(EXTRACTED FROM FXUS65 KBOU 191040)
(For the 12Z TAFS through 12Z Thursday morning)
Issued at 340 AM MST Wed Feb 19 2020
Timing of the stratus and its height will be a little tricky this
morning. There's no distinct surge but we should see stratus
spread back into the Denver area airports 12Z-16Z as Denver
Cyclone develops and northerly winds advect the stratus in.
Heights may vary between 1000 and about 3000 feet, but little
risk of fog given relatively high T/Td spreads. Could see a couple
flurries develop once the stratus moves in, but most of the light
snow should hold off until upslope deepens behind a cold front
toward mid day. That will also increase north/northeast winds with
gusts to around 20 knots. Light snow expected to become more
widespread by 22Z-00Z and then continue til about 06Z. Total
accumulations are expected to be around 1-2 inches since moisture
is rather limited, with the higher amounts toward KBJC and KAPA.
Clearing expected 09Z-13Z as winds turn light southerly.
