Dave murray’s latest stl forecast and weather disco…For friday…June 28, 2013.

*** the swing to the northwest flow starts on friday…Looking like a pretty nice day and then almost chilly for the weekend…July chilly…A very weird pattern for july***


Partly sunny and rather nice…Dropping humidity
Winds: northwest 5-15 m.P.H.
High: 88 degrees

Friday night:

Mosrlty clear skies and nice
Winds: northwest 5-15 m.P.H.
Low: 65 degrees.

Saturday and sunday:

A mix of clouds and sun…Cool for july…But watch for a few showers and thunderstorms
Winds: northwest 5-15 m.P.H.
High: 79 degrees.

The cool trend gones into the middle of next week

The weather disco:

A very weird yet impressive weather pattern digs in over the next few days…The big dome of summer retreats back into the southwest and this monster northwest flow develops for the eastern two-thirds of the nation…Anchored by a giant low pressure system over the great lakes…A very non-july weather pattern. Friday looks like a very pretty day for july…Partly sunny skies, mid to upper 80’s as the humidity continues to pull back…Clear and pleasant on friday night. Then over the weekend…The northwest flow is locked in place…A much cooler weather pattern with below average temperatures…Day and night. Now everyone repeat after me…Never trust the northwest flow…Perfect! So we have to watch for thunderstorm clusters that drop from north to south in the flow over the weekend and into next week…Plus with the cool air amss for july…This will tend to keep some clouds around too…Lets think a mix of clouds and sun…Not a wash out weekend…But not pisture perfect either. Where is that sweater.
