Update: No change for today’s forecast.  Friday is looking cloudier than previously predicted.

Tonight’s models have sunny skies for all of Thursday.  High 53-55. It will be increasingly windy. The NBM ( model blend) has winds only 12 mph with some gusts, but tonight’s high resolution models have winds 20mph with higher gusts.   Clouds move in late at night into Friday morning.

Winds increase late morning into afternoon.
Best time to exercise is all day.


A generally dry period is coming up from today, Wednesday, through Monday.  Temperatures will be cool to seasonable 53-60 (average high is 60º).

Late Thursday into early Friday morning, the retrograde low pressure to our east may cause some light showers.   Also some higher winds.

(Higher winds are not a “wind tunnel effect”, as some the TV weather entertainers call it. Winds are caused by pressure gradients between adjacent systems, higher gradients, higher winds.  A wind tunnel is described here.  Such a thing as a “wind tunnel effect” can best be felt at the corner of 15th and Chestnut Street on a windy day.  I wince every time I hear that term used so incorrectly. )

We are switching from a cyclonic pattern to a large scale upper air “ridge” pattern from the latter part of the weekend into next week.
