Current forecast remains on track, including dew points. Some sprinkles are possible in the FL Suwanee Valley this afternoon.

.SHORT TERM & Long Term (Today through Friday) Issued at 224am EDT Sat Oct 24 2026

High pressure over the Northeast US will slide down the Appalachians into the Mid-Atlantic by Sunday. Meanwhile, an area of low pressure will develop over the Bahamas. This will tighten the pressure gradient across the area this weekend into early next week, resulting in breezy conditions. Northeasterly winds around 10-20 mph with gusts up to 25 mph are expected this afternoon, with a few gusts to 30 mph in the eastern Big Bend and I-75 corridor in GA. Otherwise, it will be mainly sunny today with highs in the mid to upper 70s. Given the wind staying a bit elevated overnight, lows won't be as cool as previous nights, only in the 50s to low 60s.

Sunday will be the apex of the breezy conditions as the pressure gradient is at its tightest. Northeasterly winds will be around 15- 20 mph with gusts around 30 mph (possibly higher in the southeast Big Bend). There will be a bit of a low-level jet around 30-35 kt Sunday morning, but most model soundings show a rather stout inversion around 950 mb just below this LLJ. This should prevent the strongest winds from mixing down before the inversion breaks and the LLJ weakens. Thus, the chances for reaching Wind Advisory criteria appears very low at this time. Still expecting dry weather otherwise with highs in the mid to upper 70s and lows in the 50s to low 60s.

The pressure gradient relaxes Monday as high pressure over the Appalachians weakens a bit and shifts into the Ohio Valley, so we won't be quite as breezy. A little bit of ridging also builds in aloft, so highs will creep up closer to 80 with lows in the upper 40s to mid 50s Monday and Tuesday. Later in the week, we'll see a slight uptick in moisture as our ridge weakens and moves east of the area. Our temperatures will nudge upward a bit more, especially our lows. However, our next substantial rain chances likely won't arrive during the next 7 days.

Long Term
Marine
Issued at 224am EDT Sat Oct 24 2026

A prolonged period of hazardous marine conditions continues through early next week with fresh to strong northeasterly breezes of 20-25 kt and gusts to 30 kt. Small Craft Advisories continue for the Gulf waters through Tuesday afternoon, but could be extended further into next week. Rough seas will also continue with wave heigheights of 5 to 8 feet expected.

Fire Weather
Issued at 224am EDT Sat Oct 24 2026

Critical to near-critical RH is expected this afternoon across the AL and GA zones as well as the Apalachicola NF as RH bottoms out in the low to mid 20s. This could result in elevated fire concerns this afternoon, especially in the Alabama and Georgia zones where the combination of critically low RH and elevated winds exists. Elsewhere, RH will be mostly in the low to mid 30s. Transport winds will increase out of the NE this afternoon to 10-15 mph. This will yield good dispersions are-wide. Over the weekend, transport winds increase a bit more out of the northeast to 15-20 mph. However, mixing heigheights will be a bit lower. Thus, high dispersions are mainly confined to the Apalachicola NF and southeast Big Bend with good dispersions elsewhere. Min RH values will mainly be in the 30s both afternoons.

Hydrology
Issued at 224am EDT Sat Oct 24 2026

Flooding is not expected over the next 7 days.
