Friday, September 16, 2011 (KDEN)

The beginning of the period will see the Denver Cyclone from today (Thursday) lingering for a few hours before the south-westerly winds kick in for the first part of the day on Friday. This will keep temperatures cool for the overnight, with low temperatures for Friday being in the upper 40's. Light SE winds shifting SW around sunrise.

Friday will see a warm up in temperatures thanks to this south-westerly flow, but PW values remain around 0.6-0.8 for the day per the GFS model. An upper trough will also make its way through the area midday. With the warmer conditions and this remnant moisture, combined with the energy associated with this upper trough passage, we have a decent chance for some late day thundershowers, especially over the Palmer Divide... POP around 20%. Friday's max temps in the mid 70's with light SW winds, shifting SE in the late afternoon.
