Marine Weather and Tide Forecast for Dallas, TX

SHORT TERM
/NEW/ Update: Fine snow grains/flurries continue to fall across much of North Texas and portions of Central Texas. While most of this is very light with little to no accumulation, we have seen perhaps some enhancement downwind of a couple of area lakes this morning. Any lingering snow should dissipate shortly after sunrise, with bitter cold and breezy conditions expected the remainder of the day. The main change with this update was to extend/expand the mention of snow/flurries. Additionally, the Extreme Cold Warning was expanded overnight to include the few counties across our south and east that were previously covered by a Cold Weather Advisory. The warning is now in effect for all of North and Central Texas through Thursday morning.

Previous Discussion: /Through Thursday/

Outside of a few lingering light flurries, wintry precipitation has ceased across the region, and the Winter Weather Advisory was allowed to expire on time at midnight. The freezing line has pushed south and east of the area, with all of North and Central Texas now below freezing. Strong north winds will continue to advect very cold air into the region with low temperatures bottoming out in the single digits and teens for many areas this morning. Dangerous wind chills are expected, ranging from -10F to 10F. While ice accumulations were quite minimal, the strong north winds and dry post-frontal air will continue to sublimate any ice on roadways and other surfaces. However, caution should still be exercised while driving, as a few slick spots will remain possible this morning - mainly on bridges and overpasses.

Dense, low clouds will gradually scatter out late this morning through the afternoon, but strong cold air advection will keep temperatures below freezing for most locations throughout the day with highs in the mid 20s to low 30s. The main exception will be portions of Central Texas where temperatures may reach into the mid 30s, but there is a ~40-50% chance these areas will remain just below freezing as well. Persistent breezy winds will continue to make it feel much colder than it really is, with wind chills only in the teens to 20s.

Dangerous cold is expected again tonight, as overnight lows will plummet into the single digits and teens area-wide. While winds won't be quite as strong as they currently are, wind chills will still fall into the -8F to 8F range. Despite weakening cold air advection on Thursday, the Arctic airmass will be slow to moderate as winds remain out of the north. Many locations will remain below freezing once again, with the exception of portions of Central Texas and the Brazos Valley.

LONG TERM
/Issued 306 AM CST Wed Feb 19 2025/ /Friday Onward/

Modification of the Arctic airmass will continue on Friday as light ESE winds return, with the entire CWA expected to climb above freezing during the afternoon. However, a cold night will still follow with lows dropping into the 24-32 degree range. Low- level moisture will be drawn northward late Friday into Saturday ahead of an approaching positively tilted trough axis. Overcast skies will resume heading into Saturday as a result, along with a potential for light rain across Central Texas during the day. At this time, most guidance supports above-freezing temperatures while this precipitation would be ongoing, although it would certainly be a cold rain with temperatures in the mid and upper 30s. However, small differences in timing could result in a brief window of freezing rain potential across Central Texas on Saturday morning prior to temperatures rising above 32F. Temperatures will warm via warm advection during the daytime as rain expands into parts of North and East Texas before vacating the area to the east Saturday night. The persistent warm advection regime will maintain the warming trend through the rest of the weekend, with highs on Sunday returning to the 60s.

Building heights and more persistent south flow will lead to above normal temperatures heading into next week. Expect highs in the 70s through at least the first half of the week, and perhaps even a few 80s by Tuesday. Low rain chances may accompany a cold frontal passage during the mid or late week period, but this is still uncertain with a very wide spread in guidance beyond Day 7.

AVIATION
/NEW/ /12z TAFs/

Fine snow grains/flurries continue to be observed across much of North Texas. Little to no accumulation is occurring for most areas, with the exception of some minor accumulations downwind of a couple of area lakes. No significant impacts are expected, with any snow/flurries expected to dissipate shortly after sunrise.

MVFR ceilings will gradually lift later this morning, with VFR expected to return by the afternoon. Breezy/gusty north winds will prevail much of the day with wind speeds between 15-20 knots and gusts up to 30 knots. Winds should slightly weaken this evening, but a few gusts between 20-25 knots will likely continue for at least part of the overnight period.
