.DISCUSSION...
Issued at 407 AM EDT Sat Sep 5 2026
- A few showers are possible today
Feel most areas will remain dry today, but it is not out of the
realm of possibilities to see a few light showers today. Current
regional radar loops confirm a showers continue across the area
despite the deeper convection pushing south an hour or two ago.
The showers will be associated with weak shortwave dropping south
through the northern flow aloft. Residual moisture hangs on into
at least the midday hours before drier air sweeps in this
afternoon and evening. Only have 20-30 pct chances for a shower
mainly this morning.
- High confidence in dry weather this afternoon through Tuesday
BUFKIT overviews and ensemble members of the GFS and ECMWF confirm
that there is very little chance for precipitation in our area
from this evening through Tuesday. For those that have received
heavy rain in the last 3-5 days it will give those areas a chance
to dry out.
- Temperatures to be fairly close to normals through the period
Temperatures will be close to normal for this time of year through
the 7 day forecast period (Normals for today: highs in the upper
70s / lows in the upper 50s). We will see highs push into the 80s
once again early next week in the southerly flow ahead of a mid
week cold front.
