WEST ROCKVILLE MARYLAND WEATHER UPDATE – THURSDAY JULY 29, 2021 – MY 71ST BIRTHDAY
My birthday Thursday was not as warm as Wednesday but more humid with dew points rising from the upper 60s early into the mid 70s by the early afternoon. We only warmed up to the mid 80s by mid-afternoon. The day was partly to mostly cloudy with late afternoon/early evening light thunderstorms featuring gusty winds at times, a bit of lightning and thunder but only traces of rain. The daily minimum temperature around 70 was reached in the early morning just after sunrise.
The peak winds (26 MPH) were moderately strong in the light thunderstorm action in the early evening, veering slightly to a westerly direction in the early evening convective activity. Barometric pressures were highest in the very early morning while the lowest was at the very end of the day.
Friday should still be warm but gradually less humid and dry, with highs in the mid 80s and lows in the upper 50s. Saturday should be partly cloudy and not as warm with highs in the low 80s and lows in the low 60s. Sunday should have similar temps as Saturday but be partly to mostly cloudy with chances of showers, mostly in the afternoon. Monday should be partly cloudy and a bit warmer with highs in the mid 80s and lows in the low 60s.
