Lows will be mainly in a near-50-to-mid-50s zone, but some upper 40s seem possible in the usual “cold” spots. Tomorrow (Tuesday): By all appearances, this will be another winner when it comes to local weather. Conditions will be spectacular as skies remain mostly sunny and highs reach the low to mid-70s. Flirting with 40s: In at least parts of the area, we could see readings tickle the upper 40s tonight. Up at Baltimore-Washington International Marshall Airport, the average first 40s low is Sept. 19.
