Scientific Forecaster Discussion
Area forecast discussion
National Weather Service Birmingham Alabama
626 PM CDT Wednesday Oct 22 2014
for 00z aviation.
In terms of the weather across central Alabama today...you really
can't get much better than this. Dry northerly flow continues to
dominate following the passage of a dry cold front. Dewpoints were
being observed in the upper 30s to lower 40s this afternoon. With
ideal radiational cooling expected overnight tonight...very crisp
temperatures are expected by early Thursday morning areawide. Of
course...a few of the very sheltered microclimate locations could
end up observing a very localized frost. However...temperatures
should remain warm enough to prevent any widespread frost tonight.
In terms of the forecast for the foreseeable future...it appears we
won't see any rainfall across central Alabama until November. Upper
level heights will be on the increase through the remainder of the
week as an upper ridge builds over the Southern Plains. Dry
northwesterly flow aloft will dominate through the weekend. With
upper heights on the increase...moderating temperatures will be
expected. Highs are expected to approach the 80 degree mark by this
weekend with continued warm and dry conditions through the end of
the forecast period.
