Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

SHORT TERM. /NEW/ /This Afternoon Through Monday/
The areas of fog and drizzle that lingered much of the morning has mostly dissipated and will continue to do so as southeast winds increase to between 5-10 mph and surface warming picks up this afternoon. That said, my update went toward cooler guidance today with highs only in the lower-mid 60s, versus national blends going mid 60s-lower 70s. With fairly negligible low level warm advection until later this evening and into Monday, I just couldn't find how we were going to warm that much, especially with little sunshine; though a few peeks may occur late in the day. Otherwise, I left some very low PoPs for light rain south of I-20 and where mid level impulses were tracking that could squeeze out a few hundredths of an inch. The aformentioned low level warm advection does ensue later tonight and bring the stratus and patchy drizzle/light fog back to the area just before daybreak Monday. This change combined with continued southeast winds near 10 mph should result in warmer temperatures tonight in the 50s.
Better chances of rain and a few embedded, non-severe storms increase across areas west of I-35 Monday morning, as isentropic ascent increases in advance of yet another mid level disturbance arriving from Northeast Mexico and West Texas. This disturbance and associated ascent will overspread the entire CWA Monday afternoon. The result will be scattered showers and isolated thunderstorms with high warming back into the 70s, thanks to a few peeks of sunshine during the afternoon hours. Localized heavier downpours are certainly not out of the question with precipitable water values rising to above 1.5" across much of the area, with the I-14 corridor in Central Texas pushing near 2". I do not expect widespread heavy rain or flooding issues, but this may change with time as the week progresses. It will become breezy, particularly across the northern counties where south winds 10 to 15 mph and gusts 20 to 25 mph.
LONG TERM. /Issued 427 AM CDT Sun Apr 5 2020/ /Monday Through Next Weekend/
Persistent southwest flow will maintain a steady stream of mid and high clouds much of the week. An embedded impulse on Monday may develop some showers and isolated thunderstorms, but no severe weather is expected with this elevated activity. Despite little insolation, low-level warm advection will allow afternoon temperatures to return to the 70s regionwide.
A further warming trend will push highs into the 80s Tuesday and Wednesday, the surface heating amplified by downsloping winds. A significant westerly component to the 700mb winds will guide a dryline near our western frontier Tuesday afternoon, but a corresponding EML intrusion will cap the mT air within the boundary layer. In addition, the veered surface flow east of the dryline should reduce the moisture convergence that might otherwise be able to overcome the inhibition. Half-hearted slight chance PoPs will be confined to Central and East Texas where a few disorganized showers or storms may occur deeper within the humid air.
A similar dryline push may occur on Wednesday, but even greater veering to its east would diminish the moisture discontinuity across the boundary. However, the GFS now suggests a cold front may cross the Red River before sunset Wednesday. This could back the surface flow and draw the unstable air toward the approaching front. There would still be sizable inhibition to overcome, but such a scenario will bear watching in the coming days. At this time range, the consensus still favors a later frontal timing (Wednesday night into Thursday morning) with lesser fanfare.
Extended guidance continues to disagree on the evolution of the storm system now off the coast of California. Its limbo between the polar stream and the subtropical jet still well equatorward of its location will likely continue to confound the models. The speedy GFS maintains a potent shortwave late in the week (now Friday), but its recent tendency to linger troughing well upstream more closely resembles the other operational solutions. This would mean our rain chances would be primarily in the postfrontal air Thursday and Friday, with the eventual arrival of the main system next weekend too far south to significantly impact North Texas.
AVIATION. /NEW/ /18z TAFs/
Concerns: Timing lifting of IFR cigs into MVFR, and even VFR by this evening, before cigs tank before 12z Monday once again. Potential for brief IFR/MVFR vsbys between 09z-15z Monday.
Vsby restrictions in -DZ/BR/FG have finally improved, but with low level warm advection slow, increasing SE winds, and surface warming slower to occur in wake of a departing surface high, IFR cigs have been slower to lift. I have maintain some potential for IFR until 19z-20z this afternoon, with MVFR likely being predominant much of the day, before giving way to VFR cigs this evening at all D10 terminals here in DFW and in Waco.
However, low level southerly flow in the 925mb layer will increase by 06z and the associated warm advection will help to draw MVFR stratus with patchy -DZ and light FG back northward. IFR cigs will return by 13z-14z Monday, before southerly surface winds increase to 10-15 knots by 16z-17z. This will help disperse any -DZ and light FG before 18z. Convective chances do increase after 18z Monday, but confidence was too low at this point to add a 24-30 hour group at DFW and advertise VCSH/VCTS at this time.
