Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Today: Considerable cloudiness early, then more sunshine. Breezy and chilly. High 37.
Tonight: Variable cloudiness with a few snow showers. Low 29.
Tuesday: Morning flurries, then clouds and sun. High 39.
Tuesday Night: Clear and chilly with a low near 28.
Wednesday: Clouds and sun. Milder with a high near 44.
Thursday: Mostly sunny. High near 50.
The extended outlook calls for clouds and sun on Friday with a low in the mid 30s and a high in the mid 50s. Mostly cloudy on Saturday with a low around 40 and a high around 60. Rain showers on Sunday with a low in the low 40s and a high in the low to mid 60s.
High pressure will build over the Middle Atlantic states today. This will result in more sunshine throughout the day, but with cold air pouring over the region we will only record temperatures a few degrees higher than our morning lows. Highs should reach the mid to upper 30s. A gusty wind at times will make it feel a bit colder. Meanwhile, a cold front will sweep across the region tonight. This "clipper" system will bring a few snow showers to Baltimore and Annapolis, with a light dusting possible in some areas. These types of systems are typically moisture-starved and very rarely produce measurable snow east of the mountains. Snow flurries may linger through the early morning hours on Tuesday before giving way to a mostly sunny sky. Tuesday's temperatures will be a few degrees warmer than today, with afternoon readings hovering around the 40-degree mark. The rest of the week will feature a steady rise in the mercury with 40s on Wednesday, low 50s on Thursday, and above 60 on Saturday and Sunday. Unfortunately, warmth is usually accompanied by clouds and rain this time of year. As a cold front approaches the bay from the west on Saturday and Sunday, clouds and precipitation will be on the table. The long-range outlook calls for a return to more seasonable temperatures next week, but no outbreaks of arctic air. Snow chances are minimal through the 25th.
