states and continued pulling abundant moisture northward from the Gulf of Mexico. This allowed for heavy rainfall and flooding to continue across the Southeast, moving into the panhandle of Florida. Rainfall totals surpassed 5 inches in some locations across the Florida panhandle, with up to 9.52 inches of rain reported at Destin, Florida, and 7.14 inches reported at Panama City, Florida. These areas saw rainfall rates over 2 inches per hour, which caused major flood damage to roads, homes, and people. Please remember to stop and turn around when you come to a flooded road as it is always deeper than it looks.
At the same time, the northern side of this cold front stretched northward up the East Coast and also brought heavy rain and flooding to the Northeastern states and New England. There was a slight chance of severe thunderstorm development for parts of the Mid-Atlantic states, as moisture and energy continued to pour in from the south. Severe thunderstorms were expected to develop from South Carolina through Washington D.C., with large hail and strong damaging winds as the main threats, with a couple of tornadoes possible.

Weather Underground Forecast for Wednesday, April 30, 2014
A cold frontal boundary will move slowly eastward over the eastern third of the country on Wednesday, while a ridge of high pressure will linger over the West Coast.
A strong low pressure system will continue to bring active weather to the central and eastern thirds of the country on Wednesday. A cold frontal boundary extending from the central Gulf Coast to the Ohio Valley will interact with a warm, muggy air mass moving northward from the Gulf of Mexico. This interaction will initiate strong to severe thunderstorms across the Southeast and the Mid-Atlantic. These thunderstorms will be capable of producing heavy rain, tornadoes and damaging hail. Heavy rain associated with these storms could lead to flooding from northeast Georgia to southern New England. An area of rain and snow will also develop across the northern Plains, the upper Midwest, the Great Lakes and New England. A separate swath of rain and snow showers will develop across the central and southern Rockies and into the southern Plains.
Meanwhile, a ridge of high pressure is expected to dominate the western third of the country on Wednesday. This system will bring warm, dry conditions to the region, especially over the Desert Southwest. Temperatures are forecast to range between the 80s and 90s across the Southwest, while temperatures will range between the 70s and 80s across the Pacific Northwest.

Weather Underground midday recap for Wednesday, April 23, 2014
A low pressure system over the Plains created scattered showers and thunderstorms for the northern Plains and upper Midwest on Wednesday. The system pulled abundant moisture northward from the Gulf of Mexico, and produced a warm front that stretched eastward into the Upper Mississippi River Valley. Scattered showers and thunderstorms developed in these areas with rainfall totals ranging around a half of an inch. There was a slight chance of severe thunderstorm development across the central and northern Plains, but severe storms have not yet developed.
Further west behind this low pressure system, another trough of low pressure moved over the Pacific Northwest and into the Intermountain West. Moisture from the Pacific Ocean accompanied this system, which allowed for scattered showers to develop across Oregon, Washington, Idaho, and western Montana. Cooler air associated with this system allowed for snow showers to develop at higher elevations. Snow levels dropped to 3,500 feet across Oregon and Washington Wednesday afternoon. Heaviest rainfall with this system was reported at Astoria, Oregon with a midday total of 0.96 inches of rain.
Elsewhere, periods of heavy rainfall persisted across the far Northeastern states as a low pressure system slowly pushed eastward and off the East Coast. This allowed for rain to persist for Maine, Connecticut, and Rhode Island, with rainfall totals around a half of an inch. Heaviest rain for the region was reported at Taunton, Massachusetts with a midday total of 0.88 inches of rain.

Wintery weather will continue across the upper Midwest and Great Lakes region as a winter storm continues moving eastward throughout the day. The low pressure system that moved over the central Plains will continue moving northeastward and over the Great Lakes, moving into eastern Canada. Cold temperatures along the northern side of this system will allow for snow showers to persist for parts of Minnesota, Wisconsin, and Michigan. Winter weather advisories have been issued for these locations as snowfall totals will range from 6 to 10 inches in northern Wisconsin and the upper peninsula of Michigan. Overnight low temperatures will drop into the single digits again in these areas, with daytime highs hovering around freezing. The southern side of this low pressure system will create a cold front that extends across the Midwest into the Plains. This will allow for scattered showers and possibly some thunderstorms to develop across Colorado, moving into the southern and central Plains into the afternoon and evening hours.
Further west, a low pressure system moves into the Pacific Northwest, pushing abundant moisture in from the Pacific Ocean. This will produce moderate rain showers across Oregon, Washington, and Idaho, with snow likely to develop in the mountains.

Weather Underground Forecast for Tuesday, April 01, 2014
A cold frontal boundary will extend from the southern Plains to the western Great Lakes on Tuesday, while a separate cold front will move across the West Coast and the Intermountain West.
A cold front will propagate eastward over the central third of the country on Tuesday. Widespread rain and thunderstorms will develop along the frontal boundary and push across the southern and central Plains, as well as the lower and middle Mississippi Valley. Parts of Texas, Oklahoma, Kansas and Missouri will have a chance of severe thunderstorms. Low pressure along the northern tier of the front will usher moderate to heavy snow showers across the upper Midwest and the western Great Lakes. This system will also move rainy weather over the Ohio Valley and the central Great Lakes.
A separate cold front will trek across the Southwest, the Great Basin and the Intermountain West. The heaviest rain associated with this system will move across California, while heavy snow showers will push across the Sierra Nevadas. Snow accumulations in the Sierra Nevadas are forecast to range between 6 to 12 inches above 7,000 feet, while snow accumulations at 3,000 to 6,500 feet will range between 3 to 6 inches. An onshore flow from the Pacific will also usher precipitation across the Pacific Northwest, as snow showers are expected across the Cascades. This cold front will shift eastward over the Great Basin and the Intermountain West during the afternoon, providing heavy snow showers to portions of the Rockies.
