.DISCUSSION...
A few degrees cooler today with a better chance of showers and
thunderstorms developing this afternoon. Rain is more likely to
reach the ground today, with a wetting rain possible if a cell
goes directly over the unit. However, the main hazard with this
activity will still be strong outflow winds gusting 40 to 50 mph
through this evening. Humidity recovery will be improved tonight.
Temperatures drop again on Monday with continued rain chances. The
gusty outflow wind threat will continue.
...Thunderstorms imply strong gusty and erratic winds...
...Haines index is high level haines both day and night...
