.WHAT HAS CHANGED... No significant changes with this forecast package.

.KEY MESSAGES... 1) Unsettled weather is expected to return this weekend.

KEY MESSAGE 1...Unsettled weather is expected to return this weekend.

An omega pattern to the jet stream this week, with our region situated within the favorable sector, will break down by the end of the week as a deep closed low over the PACNW bears down upon our region in a weaker state.

Day to day warming through the week, combined with a southerly moist flow late in the week, will lend to building instability by the weekend. This, combined with lift ahead of the shortwave trough will increase confidence for showers and thunderstorms, especially during the peak heating of the day for the weekend.

Given this precipitation is fashioned more for convection than stratiform, there is still expected to be plenty of dry time through the weekend days. Latest ensemble guidance still displays a slight chance for storm activity Friday, with next Saturday and Sunday the greater odds for convection development.

Forecasted PWATs (Precipitable Waters) are expected to reach 1.5 inches or so, which would allow for downpours of rain within any stronger thunderstorms.

High pressure will settle across the eastern Great Lakes region through mid-week with light winds and gentle waves.
