Severe Thunderstorms Possible for Bowling Green Weather

Real-time Bowling Green Weather Radar


Yesterday’s weather

As I wrote in our WxRecap post last night, my forecast didn’t exactly pan out the best. I was right on thunderstorms, and I was exactly right on the temperatures.

Our high was 91°F before the rain yesterday, and I am excited about having my temperature forecast be right on. Storms formed in the afternoon, and dumped rain on most of the region, which is why I feel my forecast wasn’t as adequate as it should have been. Read more about the flooding from yesterday here.

Discussion

I’ve been warning about a stormier pattern since last week!

It has finally hit us! As I alluded to earlier in the post, we have already seen some side effects of that, but today looks as if we will continue on that trek. Moisture across the region this morning is more than abundant, with dewpoints in the 70s and Precipitable water values in the 1.6″-1.8″ range.

With highs looking to get up into the upper 80s and lower 90s by this afternoon, this should yield a fairy unstable environment across the region. This will come in conjunction with a weak shortwave moving eastward into the region this afternoon, and the result will likely be thunderstorms.

Now, we have talked about a severe weather threat over the past few days; however, the overall set up and parameters aren’t very impressive to me. We are very lacking in shear, and this is what organizes thunderstorms. Despite this, I do see the threat for damaging winds and hail with storms that go up, but I don’t think it will be a widespread risk.

The greatest risk is for flash flooding, as Precipitable water values should stay fairly anomalous across the region. Overnight, skies will likely clear out, with lows in the lower 70s.

Tomorrow looks interesting again, as the heat is gonna really crank up.

With the orientation of the surface low, winds will be directed from the west-southwest or the west in general, and this will be the reason we really warm up as much as we do tomorrow. Look for highs in the mid 90s, with plentiful moisture as well.

Yeah, it’ll feel awful out there. There is also a severe weather threat tomorrow evening, as well. Though the SPC only has us in a marginal risk, I do see a severe threat, as there will be better shear heading toward the evening and a good amount of instability still remaining across the southern portion of the state. Combine that with a southward advancing cold front, and you have yourself some storms.

Now, I think the storms will be more isolated than today, but any storm that forms tomorrow evening could be severe. Overnight, skies will clear out, with lows in the upper 60s.

Friday looks awesome. Actually, relative to recently, mega-awesome.

With the cold front moved through the region, we’ll see a much more modified air mass in place across our region. Highs will only be in the mid 80s, and dewpoints look to drop too!

This should yield an awesome day! Overnight, skies will be clear with lows in the mid 60s.


Extended Discussion

The long-range is looking relatively simple across the region.

Both major models are pointing towards a more zonal, flat ridge influencing the weather, with a fairly active northern branch of the jet stream across the northern US, and occasionally moving eastward. We look to be on the northeastern fringe of where the ridge sets up, and so there is a good chance that we see some thunderstorm complexes out of that late this weekend and into next week.
