CAPE Posted April 28, 2021 Share Posted April 28, 2021 We do heat, and we do wind.. The stronger synoptic low and cold front will approach the area Thursday night as the initial main trough axis races quickly from the Great Lakes late Thursday and then offshore by Friday morning. impressive height falls will result in a rapid intensification of the surface low as it moves off the New England coast by midday Friday. Southwesterly winds should start to increase overnight Thursday night as the surface low draws near. This will keep temperatures mild as well, with lows around 60 degrees. The strong cold front looks to cross the area around daybreak Friday with temperatures and dewpoints falling in its wake. In the wake of the front, a secondary vorticity lobe (stronger than previously expected) is forecast to dive quickly south across the region. This will be accompanied by a low-level surge in cold air advection as the surface pressure gradient continues to tighten behind the departing and intensifying low. West to northwesterly winds will increase substantially as a result, especially into the evening hours, as mid-level height falls and cold advection will support efficient mixing to the 850-900 mb levels. Models indicate winds speeds in these levels during this time increasing to 40-45+ kts. Expect sustained winds of 20-25 mph with gusts of 30-40 mph by the afternoon hours, with gusts potentially increasing to the 45-50+ mph range during the evening hours. At this point, a Wind Advisory seems probable for at least some if not most of the area, but given the major shift in the forecast, confidence is not particularly high on the details of this strong wind threat at this time. We will continue to monitor this threat. Link to comment Share on other sites More sharing options...

Looks like thick clouds back to Ohio. I'm ok with not having a sunny 90 degree day anyway. Yeah, I was surprised at the heavy cloudiness when I went out at dawn today. Dew point creeping up too. I hope that trend doesn't catch on for a while yet. 61f Link to comment Share on other sites More sharing options...

WxUSAF Posted April 28, 2021 Share Posted April 28, 2021 Wow @Mrs.J! I usually still have an April electric bill because we have to run the heat some, and the solar isn’t enough alone. May is when my bill goes down to zero/near zero. 1 Link to comment Share on other sites More sharing options...
mattie g Posted April 28, 2021 Share Posted April 28, 2021 @Mrs.J and @WxUSAF... How much solar do you get in the winter? You'd have to get some, even with the low sun angle, right? What percentage of your energy use in the winter comes from solar? Link to comment Share on other sites More sharing options...
vastateofmind Posted April 28, 2021 Share Posted April 28, 2021 Currently 90 IMBY, though RH stands at 36%, so doesn't feel too oppressive out there (to me). Link to comment Share on other sites More sharing options...

You'd have to get some, even with the low sun angle, right? What percentage of your energy use in the winter comes from solar? Minimum is like 300-400 kWh in December and January. Ends up being like 15-20% of total power. Our system doesn’t generate enough to run off credits in the darker months. We end up getting about 6-7 months of the year off the panels more or less. Winter is our biggest power usage from heating, way more then A/C in the summer. 1 Link to comment Share on other sites More sharing options...

Yeah, some of the moms in our family are in their 70s to near 80 so figured that would be most comfortable for them. Some coming from NY and some from VA. Should be a nice time regardless.
