Thunderstorms are expected to bring heavy rain and potential significant flash and urban flooding to the Mid-Atlantic on Thursday, especially along the I-95 urban corridor. Dry conditions, gusty winds, and isolated dry thunderstorms will continue to bring a critical fire weather threat to the northwestern Great Basin into the interior Northwest through Thursday.

Overview
Strong to severe storms developed across the forecast area on June 13th, 2017 during the afternoon hours. At our office, we received reports of hail and wind gusts, with mainly minor damage reported from winds. We also have video footage of two gustnadoes that were observed near Milford, IN and Grover Hill, OH. If you saw any hail and/or wind damage, we would appreciate you sending us your report, using the form here.Wind, Gustnadoes, & Hail:
Here are the details on the wind, gustnadoes, and hail from the June 13th, 2017 Severe Weather event.
Gustnadoes
A few "Gustnadoes" were reported to the National Weather Service June 13, 2017. What's the difference between a tornado, landspout, and gustnado? Click here to find out! Read our public information statement here.
Near Milford Indiana
The first gustnado occurred near Milford, IN around 2:15-2:20 pm ET. Radar shows an outflow boundary just south of Milford. Shortly thereafter a shower begins to develop north of the area but not in the location of the reported circulation. The complex interactions caused a brief gustnado, as shown in the photo and video below. Radar data images created using GR2 Analyst.

This video of the Gustnado was taken by Molly Lewis near Milford, IN.
Near Grover Hill, OH
A video was submitted to WANE TV's Hannah Strong showing a gustnado near Grover Hill, OH. Chaise May took this video around 4:15 pm EDT on June 13, 2017. No damage was reported to the National Weather Service as of 9:32 PM EDT 6/13/17 as a result of this gustnado.
Another video was submitted to Matt Leach from ABC21 WPTA of the Gustnado near Grover Hill, OH. Video was by Brian Recker.
Below is the radar data for the Grover Hill Gustnado. You can see some slight rotation just south of the area. VIL shows the potential for hail and heavy rain, NROT shows some rotation.

Straight Line Wind Damage
Straight line winds from thunderstorms led to wind damage across the forecast area. Defiance, OH, South Whitley, IN, and Elida, OH reported several trees and power lines downed. Elida saw a barn roof blown off, and the back wall of a house blown out with roof damage. We did not get any reports of wind gusts greater than 60 mph, but gusts near Elida could have been slightly more than that as the damage was more significant.

Hail
Hail up to 1" in diameter was observed across the forecast area from the storms. Storms were very pulsey, so they often popped up quickly then collapsed-dropping some hail and causing gusty winds (in some cases damaging). Here are the photos people sent to us (thank you!) and some radar images of the storms.

Environment
​Synoptic
A strong upper level ridge and area of surface high pressure kept our area hot and dry for a few days. High temperatures were in the upper 80's and low 90's across the region. A weak upper level disturbance was able to erode the periphery of this ridge just enough to allow for storms to pop on Tuesday afternoon, though overall forcing was weak. Given the lack of upper level support and wind shear, the storms were very pulsey in nature. This means they would develop strong "cores" then quickly collapse.

Mesoscale
Strong to severe thunderstorms crossed parts of Lake Michigan Monday night (12th) into Tuesday morning (13th), which led to an outflow boundary that merged with the normal lake breeze. This boundary moved inland throughout the afternoon. The atmosphere was moist and very unstable, thus storms triggered along the incoming boundary as it moved inland in the early afternoon. Gradually, this boundary interacted with additional outflow from the storms that developed, and produced even more storms. Because the atmosphere was very unstable, stronger updrafts were able to reach above the freezing level and the -20C level aloft, producing hail of up to around 1" in diameter. With limited wind shear, however-the storms quickly collapsed. At times, this produced wind gusts of 30-60 mph.

Moisture
It was pretty humid around the area. Just for some perspective, the precipitable water values of 1.4-1.7 inches were about 125-175% of normal! Storms were somewhat slow moving and produced heavy rain, leading to a few reports of flooding.
