89.6f humidity 77% dewpoint 80f feels like 109f currently. I too have not mowed the grass in 4 weeks even after getting 2.00" of rain in 27 hours last week.

Yep, water vapor flow tells all. Our flow is coming right out of the west central Gulf of Mexico right up from Tropical Storm Beryl right to us. Now the Euro showed heavy rain this week from remnants of Beryl looking at the flow it is definitely plausible. The precipitable water right now is off the charts for us at the current time. Water Vapor Map trace the flow right to the Gulf and far southern states. Pennsylvania Water Vapor Satellite Weather Map | AccuWeather

Right now, 88f feels like 109f humidity 80% dewpoint 80f my gauge is in the shade can this be correct? I mean I have never seen heat like this before this early in the morning.

Yep my low was 80 f cam down at 3:48 it was 80f with a dewpoint of 78f

Looks like quite a bit of SSE shear there is not much left almost looks like the system has split in two low level circulation has been taken away from the mid-level circulation.

Now with that said the Euro may also be indicating more favorable conditions for development as well.

The two main factors are how quickly does or will the upper air low in the western bay of Campeche get out of the way and can Beryl slow down and sort of get slung a bit to the WNW or even NW to slow and develop underneath an area of developing area of high pressure as the upper air low vacates west bound. I think in regards if Beryl can get itself together and strike as a Cat 1 to Cat 3 hurricane the odds are like 45% that it will and 55% that it won't so yea 50/50 at this point.

79f DP 74f low last night was 76f. Looks like we have a bit of activity coming in from the west moving due east hoping it stay together to give the garden a drink a bit we shall see. It does appear that it is weakening quite a bit.

Clearly looks like there was definite weakening also due to the proximity to the land mass of Jamaica. Last hour looking at the water vapor map there is a blow up on the southeast side where there was pretty much nothing just a bit ago. It will be interesting to see how Beryl fairs as it moves away from Jamaica. Grand Cayman outside of any shear and or dry air will have zero impact on Beryl.

The uplift on the mountains in the central and western part of Jamaica must be incredible right now. I know the mountains are further from the coast, but this has to have some effect on the overall circulation and structure inflow and outflow from the center to some degree. The flooding in the mountains is very likely really bad to catastrophic currently.

I will say that the center is definitely close enough for the circulation center to be disrupted by the high mountains of Jamaica.

Especially if it is moving as fast as it is right now.

Probably double that at least with upsloping over the mountains of Jamaica with a strong flow around the hurricane the lift will be insane especially if it slows down at all.

I would say looking at the shear ahead and the movement at a brisk 23 mph even at the Category 5 strength that Beryl has been at it will weaken fairly rapidly. Liken it to blowing a candle out. How quickly or slowly will certainly determine the impacts to both Jamica and the very vulnerable Grand Cayman. All interests in Jamica, Grand Cayman, and Play Del Carmen along with both Cozumel and Cancún in Mexico (all these areas big vacation and cruise areas) along with the Western Gulf Coast Mexico up to Louisiana need to monitor the future movements of Beryl.

pretty much done here just missing to my SSW and moving SE I would suspect this is pretty much the front moving on through going to end with 2.05" over past 24 hours perfect!

Dark again moderate rain with thunder 72f humidity 97% dewpoint 71

Partly sunny now thunder overhead and to the east and southeast a few drops of rain still picked up 1.33 during that batch. 0.67" last night plus our 1.33" we have 2.00" on the nose currently 71f humidity 96% dewpoint 70. Looks like a little line in Chester County developing and pushing east southeast. Should be interesting to see how that progresses. No damage or power loss here.

I am still waiting for it to end but skies clearly brightening off to the west and northwest.

Flooding rains booming thunder winds gusting to 40 mph with some pea size hail. Well over an inch of rain for sure totals coming after the storm passes 70f dewpoint 69f down from 86f dewpoint 78f feeling like 103f

Sunny 86 feels like 105 here humidity 89% dew point 78 crazy. I see big, towering white thunderheads due north.

Cloudy here in Media sun looks like it's trying to burn through these low-level clouds though. 81 feels like 88 humidity 97% dewpoint 76f. Total rainfall here so far since last night .70"

picked up 0.62" rain barrel filled. 74f humidity 98% dewpoint 74f. I see fish row down there in Sea Isle has flooding going on pretty serious area of training Thunderstorms. Paul....

Light rain trace so far. 78f humidity 82% radar to the west looking promising for a .35" or more please!!

Here you go Dailylurker: This morning, we wake up to more dry weather complete with very low humidity and low dew points. The new normal around here over the past 20-30 years has been to take a period of abnormally dry and very very quickly replace it with very very wet. Today's 6z GFS hints at this possibility as we head into the first 10 days of July. It is fitting around Southeastern Pennsylvania to end a dry drought like with flooding rains. I am going to put this possibility out there on today, Friday, June 28th. July 7th: GFS Model – MSLP & Precip (Rain/Frozen) for CONUS | Tropical Tidbits July 10th: GFS Model – MSLP & Precip (Rain/Frozen) for CONUS | Tropical Tidbits I think someone said yesterday, next we look for the drought busting tropical system it may not be far off base actually with a stalled boundary. We shall see!
