Monday was unseasonably warm in Southern California with widespread temperatures in the Los Angeles and San Diego areas in the 90s. But a storm forming in the Gulf of Alaska brings about huge changes by late week.
As the storm drops south it becomes noticeably cooler Wednesday and Thursday and colder Friday. By Friday high temperatures will be as much as 30 degrees lower than Monday.
Along with the change to colder temperatures there is also likely to be a little rain and mountain snow. Precipitation amounts will be light but will just add to the stark change to the weather early in the week. Snow levels by Friday drop to near 5,000 feet. No widespread travel problems are expected however because of the light nature to the snowfall.
Thunderstorms will bring the threat for flooding to eastern Europe while heat continues to build in parts of Russia.
Many areas in the Eastern states will have consistent summerlike heat and a buildup of humidity for the last week of May.
Yet another round of storms is forecast fire up across parts of Texas and the southern Plains into Tuesday night with the risk of severe weather, including flash flooding.
The extended Memorial Day Weekend ended on a wet note across eastern Texas when heavy rains and severe thunderstorms moved in late on Monday.
Parts of the Great Lakes and the Ohio Valley states will take a turn of severe thunderstorms with localized flooding downpours into Tuesday night.
Severe storm- and flood-weary residents of Texas and the southern Plains will soon get a break as a change in the weather pattern develops.
