LWX going with highs around 100 on Saturday for DC and i95 corridor counties in latest zones (issued at 1:35 pm) with upper 90s on Friday and Sunday... as well as lows in lower 80s Friday night and Saturday night and near 80 Sunday night. Below is the zone forecast for DC:

yay MD XD https://www.spc.noaa.gov/products/md/md1501.html

I don't see anywhere across the US outlooked for Saturday (Day 4) on SPC... don't even mention NE at all anyway lol

Looks like IAD/BWI/EZF should all reach 95 next hour... Stafford already reached... MD Science Center/College Park already reached

BWI and IAD are both 94... breaching ConvT... could probably see them hit 97/98 today

Could be a few isolated severe storms as well with damaging wind gusts... we are MRGL outlooked by SPC today

Considering the 11am temp at IAD was 90 with winds from the S... I am pretty sure we breach ConvT with ease

What the hell lol... super backdoored?

I see AKQ and PHL have issued HA's for tomorrow for pretty much all of their zones... wonder if LWX will issue one along the I95 corridor/metro areas tomorrow morning

Updated morning AFD from LWX mentions perhaps a few days over 100 degrees as well

From the morning HWO for the areas along the I95 corridor (metro areas) and into SE MD:

Well that was interesting... poured for about three minutes just now... checked radar, saw nothing... zoomed in and there is a tiny shower right over me that popped up... another one is right over La Plata

From this afternoon's LWX AFD about Friday and Saturday heat and HI:

LWX zones has upper 90s on Friday and Saturday... mentions HX could be near 110 in DC on Saturday... so maybe we see a rare EHW issued later this week?

Pretty nasty CG strike just a minute ago here Torrential rainfall ongoing here

Sun is back out after some torrential rain here... making it more humid

Maybe a small part of it. LWX AFD mentioned the following:

Sunny

00z 3km NAM isn't bad for tomorrow... has some good storms in C MD into Baltimore and into parts of S MD... has a line that looks nice -- yes it skips the DC region for those that are going to meh it... 01z/02z HRRR both have some decent storms over the mountains getting ready to move eastward... 00z HRRR extended was better for those in MD than those in DC/VA

You are def preparing for it when you said "eh it's okay for east of i95"

Already calling another bust I see... figures

So you are IN for tomorrow? Good to hear

Double super impressive (radar is in Twitter link) Yesterday's high-precipitation supercell as seen by NWS radar between 3am and 2pm Monday traversing MD/DC/and northern VA. As shown on previous tweets, the highest rain totals of 3-6" were in a band only about 15 miles wide, but extended in a path more than 100 miles long. https://mobile.twitter.com/NWS_BaltWash/status/1148583287134121984
