Baroclinic Zone Posted July 21, 2011 Author Share Posted July 21, 2011 Southeastern MA and CC/Islands are being spared the worst today it would appear. Still only in the mid 80's at TAN. CC and Islands still in the 70's. Link to comment Share on other sites More sharing options...
snowNH Posted July 21, 2011 Share Posted July 21, 2011 Clouds have really cleared out here.. I wonder if I jump another 3 degrees at 253 pm.. I also wonder if places like FIT and BOS get those clouds that just.came through here Link to comment Share on other sites More sharing options...

Yeah, once those winds veer more westerly, we'll cook. Link to comment Share on other sites More sharing options...
Tropopause_Fold Posted July 21, 2011 Share Posted July 21, 2011 BOS now 97/70 ; HI 106 That's two hours of 104, 106 ...one more and that's Warning criteria. Others are as impressive with 97/70 at FIT... BED's interesting at 94/73, HI of 105...but that's 2 hours also at these other locations. There are more. hmmmm...

They had a similar intrahour heat explosion back in '08 I believe where they reported 102. Link to comment Share on other sites More sharing options...

Typhoon Tip Posted July 21, 2011 Share Posted July 21, 2011 Suspect most site like BOS/ASH/FIT/ ...probably not BED/ but BAF...etc, will touch 100. Going above MOS at this hour it would seem. Lord knows the thermal fields are no limitation - I wonder if the BL/mixing depth is even 850mb yet. Link to comment Share on other sites More sharing options...

CC and Islands still in the 70's. Same with the south coast from east of HVN out through GON and UUU. Looks like the max in those spots will be high-70s east to around 85 west as things are cooling off with a sea breeze now. Link to comment Share on other sites More sharing options...
Typhoon Tip Posted July 21, 2011 Share Posted July 21, 2011 Calm down you doofus - that number by NWS is just as suspect when the charts are higher. Link to comment Share on other sites More sharing options...
weathafella Posted July 21, 2011 Share Posted July 21, 2011 MAV was 7F too low at BOS on the 6 hour prog. MET 3F too low. MET has 100 at BOS tomorrow and I suspect we go to 103. Link to comment Share on other sites More sharing options...

MET has 100 at BOS tomorrow and I suspect we go to 103. yeah MAV was not good for this event. given we gain another 2 to 3C at 850 tomorrow and should have a good launching pad, cresting 100F is reasonable if nothing gets in the way cloud wise etc. Link to comment Share on other sites More sharing options...

snowman21 Posted July 21, 2011 Share Posted July 21, 2011 Yeah I just noticed that at NWS ... Most charts that put these on a matrix have 106 for that combination. Interesting. Using the NWS heat index equation, 97F and 41% RH yields a heat index of 103.5F which has a stated accuracy of +/- 1.5F or something in that neighborhood. The charts could be old. I think the NWS has made a few adjustments over the years to the original Steadman equations that perhaps some charts are based on.

weathafella Posted July 21, 2011 Share Posted July 21, 2011 BOS down to 96......breakoff cloud right at obs time may have dropped it but wonder if we'll resume now that we're cleared or it hit 98-99 in between. Link to comment Share on other sites More sharing options...

Mr. Windcredible! Posted July 21, 2011 Share Posted July 21, 2011 hmmm...i've got 102...will have to dig some more. that would be pretty amazing though. you could be right...I just browsed real quick through their daily extremes on the NWS page, could've missed it if it was 102. Either way...doesn't look like they're gonna break it, down to 98 at 3pm as winds dropped a bit and turned more NW. May of touched 101 between the hours, but that looks like it'll about do it for them. Link to comment Share on other sites More sharing options...
