Looking Ahead For This Week May 16-23 2011

I'll be comparing other forecasts for your enlightenment...

NWS Louisville's 7-day says:
Highs upper 50's to near 60 with shower chances for Mon-Wed; improvement by Thursday, highs near 70; warmer for the Fri-Sun period with some unsettled weather expected with highs in the upper 70's.

Wave3 Weather 7-day says:
Highs upper 50's to low 60's Mon-Wed with shower chances; improving forecast for Thursday, highs low 70's; warmer for Fri-Sun with progressively unsettled weather by the end of the weekend, highs upper 70's to low 80's; pick of the week is Friday, dry with highs in the upper 70's.

Whas11 Weather 7-day says:
Highs upper 50's to low 60's Mon-Wed with shower/drizzle chances; improving by Thursday with low 70's; Highs near 80 for the weekend with scattered storms by Sat-Sun.

Here are a few of my thoughts...
I'm looking at the teleconnectors, PNA and NAO. Both point toward a week of below normal to near normal readings. That means don't be looking for a heat wave anytime soon. Especially for the first part of the week. Pesky Lows will continue to spin down cool air and daily shower/drizzle chances.

While things may improve post midweek, temps will still remain below normal thru Friday (albeit much warmer). Normal highs for this week should range in the 75-77 range.

Sat-Sun looks more normal but unsettled weather expected.

Look for temps to average 12-18 degrees below normal thru Wednesday, about 6-7 degrees below normal on Thursday, and 0-3 degrees below normal for Friday, and near normal for the Sat-Sun period.

For Mon-Wed, highs 57-63
Thursday -  upper 60's to near 70
Friday - near 75
Sat and Sun - 76-78
