Synopsis - A tight gradient between high pressure to the east and low pressure over the plains is bringing about a prolonged period of long fetch across the northern gulf. This modest southerly flow will continue to result in elevated seas into early Monday. A small craft advisory will be in effect for all 0 to 60 nm waters from late tonight through early Sunday morning. The next chance of rainfall comes Sunday when a frontal boundary nears the region, with scattered showers and Thunderstorms expected Sunday through Monday.

New AVIATION
KEY MESSAGES
- A Wind Advisory has been issued for Saturday as breezy to gusty winds are expected. Another may be needed Sunday.
- Very warm and humid conditions this Holiday Weekend. Check on the vulnerable groups when outdoors.
- Shower and thunderstorm chances return for Easter Sunday, some storms may be severe. Unsettled weather continues through the week.
UPDATE
Issued at 941 PM CDT Fri Apr 18 2025
Elevated southeast winds through the night will become breezy once again by late morning Saturday. With the winds staying up, fog is not expected to be an issue. The 19/00z upper air sounding still shows a decent cap in place between 4k and 5k feet. Expect low clouds to form under the cap through the night. With the south winds and clouds, temperatures will not drop too much the remainder of the night with muggy conditions. No changes needed to the forecast at this time.

SHORT TERM
(Tonight through Sunday night)
Issued at 255 PM CDT Fri Apr 18 2025
The warmth and moisture are here! All areas are in the 80s this afternoon. Combined with dewpoints in the mid to upper 60s, it feels rather gross out there. Thankfully the breeze is present helping to make things feel a bit less sticky.
No change in the pattern for tomorrow, except developing low to the north will tighten the pressure gradient further, further increasing daytime wind speeds. Thus, a Wind Advisory has been issued for the I-10 corridor Saturday from 10 AM to 7 PM. As this frontal system starts its march to the southeast tonight and Saturday, expect winds to remain up well into Sunday. Another Wind Advisory may be needed to cover the Holiday daytime hours.
Beyond a windy Easter, there still remains a severe weather threat. Guidance has slowed further with its timing for strong storm arrival to the region. Showery weather should move in from the northwest throughout the morning. Any showers which can deepen enough may carry a localized wind risk, but generally, the greater threat doesn't appear to manifest until the later afternoon and evening.
Storms along the main front start to congeal together and move in from the west in the mid to late afternoon. Severe parameters support convection with a damaging wind risk. There may be some risk there for hail and an isolated tornado, but these scenarios are less likely with the current forecast expectation.
For those with outdoor plans on Saturday: stay cool and hydrated.
Check on those vulnerable populations while outdoors. Plan to breezy to windy conditions.
Sunday: again, very warm and humid with breezy to windy conditions. Light showers may move in through the morning. A slow moving line of storms is expected to start moving through in the afternoon and evening. Plan accordingly, and if you hear thunder, go ahead and move your plans indoors.
11/Calhoun
LONG TERM
(Monday through next Thursday)
Issued at 255 PM CDT Fri Apr 18 2025
Widespread showery activity will continue into Monday as the shortterm frontal system sags overhead. A few rumbles of thunder could be in the mix, but generally speaking, there is no expectation of severe weather. Rather, expect periods of rainfall throughout the day.
All forcing aloft washes out by Tuesday morning allowing the boundary to linger near the I-10 corridor into the midweek. With daytime heating, expect another round of showery weather with a few thunderstorms in the mix.
There could be a few periods of more enhanced weather as weak shortwave pulses move overhead Wednesday and Thursday. Combined with deep Gulf moisture, there could be a localized flood risk in areas where heavy rainfall trains.

AVIATION
(06Z TAFS)
Issued at 1132 PM CDT Fri Apr 18 2025
Not much change in the thinking as far as the aviation forecast goes. Elevated southerly winds will continue through the night with breezy conditions on Saturday with a tight gradient over the area between high pressure east of Florida and a series of lower pressure across the Southern Plains. Gusts will increase after sunrise, then by 19/18z, gusts near or above 25 knots can be expected.
Good size cap in place will keep any significant shower activity away during the period. However, low level moisture and lift from the low level jet will create low cloud decks under the cap with ceilings at the MVFR level from roughly now through 19/18z with ceilings improving to VFR during the afternoon, before decreasing back into MVFR after 20/01z.
