Central Florida's Weather Woes: Storms, Drought, and Heat

Central Florida has been experiencing waves of storms at all hours of the day and night due to a huge, stubborn upper low parked over the southeast U.S. This upper low has been generating heating-of-the-day storms by providing more lift to spark storms. Additionally, the main atmosphere railroad that keeps storms moving from west to east is jammed up right now by a huge omega blocking pattern, which may hold into next week, keeping rain and storm chances elevated.

Severe thunderstorms threaten High Plains, Rockies, and Great Basin this weekend.

An Omega block pattern is transitioning to a Rex block pattern over the Great Lakes, which will "trap" an area of disturbed weather over the Rockies, resulting in daily chances for showers and thunderstorms. Severe weather alerts have been issued for millions from Wyoming to Texas, with large amounts of hail and lightning strikes reported. The severe weather threat will continue for several days, with daily thunderstorms forecasted for the Rockies. The Omega block pattern looks to stick around for the foreseeable future.

May brings surprise winter weather with snow and rain.

The "omega block" weather pattern will bring winter-like conditions to the Valley in the first week of May, with a persistent area of low pressure resulting in well-below average temperatures, rain, and even some snow. Temperatures will struggle to reach the mid-40s on Monday, potentially putting the record lowest high temperature of 45°F for May 1 in jeopardy. The high temperatures to start off the month of May will be 20+ degrees below average for this time of year, and there is the potential for records to be broken. Snow is not uncommon in the month of May, with the snowiest day historically occurring on May 9, 1966.
