All Activity

1.10" of rain yesterday. And just a little haze today from smoke. Looking forward, smoke cast looks rough again for some.

Some pretty nasty supercell and sig tor numbers for western CT and points west on the 12z 3K Nammy. Soundings for HFD, BDL, and BDR. I'm still fairly skeptical of high end stuff here but I think it's an active day.

Not much smoke here yet A heavy trace of rain this morning

Yup starting to get bad here

The severe threat isn’t unitil mid afternoon. The only model thus far that has handled the convection ongoing reasonably well is the HRRR. All the ingredients are there but storm coverage will still be scattered. If the warm front gets hung up further South that would shift the main threat more towards Philly but SPC and NWS confidence is high which is why the elevated risk was expanded Northeast.

We have an extended period of below normal temperatures for late July which looks like it will continue through this entire upcoming week. Our warmest and most humid day will be today, but temperatures will be a few degrees cooler than average. Showers and thunderstorms should develop this afternoon and continue till around midnight. Some areas could see over an inch of needed rainfall. The sun returns both tomorrow and Monday with temperatures in the upper 70's to low 80's. Some valley spots may see lows by Monday morning in the comfortable 50's. Shower chances ramp up again by Tuesday and Wednesday before we clear out toward the end of the work week.

Severe threat is legit today. Storms will be dynamicly driven given the cold front. Veering winds could produce a few tornados. Main threat is damaging wind which looks higher end at the moment.

It’s pouring rain in Marysville with some thunder.

Dunno. I assume fail lol. Maybe if the warm front can push through we can partially clear for a few hours?

Wunderground shows that I got .61" The Tempest App says I got .78" Not sure which one to believe, but either way we got a good opening shot.

Significant cloud cover to the North, East and West of DC presently. The area of storms in PA really has a crazy outflow as previously mentioned.

Today is my first day off in almost a month. I've got a Lord of the Rings concert in Baltimore tonight, and we're getting wings at the Dive beforehand. Naturally, we're staring at a busy weather day.

Socked in the clouds here. Smoke visibility has not changed at all in the last 24 hours.

Well the NAM seems like it has it nailed so far.

HRRR has said smoke should improve over the next 2 hours and I am thinking that will help with heat. No problems on moisture outside!! It is thick. Sunshine has been seriously shrouded in fog and smoke here in Loudoun

Smoke is back! Let's go!

Out this morning myself on a hike

Did the models account for this or are we failing as per usual?

Beautiful morning

I remember the 72-73 as I was 9th/10th grade kid and just gotten my drivers permit, I had left school early and needed some gas in the car. when I left that morning it was short sleeve weather. While pumping gas there came about a huge wind gust that blew over metal signs, trash cans, even broke a utility pole nearby as the wires stretched under the stress of the load. Then, probably the coldest air I ever felt so quickly hit me in the face. McCoys service station had a big outdoor thermometer as you went in to pay. One of the men there said the temp had dropped over 30 degrees from where it was just minutes before. Well, I left and headed home, heat on high in the car and just made it home when it began to snow those big size flakes. My dad called and said there was a run on bread and milk at the little mom/pop grocery that my aunt ran. No school for 2 days afterwards. Artic cold set in with highs not going above 32F and lows were single to 0 in the hill country. The rest of winter was good one the best.

Really nice thunder just now

So far in East Allentown this morning by the airport it has been bone dry. However, it poured for a good 20 minutes in Emmaus ( just my south) in the 8:30am timeframe. Not sure if LVIA recorded any measurable precipitation yet today. Radar to the west looks promising though.
