Good afternoon, the latest update from the Storm Prediction Center is in and instead of doing the afternoon update, I’m going to combine it all in one large blog post, this may be a bit on the long side, so bear with me. We are going to break down some of the larger cities that’s under each of the categorical risk. The entire state is under the gun for severe storms on Friday, so everyone need to be weather aware tomorrow. The following cities/locales are under the enhanced risk…Evansville, Jasper, Bedford, Madison. The following cites are under the slight risk, Indianapolis, Anderson, Muncie, Bloomington, Terre Haute, Richmond. Finally, these cities are under a marginal risk, South Bend, Fort Wayne, Kokomo, Lafayette, Gary. Now overall for the state, an enhanced risk of severe storms is possible for southwest and south-central Indiana, with a marginal risk for central Indiana, and a marginal risk for northern Indiana.
***Potentially a significant severe weather event is possible, especially in the enhanced risk area*** Showers and thunderstorms will be ongoing Friday morning and we won’t how the morning storms will play in the afternoon/evening severe weather, but right now, conditions are in place for a rather active afternoon/evening. A new round of showers and thunderstorms look to develop during the afternoon hours and move southeast. Initial storms may be supercellular in nature and could produce very large hail (up to and possibly slightly over 2 inches in diameter), damaging winds, and isolated tornadoes, before storms congeal into line and bowing segments, when damaging winds will become the primary threat, but large hail, and isolated tornadoes will also be possible. The severe threat may wind down by the early to mid evening hours, but chances of showers and thunderstorms will remain in the overnight hours. Following graphics is what the FutureCast radar predicts from 1 am to 8 pm Friday. Errors in timing between 1 and 2 hours either way…
We are going to end this blog with potential hazards, beginning with the enhanced risk area. All modes are in play, including the risk of isolated tornadoes, but damaging winds, and large hail, some possibly over 2 inches in diameter will be possible. Within the slight risk area, I also think that all modes of severe weather are possible, with damaging winds and large hail being the primary threat, but isolated tornadoes may also be possible. Finally for the marginal risk area, damaging winds and large hail will be the primary threats, but can not totally rule out a tornado or two.
To end this blog, I will say what I normally would say, there’s a lot of uncertainties in regards to the overall severe weather potential, we have seen where conditions dynamically looked favorable, little or no severe weather occurred. This could very well happen again tomorrow. The keys is again how the morning convection, how fast it can move out of the area, and whether we see strong surface heating, if the sun can remain in check and we are dominated with cloud cover, then the severe threat will be limited, however, areas that end up seeing prolonged sunshine and strong surface heating, then those will be the areas that will most likely see the severe weather. The best you can do is remain weather aware, follow the safety tips below, have a plan of action in the event of warnings, and we will get through tomorrow together, whether severe weather occurs or not. As far as coverage, we will likely begin coverage as the morning storms move into the state, likely during the overnight hours around 1 or 2 am and we will continue until the severe potential is over. Tomorrow will be declared a “Weather Alert Day”. Updates will be available on our Facebook page.
