Issued: Monday, May 10, 2010 Covering: May 12 –May 19

Iwasn’t exactly wrong on the second half of last week’s forecast, but I wasn’t exactly right either. The main storm track did develop to our south, but a pesky little upper low decided to break off from this main storm track and meander over our region during the first part of this week. This brought a mixture of sun and clouds, some showers and cool temperatures.

Well, there is good news ahead for those who want to see a return to above-average conditions. It looks like a fairly strong ridge of high pressure will build over our region during the second half of this week. Under the high we should see a return of sunny skies – and with the clear skies, we should see temperatures warm into the low to mid-20s by the weekend. Overnight lows also look like they will remain mild during this period.

These mild conditions look as if they will continue into the first half of next week before the models start to have trouble. After Monday the models tend to be all over the place with the forecast.

One model run continues with forecasting really mild conditions, then in the next run the models switch to wet and cooler conditions. I guess time will be our only answer. Personally, I think that the warm side will win out, but whatever does happen I think it will set the tone for the summer weather to come.

Usual temperature range for this period: Highs: 13 to 24 C. Lows: 0 to 10 C.
