APRIL 2013 WEATHER OUTLOOK

Posted: Updated:

With a cool, dry March in the past, what type of weather might April offer us?

Overall, I look for April to be warmer than normal. Longer-range forecast models predict a significant change in the upper-level flow pattern across North America. During March, the Arctic Oscillation was stuck in a strongly negative pattern. This caused repeated outbreaks of cold air into the United States east of the Rockies. In contrast, models are offering the development of significant high pressure aloft, which is usually associated with higher than average temperatures. Weather systems approaching from the west will meet this region of high pressure and slow down. This may lead to more rain than normal.

Cool, wet weather will be in store for part of the first week of April. This system will pass and temperatures will rise. The warming trend will continue for much of the month. I do not foresee any freezing temperatures and there is a chance that our first 90 degree reading may occur either in the latter half of the month. The wettest period may occur near the middle of the month.

Stay tuned... we'll see what actually happens.
