Baltimore residents can expect a brief respite from precipitation today, thanks to weak high pressure hovering above, providing a mix of sun, clouds, and calmer winds by this afternoon. While today’s winds are set to gradually calm down, leading to chillier overnight conditions with temperatures dipping into the 20s, the National Weather Service in Baltimore, MD/Washington DC forecasts a turn as a low-pressure system rolls in on Friday, threatening to disrupt the start of the weekend with light rain and snow. Their area forecast discussion states, "Dry conditions are expected through tonight."
As we approach Friday, prepare to brace for a chance of a rain & snow mix, possibly affecting the morning commute, with temperatures hovering in the 30s to 40s, causing a transition from snow to rain in areas outside the mountains. By Friday evening, snow again joins Baltimore’s weather conversation as temperatures dip below freezing. Areas located within the Alleghenies are anticipated to accumulate 2-4 inches, with the possibility of measurable snow extending to NE Maryland. Yet, due to a good bit of model discrepancy, the exact snow totals remain uncertain as we head east of the mountains.
The wintry mix should give way to clearer skies over the weekend as the high-pressure system strengthens its grip leading into early next week. This shift signals a return to drier conditions and colder nights, especially in higher elevations, where temperatures could fall to the teens. The forecast indicates that Sunday to Wednesday will consist of mostly dry conditions, apart from some possible snow showers hitting the Alleghenies by Monday night. Looking ahead to the Christmas holiday, there is a lot of uncertainty, but signs point towards a potential rain/snow mix Tuesday into Wednesday.
For Baltimore aviators, expect VFR conditions today as the weather permits clear visibility with northwesterly winds gradually increasing up to 20 knots. However, plan for potential flight restrictions on Friday, as the weather system introduces precipitation complications. The weekend should bring gusts ranging between 20 and 30 knots, primarily on Saturday, with VFR conditions resuming early next week. Mariners aren't spared from the atmospheric mood swings, with Small Craft Advisories holding sway until this afternoon due to gusty winds expected to ease up thereafter. The weekend forecast advises a strong chance of another round of advisories as winds potentially ramp up again.
