Storms keep on coming, even with spring in full swing

A cool, windy and rainy day, followed by a couple of cool but sunnier days, followed by two more stormy days, then a string of cool days, followed by probably another storm.

That may sound like a winter forecast, but it actually applies to this strange spring the county finds itself in the middle of.

A cold front is expected to sweep through late Thursday morning through early afternoon, bringing widespread rain from the coast to the mountains. A quarter- to a half-inch of rain is expected in North County and the inland valleys, while the coast and South County should get a tenth to a quarter-inch. The mountains could get as much as an inch, a good soaking for mid-May.

Strong winds are expected with the front's passage. The National Weather Service has issued a wind advisory for the county mountains and desert, where gusts of 60 mph are possible. The advisory is in effect until 11 a.m. Friday. Gusts should be around 20 mph at the coast and inland valleys.

Widely scattered showers could linger into Friday morning, but the day - and Saturday - should be mostly sunny.

Then yet another storm is expected to arrive late Sunday morning and linger into Monday. That storm should bring similar rainfall totals to the region.

After a cool work week next week, with high temperatures in the upper 60s expected at both the coast and inland valleys, forecast models hint at another storm late next week.

"This pattern of storms isn't crazy, but it's a little bit unusual," National Weather Service meteorologist Casey Oswant said. "It's not normal that it's happening this time of year."

San Diego has already had four rainy days in May, which averages 1.4 rainy days during the normally dry month. The 0.40 of an inch of rain measured so far, before the coming series of storms, is more than three times the usual total for the entire month (0.12 of an inch).

Through Tuesday, San Diego had recorded nearly four times as much rain this month as Portland, Ore. (0.11 of an inch), and 2.5 times as much as Seattle (0.16). Both Northwest cities have also averaged higher maximum temperatures this month than San Diego.

San Diego's 12.41 inches of rain since the start of the rainfall season Oct. 1 is 2.4 inches above normal.
