Monday, 5 Sept 2011 Extended Pow County Forecast

Week 1: Strong High Pressure has achored itself over southern Canada and the northern U.S. This will keep temps in Iowa slightly below normal for the first part of the week. The high will drift slowly eastward and bring temps back to near normal for the end of the week. Expect dry conditions for Pow County - the only chance at any precip at all in the next 7 days may be over next weekend. Reminants from Tropical Storm Lee (in the Gulf of Mexico) will drift slowly northward thru the week and end up in the Ohio Valley. This may bring a very slim shot at some precip in east and southern Iowa next weekend - but with the strong high pressure in place, this seems unlikely.

Week 2: High Pressure will maintain to our north and west. This will force any weather systems to our north and east - keeping us dry. We'll see occasional weak systems move by to north - the first of which should pass thru around the 13th or 14th. This system will be dry and breezy, and once again drop our temps to below normal.

Week 3: Expect a pattern change as strong Low Pressure digs into the Pacific Northwest. This will put the mid-section of the U.S. back into a southern flow - inturn pushing our temps to above normal and increasing our low level moisture. Even with the pattern shift, expect very little precip at this time. Best shot at precip will around the 19th. By then, we will need the rain.



Today thru next Sunday 4th-11th: Breezy Today - Dry all week with seasonal high temps in the Low 70's increasing to the high 70's late week - Expect low temps of high 40's to mid 50's.

Monday thru Friday 12th-16th: Dry - Temps Low 70's dropping to Mid 60's and Breezy by mid week.

Saturday and Sunday 17th/18th: Dry/Breezy - Temps 75-80.

Monday thru Wed 19th-21st: Tshowers/Breezy Monday/Tuesday - Dry/Breezy Wed.



What will the Winter of 2011/12 bring?

Here's my best guess right now.  I'll refine it as time goes on.  It may change - but it won't change alot.......

Pow County will see Seasonal "Average Daily" Temps up thru Dec - then Jan, Feb, and Mar will be 3 Degrees Below Average.


Nov:
Average Snowfall - 2.1"
Forercast - 2.5"

Dec:
Average Snowfall - 6.5"
Forecast - 7.5"

Jan:
Average Snowfall - 8.1"
Forecast - 10"

Feb:
Average Snowfall - 7.2"
Forecast - 8.5"

Mar:
Average Snowfall - 3.8"
Forecast - 4.5"

Our Average Snowfall between November and March is 27.7".  I'm forecasting a Total Snowfall of 33.0" - which is 5.3" Above Normal for the time period.

April:  We'll see an inch or two early April.
