* Flash flood watch Friday morning through evening for entire metro region *
Deep tropical moisture from tropical storm Andrea is streaming northward, and brings the likelihood of heavy rain at times Friday. Lighter rains envelop the region overnight.
Through Tonight: Rain increases in coverage from southeast to northeast this evening, with most areas wet by 7-8 p.m. The rain that falls overnight is generally light to moderate, with about half an inch or so falling by morning. Low temperatures are in the mid-60s with winds from the east around 10 mph.
Tomorrow (Friday): Rain is about certain and it may well be very heavy at times, particularly from mid-to-late morning through early-mid evening. Rainfall totals by evening (including tonight’s rain) should be in the 1-3 inch rain, with locally heavier amounts. Take a moment to clear drain pipes and gutters as needed. Localized flash flooding is a strong possibility, particularly in those areas that typically flood during heavy rain events. High temperatures are in the low-to-mid 70s, with generally light winds…although a few stronger gusts (20-35 mph) are possible in heavy rainbands and possible embedded thunderstorms.
Andrea update: As of 5 p.m., Andrea is making landfall in northern Florida (see wind diagram in right panel in image below). It is spreading a massive plume of moisture up the East Coast (see left panel in image below), where it’s interacting with a frontal system. Flash flood watches (shaded in green in the middle panel in image below) span from Florida to Maine.
