The first wave of cold April weather will come to an end this evening, but we'll only see a brief respite before getting another blast of cold air for the weekend. A surface high pressure system that's practically overhead will drift eastward as the day progresses, eventually giving us a light southerly breeze and a high in the mid 40s under mostly sunny skies.

Skies will cloud over and the temperature will start to rise this evening as a low pressure system approaches from the west. Lots of rain is expected from the approaching storm. Look for showers starting Thursday morning with thunderstorms possibly joining in during the afternoon and evening hours. Tomorrow's high should approach 60 degrees.

Leftover rain may linger as the storm departs on Friday morning. In the wake of that storm a deep trough of low pressure will get stuck just to our west for a few days, giving us a chilly weekend. Highs on Saturday and Sunday will only be in the lower to mid 40s and we could see a mix of rain and snow on Saturday morning.

While the unseasonably cool weather continues, let's not forget that we're in the middle of an extraordinary warm period of time. Last month was the fourth warmest March on record, and the ninth straight month of above normal temperatures. Three of those months, September, November and December, were their warmest on record, and this year is off to the fifth warmest start since observations began in 1869.
