KEY MESSAGES

- Next chance for strong thunderstorms are late Monday and Monday night.

..Showers and thunderstorms tonight and Thursday

Many of the model solutions have scattered shower and a few thunderstorms entering our northern counties late this afternoon and into the evening as the shortwave currently over southeastern Saskatchewan digs down. Some of the models such as the NAM and the RAP have a narrow band of instability with the system. The surface based CAPE is only in the 500-1000 J/kg range, but some of the CAMs have MU CAPE a bit above 1000 J/kg. Deep layer shear is around 25 to 30 kts, but HREF probabilities of any strong updrafts are minimal, and model soundings this evening are not very impressive. Could see some lightning as HREF has 30 to 50 percent probabilities with this shortwave, along with brief downpours.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 1156 AM CDT Thu Aug 20 2026

VFR for most this afternoon with some SCT MVFR cumulus hanging around KBJI this morning. These may work off to the east but if not, should remain SCT and not become a ceiling. Winds slowly turning from W to NW today at 10-15kts and gusts occasionally over 20kts. With light winds overnight we could see some fog potential. Confidence in location is low but DVL, BJI and potentially TVF look to be the favored areas. Would think more of a patchy radiation fog that is locally 1/4-1sm if it does develop. Tomorrow winds NW at around 10kts by 18z.
