The high temperature for the day reached the upper 70s (a bit cooler than the low 80s as forecasted yesterday), with mid 50s in the early AM, dew points were in the mid 50s to mid 60s. Now at 0346 we have clear skies with temperatures in the upper 60s with dew points in the mid 60s. The Monday minimum temperature from the VP2 in the shelter on the ground below my balcony (56.1°) was recorded at 0659 while the maximum temperature (79.1°) was recorded at 1319. Dew point temps rose a bit today, ranging from 55° up to 67°. Relative humidity values were about the same as yesterday’s (97% – 53%).

Remember now you can get the ground-based VP2 data on Weatherlink. You can access the data through http://www.weatherlink.com/user/walrusman444

We now have clear skies with temperatures in the upper 60s at 0346 Tuesday. Tuesday should be warmer with highs in the mid 80s and lows in the mid 60s with partly cloudy skies and a 60 POP for showers/storms later in the day. On Wednesday cooler temps with partly cloudy skies and highs in the mid 60s, lows in the mid 50s with a 70 POP for rain. Thursday and Friday should return sunny skies to the forecast with only a few scattered clouds at times, highs in the low 70s and lows in the mid 50s.

On Weatherbug at 0346 the radar is showing a wide line of FROPA showers and storms running ENE to WSW, cutting through the NW half of PA and western NY state at the present time. Movement appears to be ESE and should reach our immediate area sometime during the day on Tuesday. Major hurricane Irma is still well out in the Atlantic, a day or less from the Antilles, and tracking towards the Virgin Islands, Puerto Rico and Cuba over the next few days. Models are generating tracks running all over the place, NHC forecasts should be consulted frequently to see what is transpiring in relation to our effects, if any, there will be in our region.

    1. Thanks Jeff. I am trying to get back to the main webpage from where I am at now, which is in wordpress. I also signed in to Jetpack, and I think I messed it up.
