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.
AVIATION /12Z TAFS THROUGH 12Z SUNDAY/
Issued at 709 AM EDT Sat Sep 5 2026

We will see a slow and steady improvement this morning and early afternoon with conditions going back to VFR between 17z and 20z. A few showers may move through the TAF sites this morning, but the activity should remain scattered and light. VFR weather is forecast tonight.
