Baltimore is set to continue its streak of mild weather today, with an expected increase in cloud coverage and westerly winds as detailed by the National Weather Service Baltimore MD/Washington DC. According to an area forecast discussion, a front moving through the region will bring a bit more cloud but no significant cool-down, with highs predicted to push into the mid to upper 50s and lower 60s.
The forecast also suggests the presence of a weak cool front associated with an upper shortwave trough from the Upper Midwest and Ohio River Valley, which will swing across the area this afternoon. Though moisture will be notably limited, and showers, if any, will be light and mainly to the north, the forecast notes that a passing shower or two cannot be ruled out, mainly north of the I-66/US-50 corridor. For those hoping for sunshine, there's a better shot at that south of I-66/US-50 and east of the Blue Ridge.
The skies will clear this evening, especially east of the Alleghenies. Lows will fall into the low to mid-40s, maintaining the region's outlook of mild weather. Looking further into the week, Wednesday will see brief high pressure and sunny skies before a stronger cold front ushers in rain chances and wind on Thursday. Cooler temperatures will settle in on Friday, following another frontal passage over the weekend.
On the aviation front, VFR conditions are predicted to prevail today despite the uptick in mid and high-level clouds. The National Weather Service Baltimore MD/Washington DC cautions that there is a less than 25 percent chance of precipitation at terminals north of a line from KMRB to KFDK and KMTN. Expect "VFR conditions" to continue with brief high pressure on Wednesday and into the weekend. However, sub-VFR conditions and potential rainfall are on the table for Thursday into Thursday night as the cold front crosses.
The marine outlook appears calm for the most part, with sub-Small Craft Advisory (SCA) westerly winds expected through this evening and a brief period of SCA conditions possible in the northern waters. While SCA conditions are largely predicted ahead of an approaching cold front on Thursday, the remainder of the week leading into the weekend should largely see sub-SCA winds.
