Key Messages:
1. After a cool morning, temperatures will rise well into the 70s
today with 80s mid-week. No rain is expected.
2. A warming trend will continue through the weekend with highs well
into the 80s and continued dry conditions.
Discussion:
Currently, broad troughing is in place across the eastern U.S. with
high pressure centered near the Great Lakes region. This has
promoted subsidence and ideal conditions for radiational cooling
with morning temperatures falling well into the 40s and 50s. Upper
troughing and surface high pressure will lift further to the
northeast during the first half of the week. This will promote a
slight warming trend with mostly sunny conditions and no rain
expected. Overnight radiational cooling will lead to a few more cool
mornings. By late in the week, broad ridging will expand from the
west with troughing to our east gradually lifting away from the
area. This will continue the warming trend with temperatures rising
back above normal through the weekend. Models differ on the large-
scale pattern to our north and west during this time, but moisture
will still remain limited in our area with weak flow. As such, no
rain is forecast through the end of the period.
