Tropical Weather: Subtropical Storm Beryl (North Atlantic) Tropical Depression Bud (East Pacific) Typhoon Sanvu (Western Pacific)
Weather Summary
Weather Underground Forecast for Saturday, May 26, 2012.

Subtropical Storm Beryl formed late Friday off the Carolina Coast and is expected to move slowly southwestward over the weekend. The storm may maintain tropical storm strength as it approaches the northeast coast of Florida later Sunday night. The storm itself may dump a significant amount of rain on this part of Florida and adjacent areas of Georgia, potentially good news to an area that is currently in an exceptional drought.

The main weather feature over the nation will be a low pressure system moving off the Rockies and into the Plains on Saturday. Flow around this system continues pushing a warm front eastward, over the Plains and through the Midwest. Expect widespread showers and thunderstorms to develop along this frontal boundary, from the Northern and Central Plains through the Great Lakes. Some of these storms will turn severe with strong winds, large hail, and heavy rainfall. Severe thunderstorms are most likely over Minnesota, Wisconsin, and Iowa. By Saturday evening, the tail end of this system will reach the Northeast, bringing lighter and more widespread showers and thunderstorms to the region.

The back side of this broad low pressure system will continue pulling cool air in from Canada. This will allow for rain showers to turn to snow showers at the highest elevations of the Northern Rockies, Intermountain West, and Central Rockies. At the same time, strong and gusty winds will persist for the southern side of this system. In combination with warm and dry conditions, this will maintain high fire danger for the Southwest and Southern Rockies.

* affected area... fire weather zone 146 and eastern fire weather
zone 148.

* Timing... critical fire weather thresholds are expected to be
