Baltimore's weather patterns are showing some dynamic changes over the next few days, as reported by the National Weather Service. High pressure coming in from the west is expected to pave the way for a warm front on Saturday afternoon before a cold front sweeps through by Sunday morning, bringing with it a fresh chance of rainfall. A secondary cold front sweeps through on Monday, leading to cooler temperatures, then high pressure rolls back in for the beginning of next week, the National Weather Service states.
Today, prompted by a dry air mass and previous system movements, some areas have experienced temperatures in the 40s, with other spots dipping into the low/mid 30s. Meanwhile, gusts topping out at around 25 to 30 mph in the afternoon are blowing through the region, reaching even stronger speeds across higher elevations. The NWS report notes that the enhanced level of mixing has held 08Z/3 AM temperatures in the 40s; however, some spots have decoupled as winds have turned light.
On the lookout for the weekend, by Friday, we can expect seasonable temperatures and some additional cloud cover, especially closer to the evening as the warm front approaches. The weather shift on Saturday could bring a few light showers, leaning towards a more humid atmosphere, with dew points climbing back into the 40s to low 50s by nightfall. As for temperatures, the region may see highs return to the low 60s with some pockets potentially heating up to the mid-60s near I-64 and across the Shenandoah Valley.
As Sunday rolls around, the NWS anticipates a deepening low-pressure zone moving across the Ohio Valley to the eastern Great Lakes, pushing a cold front through the area early in the day. This could mean that highs on Sunday may be bullish, and if the faster progression keeps up, temperatures may need to be lowered by 5-10 degrees west of I-95. Post-frontal conditions could offer us just below seasonal norms early next week.
For aviation interests, VFR conditions seem favorable through Friday, and over the weekend, the passing fronts could cause some disruptions. The marine outlook includes Small Craft Advisories in effect today due to gusty westerly winds, which may need to be extended into the evening for the southern waters. Meanwhile, fire weather concerns persist, with low humidities and breezy conditions promoting a risk for fires throughout the area, as fuels continue to dry.
