OVERCAST WITH LIGHT PRECIPITATION ON THE LEADING EDGE OF MILDER AIR….
After a bright, but cold day yesterday, today the clouds have
returned, giving us yet another day with very limited sunshine.
Light snow broke out between 7am-8am this morning and quickly
accumulated to 0.2″ before changing to light rain. Light rain
has continued off and on since, but has only amounted to 0.01″
as measured at the 10am observation.
Temperatures have been rising steadily allowing for much needed
melting to take place after the ice accrual early in the week-
end. We finally went above freezing just after 10am this morning,
for the first time since slipping below that mark between 7am-8am
on Friday.
The wind has been light today out of mainly a southeasterly
direction. Peak gust so far today has only been 15mph!
Visibility has of course been limited today with the light
precipitation in the area, generally 20 miles or less.
The high so far today is 38F, this is 3 degrees above the normal
high of 35F. The low since midnight is 21F, which is 3 degrees
above the normal minimum of 18F.
