DISCUSSION
KEY MESSAGE 1...A cold front is expected to approach the region late this week, bringing more chances for showers and storms. This will last at least into the first part of the weekend.
Another cold front is expected to approach our region late in the week bringing the potential for showers/storms as early as very late day Thursday into Thursday night. Deep layer shear will be fairly strong but the forcing does not look to be terribly strong and could also be centered more north of our area. This could limit the severe weather potential. This is still a few days away though and things could change.
At this point it is likely that the aformentioned front with its associated showers and potential storms is likely to linger into Saturday keeping at least the first part of the weekend on the unsettled side. Precipitation chances diminish by Sunday into early next week.
