October Obs 2025

[yotaman]

New month, new obs. Welcome to Autumn.

[WinstonSalemArlington]

CLT is at 81 degrees this hour, the only major observation station in the 80s in the state. GSO and RDU are at 73. It seems CLT has been consistently warmer than other Piedmont stations for months now. What is going on at CLT?

Heat Island effect?

What a beautiful 1st day of October. After a low of 58, we had a high of 76. Dew points in the upper 50's and a brisk NE wind made for a very nice fall day.

[WinstonSalemArlington]

High of 70 today at GSO with mostly sunny early October skies. Let’s see if we go down into the 40s tonight

Perhaps, but if so, it seems to be especially enhanced this year 

[chris21]

44 here currently with the temp falling fast.

[WinstonSalemArlington]

Chilly morning

[marsman]

Low of 50 at 7:32am, high of 77 at 3:38pm.

I know this sub-forum is mostly made up of North Carolina folk, but living in Tallahassee it's the closest I've got.

We're currently under a severe drought after the 3rd driest September on record at TLH. Only ~0.5" of rain fell in September, which came at the end of the month on one day from one thunderstorm. There isn't any drenching rainfall expected in the next week or so, though scattered rainfall chances at least increase with a bit more southerly flow this weekend and early next week.

Heading into our "dry" season, it could be an early start to the wildfire season as well. We might need a tropical system to really make a dent in the drought here across the Florida Panhandle, only at 10-20% of our normal rainfall in the past 30 days.

 I’m in the SAV area. It’s pretty amazing how fast it has changed here. After ~17” of rain in August and water tables through the roof, I got only ~1” in Sept and see that the map you posted already has me in yellow.

[yotaman]

Low yesterday of 57, today it was 61. Beautiful fall days here.

[GaWx]

 I’m getting some light to moderate showers that are moving W from off the ocean. First rain of the month. The forecast is for scattered showers to continue to occur in the area through the remainder of the night and through tomorrow. There could be a few thunderstorms tomorrow afternoon.

[GaWx]

 Followup to above post:

Followup: rain became moderate to even heavy at times and more continuous the last few hours including some heavy rain in a thunderstorm a little while ago. But so far there’s been no flooding in my location as the totals appear to be no more than 1” so far. Now the precip. elements are moving more SE to NW.

This FFW was released, mainly for N and W parts of my county as my area hasn’t had the 2-3” referenced:

@buckeyefan1please pin. TIA

 I ended up with 0.75” for the period starting Saturday night and ending at sunset yesterday (10/5).

[GaWx]

I’ve been getting off and on rains (mainly on) the last few hours from showers moving WNW from the ocean, including some short periods of heavy.

[yotaman]

Hit a high of 85 yesterday and today.

[NorthHillsWx]

84.4 yesterday 

[GaWx]

Before this morning, I was at 1.10” MTD. Getting a heavy shower the last few minutes.

Edit 8:35PM on 10/8: After that heavy morning shower and some light followup rain at times the rest of the day (10/7), I ended up with ~0.9. That got me to 2” MTD, which is already near double my Sept. total!

 No rain fell through the daylight hours of 10/8.

[NorthHillsWx]

0.00” MTD and, shocker, the front looks to be drying out for tomorrow 

[WinstonSalemArlington]

I’m sick of summer overtime. Bring on the Cold Front!

One. More. Day. Thursday can’t get here soon enough it’s going to feel wonderful 

[NorthHillsWx]

What looked like a sure fire 1/2” all week with the frontal passage has evaporated literally into a chance of not getting anything. Also, the low keeps trending east. Places west of 95 are out of the game

[NorthHillsWx]

Well… it happened. Rained for about 15 minutes but did not receive anything measurable. 0.00” MTD hangs on

[GaWx]

 If it holds together, a band of light to moderate rain with embedded heavy showers will arrive here in about an hour and last ~an hour.

Edit: it dried up before it got to this area.

[GaWx]

A 10.4 ft high tide is being forecasted for Ft. Pulaski for late Friday morning:

 

 

 That would be tied for the 7th highest tide on record there going back ~90 years, tied with the 8/11/1940 hurricane. It would be only barely lower than the highest tide on record there not associated with a TC, which is the 10.45’ of 11/7/2021!
 

 This is the longest coastal flooding discussion I can ever recall being released by KCHS:

TIDES/COASTAL FLOODING

THE FOLLOWING DISCUSSION IS FOR COASTAL CHARLESTON AND COLLETON  
COUNTIES, ALONG WITH TIDAL BERKELEY COUNTY AS THEIR IMPACTS ARE  
TIED TO THE CHARLESTON HARBOR TIDE GAGE, FOR THE REMAINDER OF  
OUR SOUTHEAST COAST PLEASE SEE THE NEXT DISCUSSION. MAJOR  
COASTAL FLOODING IS POSSIBLE THURSDAY MORNING AS KING TIDES  
CONTINUE, WITH ASTRO TIDES OF 7.06 FT MLLW, WHICH BY ITSELF IS  
ALREADY ABOVE MINOR FLOOD STAGE, TIDAL DEPARTURES OF 1 FOOT ARE  
EXPECTED WHICH WILL BRING THE TIDE FORECAST OVER 8 FEET MLLW,  
WITH THE CURRENT FORECAST AT 8.1 FT MLLW. AT THESE LEVELS,  
WIDESPREAD AND HIGHLY IMPACTFUL COASTAL FLOODING OCCURS IN  
DOWNTOWN CHARLESTON WITH NUMEROUS ROADS FLOODED AND IMPASSABLE  
AND WATER ENTERING SOME STRUCTURES. IMPACTS ALSO INCLUDE EROSION  
AT AREA BEACHES, WITH LIMITED TO NO ACCESS TO DOCKS, PIERS, AND  
SOME ISLANDS. MAJOR FLOOD STAGE AT THE CHARLESTON HARBOR  
RESULTS IN MINOR COASTAL FLOODING IN TIDAL BERKELEY COUNTY.  

WHILE MODERATE COASTAL FLOODING IS AGAIN EXPECTED LATE THURSDAY  
EVENING AS DEPARTURES RISE THROUGHOUT THE DAY AS STRONG  
NORTHEASTERLY WINDS DEVELOP, WE ARE MOST CONCERNED FOR LATE  
FRIDAY MORNING'S HIGH TIDE AS STRONG NORTHEAST WINDS CONTINUE  
AND ASTRO TIDE FALLING TO JUST BELOW 7 FT MLLW, WHICH MAY AGAIN  
RESULT IN MAJOR COASTAL FLOODING. THIS IS WHEN THE HIGHEST TIDE  
IS EXPECTED AS DEPARTURES RISE TO NEAR 1.5 FT, WHICH SHOULD  
BRING THE TIDE GAGE UP TO NEAR 8.5 FT MLLW. WHILE CONFIDENCE IS  
HIGH IN MAJOR FLOOD STAGE BEING REACHED, MINOR FLUCTUATIONS IN  
WIND DIRECTION AND WIND SPEED AROUND HIGH TIDE WILL ULTIMATELY  
DETERMINE JUST HOW HIGH ABOVE 8 FEET WE GO, WITH NORTHEAST WINDS  
RESULTING IN HIGHER READINGS ABOVE 8.5 FT MLLW AND MORE  
NORTHERLY WINDS KEEPING US CLOSER TO 8.0 FT MLLW. IF WE WERE TO  
REACH 8.5 FT MLLW, MODERATE COASTAL FLOODING IS EXPECTED IN  
TIDAL BERKELEY COUNTY. FOR LATE FRIDAY EVENING THE ASTRO TIDE  
DROPS TO 5.6 FT MLLW RESULTING MINOR/MODERATE COASTAL FLOODING  
EXPECTED, WITH ANOTHER CHANCE FOR MAJOR COASTAL FLOODING LATE  
SATURDAY MORNING INTO THE EARLY AFTERNOON HOURS AS ASTRO TIDE  
PEAKS NEAR 6.72 FT MLLW, THOUGH WE'LL NEED TO SEE HOW THE TIDAL  
DEPARTURES END UP TRENDING AS THE COASTAL LOW DEVELOPS TO OUR  
SOUTH. DUE TO THE RISK OF MAJOR COASTAL FLOODING, A COASTAL  
FLOOD WATCH HAS BEEN ISSUED FOR COASTAL CHARLESTON AND COLLETON  
COUNTIES, VALID FROM 8 AM THURSDAY THROUGH 3 PM FRIDAY.

AT FORT PULASKI, WHICH IMPACTS AREAS FROM BEAUFORT COUNTY IN  
SOUTH CAROLINA DOWN TO MCINTOSH COUNTY IN GEORGIA, LATE THURSDAY  
MORNING'S ASTRONOMICAL TIDE OF 9.1 FT MLLW COMBINED WITH TIDAL  
DEPARTURES OF JUST UNDER A FOOT WILL BRING THE AREA RIGHT TO  
MODERATE FLOOD STAGE, WITH THE CURRENT FORECAST CRESTING AT 10  
FT MLLW (MODERATE FLOOD STAGE). AT THESE LEVELS, HIGHWAY-80  
CONNECTING TO TYBEE ISLAND STARTS TO SEE WATER ON IT AND  
NUMEROUS ROADS BECOME IMPASSABLE SUCH AS SHIPYARD ROAD,  
ISOLATING RESIDENTS ON BURNSIDE ISLAND.FLOODING WILL ALSO  
IMPACT AREAS ON TYBEE ISLAND, WILMINGTON ISLAND, THE COFFEE  
BLUFF COMMUNITY, OSSABAW ISLAND, SAPELO ISLAND, PORTIONS OF  
HIGHWAY 17 SOUTH OF DARIEN. IN BRYAN COUNTY, WATER COULD BREACH  
DOCKS NEAR FT MCALLISTER AND FLOODING IMPACTING PORTIONS OF MILL  
HILL ROAD. IN LIBERTY COUNTY, FLOODING IMPACTS THE HALFMOON  
LANDING AREA AND CATTLE HAMMOCK ROAD NEAR BERMUDA BLUFF  
SUBDIVISION.  

WE WILL LIKELY SEE MINOR COASTAL FLOODING LATE THURSDAY EVENING  
AS ASTRO TIDE PEAKS AT 7.74 FT MLLW, WITH TIDAL DEPARTURES  
RISING THROUGHOUT THE DAY CLOSE TO 2 FT. SIMILAR TO CHARLESTON,  
THE TIDE OF GREATEST CONCERN OCCURS LATE FRIDAY MORNING, AS THE  
ASTRO TIDE IS AT 8.91 FT MLLW AND WITH THE CONTINUED STRONG  
GRADIENT WINDS ELEVATED TIDAL DEPARTURES IS EXPECTED. CURRENT  
FORECAST PEAKS AT 10.4 FT MLLW, BUT AS DISCUSSED ABOVE, THE  
EXACT WIND DIRECTION AND SPEED IS GOING TO PLAY A BIG ROLE IN  
HOW HIGH ABOVE 10 FT MLLW THE TIDE GAGE WILL GO. IF THE WIND  
DIRECTION WERE TO SHIFT CLOSER TO NORTHERLY, TIDAL READINGS  
CLOSER TO 10 FT MLLW WOULD BE EXPECTED, WHEREAS NORTHEASTERLY  
WINDS ARE CURRENTLY EXPECTED RESULTING IN THE FORECAST OF 10.4  
FT MLLW. AS THE TIDAL READINGS APPROACH 10.5 FT MLLW, COASTAL  
FLOODING IMPACTS EXPAND ALONG THE ENTIRE SOUTHEAST GEORGIA  
COAST. WILL LIKELY SEE A BREAK FROM COASTAL FLOODING LATE FRIDAY  
EVENING AS THE ASTRO TIDES FALLS TO 7.41 FT MLLW, THOUGH THERE  
IS A RISK FOR ANOTHER ROUND OF MODERATE COASTAL FLOODING.  
HOWEVER, AS MENTIONED ABOVE, WILL NEED TO SEE HOW THE TIDAL  
DEPARTURES TREND AS THE COASTAL LOW DEVELOPS TO OUR SOUTH.

High of 83 today. Dew points on the mid 70's made it feel very humid out. Picked up .01" from a very brief shower.
