Gaithersburg Maryland VP2 backyard report for Saturday, September 1, 2012

Saturday started out September on a very warm note, but with late afternoon clouds and showers/storms in the area that unfortunately missed my station totally. Showers/storms were training down from PA on a few NW/SE narrow lines, and my immediate area was in between these lines. Later, storms developed just to my SE, and ravaged parts of Washington DC and more southern Maryland and parts of southern VA in the evening. Muggy all day, tropical air moving in ahead of the remains of hurricane Isaac. We are not out of the woods by far with the remains, along with a stalled frontal boundary, as the next several days have good chances for showers/storms to develop. Cloudy skies should be the rule through mid-week, with a 60 POP on Sunday and highs in the mid 80s, a 70 POP on Monday with highs in the low 80s, lows around 70 both nights. ON Tuesday, there will be a 60 POP for showers, then a 50 POP on Wednesday, highs in the low 80s and muggy nights with lows of 70. Finally on Thursday we might see some sun under partly cloudy skies but still a 40 POP for showers/storms, with highs in the mid 80s. Thursday night and Friday we should finally dry out totally with sunny/clear skies and high temps in the low 80s and lows in the 60s. Saturday sunny skies and a high around 80 starts off the next weekend on the right foot. No flood watches/warnings out for my area posted so far for my area as yet, but they could be - stay tuned.

Current radar shows a few showers and dying storms in central VA, and offshore off Ocean City MD at this time. More showers and storms can be found in parts of many states to my W and NW, namely PA, WV, OH, IN, KY and IL, some from the remains of Isaac and some from the stalled frontal boundary. The NW/SE alignment of precipitation activity is still set up in OH/PA and WV, but has moved south a bit, so those storms don't look to be moving into my area, at least in the morning hours of Sunday.
