Would you say you were relaxed?
Headwind? Tailwind? Crosswind? 30 mph is huge but the direction matters. If it was mostly a headwind i don't know how you were even still running but my guess is you might have run sub 17? MAYBE. Both your cardiovascular and muscular endurance are limiting factors too. Unless we know how you normally do in ideal or near ideal conditions those are my best guesses.

Probably sub-16:00 in better conditions and with you in much better shape.

Probably means 5 mph crosswinds with the occasional 30 mph gust
19:24
If your 5K PR is 19:11, there's no way in heck you ran 19:25 in 30 mph wind!
But lets say you really did run 19:25 5K and it was in 30mph headwind all the way. Also say you've read this paper (
https://physoc.onlinelibrary.wiley.com/doi/pdf/10.1113/jphysiol.1971.sp009381
). The effective wind speed would be 15.5km/h (4.3m/s) + 30mph (13.4m/s) = 17.7m/s. Looking at figure on page 10, draw a vertical line at 17.7^2 (313.29m2/s2). 15.5km/h is closer to the 4.47m/s curve than the 3.75m/s curve and so I'd estimate the metabolic cost would be around 75 ml/kg/min!
Using the ACSM metabolic running equation on flat ground and calculating for speed given a 75 ml/kg/min oxygen cost, this calculates to 357.5m/min or 21.45km/h. Over 5K this would be sub 14.
Note: I added the speed of the running to the effective wind speed as the results from the paper were done on a treadmill (i.e., where there is zero headwind wind due to running). But if this was "nullified" by setting the incline to 1%, the metabolic cost would be reduced to 70 ml/kg/min. This still would result in a predicted 15 min 5K.
just find out what the other guys that finished beside you usually run.
