I post about weather, sometimes other stuff.

Several additional tornadoes are likely around the Mobile area today in association with the remnants of Tropical Storm Arthur.

[NWS Weather Prediction Center @NWSWPC]

A High Risk for Excessive Rainfall has been issued for portions of the Central Gulf Coast today. High Risks are not issued lightly & indicate the potential for both widespread & life-threatening flash flooding.

🛑NEVER walk or drive into flood waters. Turn around, don't drown!

Potentially strong tornado ongoing with a supercell crossing into MS, toward Bay St Louis, associated with the remnants of Arthur.

INTENSE Tornado ongoing near Stinesville, Indiana.

[WxAtom @WxAtom]

Getting some more scattered weak tornado producers in Indiana, although could become more intense tornado producers at any time as they organize.

[WxAtom @WxAtom]

INTENSE Tornado ongoing near Effingham, Illinois.

[WxAtom @WxAtom]

Potentially strong tornado heading into Charleston, Illinois.

[WxAtom @WxAtom]

Not tornadic, but a supercell in Illinois is currently producing very large, baseball size hail and destructive wind gusts of 80mph.

[WxAtom @WxAtom]

While the MDT area has been struggling, Tropical Storm Arthur formed this morning along the Gulf Coast and appears to have undergone a center relocation deeper into the Gulf. Max winds ~45-50mph.

[WxAtom @WxAtom]

Been about 2 hours and... not a lot has changed. Still have meandering supercells but overall not a lot of tornado activity. Sounding from Lincoln IL did show stable air as expected; might have to wait until sunset for something to get going.

[WxAtom @WxAtom]

Currently have a couple of supercells in central Illinois that could produce intense tornadoes at any time, but are currently struggling with stable air judging by radar data. This could change.

[WxAtom @WxAtom]

Strong tornado continues into Wisconsin.

[WxAtom @WxAtom]

Strong tornado ongoing in Iowa, approaching Lynxville.

Here are our Key Messages for Wednesday (6/17).

Tropical Storm #Arthur Advisory 5 (10 AM CDT, Wed Jun 17): Tropical Storm Arthur Develops Near the Middle Texas Coast. Life-Threatening Flooding Expected Across Portions of the Southeastern United States. https://t.co/tW4KeGdBFb

[WxAtom @WxAtom]

Things not trending the right way this morning for the risk areas (if you want something to happen).
Surface lows coming in a bit weaker than expected and most models have shoved risk southward, with less instability/potent shear overlap.

[WxAtom @WxAtom]

There is also a Moderate Risk (Level 4/5) of severe weather today in the Midwest, but things have become more complicated since yesterday. A morning round of storms has come in much more robust than expected; even so, a few strong/intense tornadoes may be possible later on.

[WxAtom @WxAtom]

PTC One is currently located on the Gulf Coast and will be bringing a major flooding risk to the southeast U.S over the next few days. Close to a foot of rain could fall near Mobile, AL.
