After four relatively cool days earlier this week, heat and humidity are again knocking at our door. With dew points back in the 60s and the thermometer heading for near 90, this last weekend of spring will show that summer is anxious to become official! Astronomical summer begins on Tuesday, June 21st, the day of the summer solstice, but this entire month has left little doubt of the season's identity. With every day but one at 80 degrees or higher and even a 102 degree day, June has been a steamy month; the average temperature is a remarkable 6 degrees above normal. And even though it has rained at least a trace on 7 of the last 9 days, the rainfall has been scanty and we are running a half inch deficit at Reagan National.
Look for a slight chance of thunderstorms (20%) today and a somehwat higher chance tomorrow (40%) tomorrow as a stalled front to our north and low pressure will lead to quite warm, humid, and unsettled conditions. Any thunderstorms could produce heavy downpours. A ridge of high pressure is expected to develop early in the week, ushering in even higher temperatures Monday through Thursday; readings in the low 90s are likely. A cold front later in the week could knock down the heat, but only slightly to the upper 80s. Keep your cool and enjoy the weekend!
