Marine Weather and Tide Forecast for Garland, TN

DISCUSSION
(Tonight through next Saturday)
Issued at 1037 PM CDT Sat Apr 18 2026

Today's cold front sits just to the southeast of the Mid-South with current temperatures, as of 10PM, in the upper 40s to mid 50s, much cooler than 24 hours ago. A few lingering, very light post-frontal showers remain, predominantly over northeast Mississippi. Mist is also present across much of the area as dewpoints remain in the mid to upper 40s. As we head into the overnight hours, dewpoints will begin to crash as cool, dry air continues to filter in. Decreased dewpoints should inhibit much fog development, however, saturated soils from today's rainfall may lead to patchy fog overnight as winds go light and calm and skies continue to slowly clear. If fog does develop, it will lift shortly after sunrise. Tomorrow morning's lows will be in the 40s with some areas along the Tennessee and Kentucky border potentially seeing lows in the upper 30s, aided by a swath of CAA.

Tomorrow's highs will be in the upper 60s to lower 70s with cooler and drier air in place and as upper-level northwest flow begins to build over the region. Fire weather concerns will begin to increase tomorrow and Monday as minimum relative humidity values drop into the 25-30% range. Yesterday's wetting rainfall did help to saturate soils slightly, and in combination with light winds will likely inhibit a need to issue a Rangeland Fire Danger Statement tomorrow. Fire danger concerns do increase further, however, on Tuesday as southwest winds begin to increase above 10 mph with wind gusts up to 25 mph and ten hour dead fuel moisture reaches around 10%. A warming trend will also begin Tuesday as return flow and elevated southwest winds usher in warmer air. This trend will continue into mid-week as upper-level ridging from the west begins to build across the Middle Mississippi Valley Wednesday. Afternoon highs will return to the low to mid 80s across the Mid-South. This warming trend will also increase dewpoints Wednesday and through the rest of the 7 day period, decreasing fire weather concerns.

Heading into the latter half of the work-week, ensembles are indicating a more wet and unsettled shift in the weather pattern indicating a weak trough and cold front will begin to break down the aforementioned upper-ridging. However, we're still a bit too early to iron out the exact details on this late week system. We do know that rain chances will begin to increase, hopefully helping to chip away at our ongoing drought conditions.

AVIATION
(12Z TAFS)
Issued at 614 AM CDT Sun Apr 19 2026

Patchy dense fog will bring occasional LIFR conditions to MKL for the next hour or so before the fog lifts. Otherwise expect VFR conditions areawide with NW winds around 10 kts with some occasional higher gusts at MKL and TUP. Winds will diminish this evening.

FIRE WEATHER
Issued at 1037 PM CDT Sat Apr 18 2026

Fire weather concerns will be on the rise through Tuesday as minimum relative humidity values drop to 25-30% each day. Recent wetting rains will likely negate the need for a Rangeland Fire Danger Statement through Monday. However, increasing 20ft winds and dead fuel moisture near 10 percent will likely necessitate a need for fire weather products on Tuesday. Increased dewpoints return Wednesday, decreasing fire weather concerns.
