- Northwest Flow Regime Continues

Upper troughing across the Great Lakes will persist into next week. Temperatures will run cooler than normal with Frost/Freeze potential or Saturday, Sunday and Monday nights. Clipper type lows will occasionally bring showers in a northwest flow regime.

A shortwave trough moves through tonight with scattered showers into Saturday morning. The pattern repeats for Tuesday into Tuesday night. The Tuesday low should have deeper moisture to work with, but is moving fast enough to limit the chances of excessive rainfall.

VFR conditions continue through Friday night. There could be some shallow ground fog at JXN and AZO between 10 and 12Z if skies are clear and radiational cooling conditions are optimal. This was left out of the forecast because of uncertainty of cloud cover overnight. Winds will be near clam overnight then southwest AOB 10 knots on Friday. There could be some gusts over 20 knots at times this afternoon.

Lowered NBM dew points for today given soundings showing mixing heights rising to 7500 feet. This yields Min RH to around 25 percent this afternoon. Deep mixing will yield winds of 20 knots at the surface as well, so we will have to monitor for RFW criteria being reached this afternoon,
