9/5/2019 11:59 PM 0.00 0.0 0.00 0.0 0.00 Thursday was quite a changeable day as Hurricane Dorian inched northward along the East Coast, with its initial outermost bands of circulation entering our region today. Skies were cloudy most of the day, but with a very thin overcast in the AM and early PM, the sun filtered through the clouds much of the time. High temps held in the 70s all day, as the high temperature for the day was reached at midnight, and then started falling slowly through the 70s most of the day with a few glitches in that pattern – mid-morning brief temps in the upper 60s for the day’s min then a bit of a rebound in the afternoon for a time when a PM max temp of 77.3 degrees was recorded at 1540.

9/6/2019 11:59 PM 0.00 0.0 0.00 0.0 0.00 Finally Friday was the day that Hurricane Dorian paid our area a visit, albeit quite a mild one as the center of circulation remained well south and east of our area. Clouds from the outermost bands of Dorian kept us cool and breezy through mid-afternoon, then as it moved off to the NE skies brightened and the sun warmed us up into the mid 70s by late afternoon. Rain bands only got as far as southern Maryland from what I saw, and stormy conditions in the state were really confined to the Maryland beach area with high surf and stiff NE winds blowing the rain around quite a bit at times. Dorian was mostly a Cat 1 storm on Friday, coming ashore on the North Carolina outer banks area, and back offshore NE of Cape Hatteras. High temps held in the 70s till evening, when temps dropped to the mid 60s for the day’s low by midnight observation time under clear skies.
