.DISCUSSION...
Issued at 1247 AM EDT Fri Oct 3 2025
Surface high pressure is centered off of the southern New England
coast. Meanwhile, ridging aloft is broadening across the majority
of the US, with the exception of a digging trough over the PNW.
Precipitation will be locked primarily to the Gulf, Florida, and
nearby locations the next few days. Under this pattern, we will
continue with dry weather, near seasonable temperatures, and at
least a couple of lower humidity days. High pressure locked to the
east will bring some breezy nights to the higher elevations
through early next week. The aforementioned trough will deepen
and move eastward, compressing the ridge, eventually changing our
weather pattern next week.
Today and tomorrow will feel drier, with dew points remaining
below 60. Although temperatures won`t rise all too much, the
humidity will crank back up beginning Sunday and remain elevated
in the mid to upper 60s through about Wednesday. The current
forecast in comparison to the past few nights, now suggests we may
hold onto the dry weather through the entire weekend. The gulf
moisture may not infringe on our southern borders until possibly
Monday. A cold front may impact the region Tuesday into Wednesday,
returning the chance for area-wide precipitation.
