The National Weather Service anticipates that after today's rain showers and potential thunderstorms, we're in for a dry spell. "A cold front located over the Ohio River Valley will approach and then move through the forecast area by this evening," the National Service reported. What follows is expected to be a blissfully clear weekend, courtesy of surface high pressure that'll swoop in post-frontal theatrics.
By this afternoon, Baltimore locals should keep an eye on the sky for "a brief lull in shower activity early this afternoon before a broken line of showers and thunderstorms is expected to move through as the front moves through the area," according to the National Weather Service. Even though the potent mix of convection may give rise to strong storms, the threat of severe weather seems to be checkmated by "limited CAPE (around 1000 J/kg) and poor lapse rates (5-6 C/km)." Most residents can expect highs residing in the 80s, with some relief in the highlands where 70s are predicted.
Come nightfall, the crisp sheet of dry air will have settled in, nudging temperatures to dip into the more comfortable 60s, though city dwellers might experience lows in the low 70s. This pattern of placidity in the weather is purported to linger right through Saturday. The National Weather Service introduces the outlook with reassurance of mostly to partly sunny skies expected for Friday and an equally calm Saturday, basking under sunny conditions pared with seasonable temperatures staying faithful to the 80s.
For those concerned with aviation and marine conditions, reduced visibility due to rain showers today is on the cards, and the waters may see brief wind speed spikes enough to warrant Special Marine Warnings. "Prevailing VFR conditions are expected as conditions dry out Friday and Saturday," the NWS adds for the aviation community, predicting no significant weather to worry about on Sunday or Monday. Mariners will be dealing with comparatively calm winds until Sunday night when Small Craft Advisory conditions may crop up again.
Baltimore tide-watchers note: tidal anomalies are in ebb, with spots like Annapolis hovering around the action stage. However, creeping southerly winds come Saturday night could tweak those anomalies upward again, although, at this juncture, there's no threat of tidal flooding.
