All Activity

I got a quick email reply, but it contains bad news regarding getting QBO updates: “Hi The QBO we have is produced using the NCEP/NCAR Reanalysis which has ended production. We are trying to determine how we will compute this time series. See https://psl.noaa.gov/news/2026/r1datanotice.html Cathy S. Your PSL Data Team”

Look at all this incredible warm summeriness on the extended Euro!

91/56

Gotta be all of that here too.

Most of the hail was around 1" - 1.50". A lot looked fractured like this picture. It was so dense I'd imagine there was a lot of breaking as it fell. We were on the northern edge of the heaviest. Solon/Bentleyville on east through Southern Geauga seemed to get the worst.

The 12z/00z convection-allowing models have a ton of activity in this time frame tomorrow (20z-00z), with these helicity tracks shown. The 12z HRRR shows many strong helicity tracks in Wisconsin.

90F and not proud...

Hanging 84-85. Jumped in the pool to cool off. Didn’t think I’d be in this pool in mid April

87 here. TORCH!

High of 86 so far.

Could be another big day with an expansive Enhanced Risk. Locally, the NAM likes the idea of keeping severe wind gusts going into Michiana late into the evening. Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1241 PM CDT Thu Apr 16 2026 Valid 171200Z - 181200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS EXTENDING FROM WISCONSIN SOUTHWESTWARD INTO OKLAHOMA... ...SUMMARY... Widespread severe thunderstorms are expected from parts of the southern Plains to the Middle and Upper Mississippi Valley vicinity Friday into Friday night. Tornadoes, possibly strong, very large hail, and swaths of damaging winds will be possible. ...Synopsis... An upper trough will move into the central and northern Plains during the day, strengthening through Friday night as it moves into upper MS Valley. Continuous height falls will occur across the entire central to northern Plains region, where mid and upper level temperatures will already be relatively cool. During the afternoon, low pressure will develop across IA and WI, with a cold front extending southwestward into southern KS and northwest OK. A warm front will also lift across IA and into WI during the day, with an influx of mid 60s F dewpoints. Given the cool temperatures aloft, this will create a highly unstable air mass ahead of the cold front. This front will accelerate during the evening as storms become numerous, and should extend roughly from Lower MI into central TX by 12Z Saturday. The combination of steep lapse rates aloft, ample shear, and ample moisture will support corridors of significant severe storms, including all modes of severe. ...From IA into WI and northwest IL... Strong tornado potential is evident Friday afternoon into early evening, especially from IA into southern WI and northwest IL. While convective evolution is a bit uncertain, there is good agreement in a very unstable environment with midlevel lapse rates to 8.5 C/km, along with 200-300 m2/s2 effective SRH ahead of the surface low and near the warm front. While an eventual squall line may take shape late in the day, scattered supercells appear likely after about 19Z ahead of the developing low and as dewpoints rise rapidly. As such, conditional tornado probabilities have been increased further to indicate stronger tornado potential. Cells should eventually consolidate as the front pushed east, with damaging bowing structures expected, possibly as far east as Lake MI. The severe risk is expected to persist as far east as IN and lower MI late evening/overnight as the southerly low-level jet brings moisture northward. Damaging winds appear possible. ...OK/KS/MO... A volatile environment will develop near and ahead of the cold front Friday afternoon, with significant severe hail, wind, and several tornadoes expected. An impressive combination of deep-layer shear/wind fields and steep lapse rates aloft will exist, and while the forcing mechanism will be linear, shear vector orientation and likely rightward-propagation of the stronger supercells will support tornadoes and very large damaging hail initially. All this activity is expected to merge into a linear MCS, with corridors of destructive winds and continued large hail risk expected over much of MO and into northern OK through the evening. ..Jewell.. 04/16/2026

Snow coming obviously.... But seriously, the early morning sky did remind me of the hazy days of August. Different reasons I suppose. On the 2pm obs, the bay breeze is really doing its thing:

Not good

Or in October, when the high school football season is in full swing. Get ready for a lot of mud games

48 years ago, the opposite occurred in Maine. On May 29, 1978, Eastport touched 70 then the onshore breeze and fog dropped the temp to 49 at mid-afternoon. Same time, HUL read 96. Yesterday the sun at least tried soon after lunchtime. No tries today.

88 BDL

Did crack 70 here, car interiors up to 100 or so. not bad.

Yup…gotta be inland this time of year…anything 5-10 miles of the ocean is toast in mid April…unless you have a major off shore flow. Remember when I had my Harley…bunch of buds would say let’s take a-ride down the shore on a hot day like this in April …and I’d be like no way. One time they talked me into it. 88 when we left here in April, 48-50 when we got within 8 miles of the water. Was Like driving into a freezer. Absolutely Horrid.

87 at home. 62 here at the beach in RI.
