This Mother’s Day weekend will unfortunately feature mostly unsettled and cool weather, though no day will be a complete washout. A frontal boundary will just linger in our vicinity during this period, moving north as a warm front, then retreating south as a cold front. This will allow multiple subtle upper level disturbances to move along this boundary, and each of these will bring a chance for rain.

Rest of today – splendid day with sunny skies and just about average high temperatures around 70ºF.

Saturday – chance for rain early between 7-11AM, then a period of mostly cloudy skies until another round of showers with some thunderstorms rolls through in the evening between 8-10PM. Cooler with high temperatures in the mid-60s.

Sunday (Mother’s Day) – chance for showers in the morning, with steadier rain possible through early afternoon. Cool, with northeasterly onshore winds, and high temperatures in the low-60s. Rain chances should diminish later in the day.

Monday – drying out with temperatures in the low-70s and partly sunny skies.

Possible Tropical Storm Impacting the US During Memorial Day?

Consecutive runs of the GFS forecast model continue to suggest that a subtropical/tropical storm could develop in the western Caribbean off the coast of Nicaragua in the next 10 days or so. It’s far too early to be certain of this, but the trend is worth noting. Recent runs suggest that this storm could make landfall on Florida and then travel up the east coast.
