Marine Weather and Tide Forecast for Princeton, TX

SHORT TERM
/NEW/ Update: This afternoon's light rain in East Texas is quickly diminishing this evening, with only a few sprinkles possible near and east of I-35 the next couple of hours. With this evening's update, have introduced a mention of patchy fog overnight and early tomorrow morning across portions of East Texas where pooled low-level moisture near the departing low pressure system may be sufficient for fog development. The remainder of the short term period should be rather tranquil, with a cool and pleasant night followed by the onset of a warming trend tomorrow.

Previous Discussion: /Through Monday/

Widespread low and high clouds have filtered over much of East Texas this afternoon as a slug of moisture on the western periphery of an upper low spreads over the region. Isolated to widely scattered showers (20-40% coverage) are ongoing and are expected beneath this cloud deck through the early evening hours, primarily east of the I-35/I-35E corridor. North winds around 10-15 mph will prevail through the remainder of today, so enjoy these seasonably cool temperatures in the 70s while they last before the furnace turns on later this week.

Mid-level ridging will build in behind the upper low as it shifts northeast Monday into Tuesday bringing this period of below-normal temperatures to an end. Winds will be slow to turn back out of the south during the day Monday, but plentiful sunshine and increasing mid-level heights will lead to temperatures in the upper 70s to mid 80s across much of the region Monday afternoon. Temperatures will likely peak in the upper 80s for a few locations across western Central Texas where west-southwesterly flow will advect 15-18 degreeC 850mb temperatures Monday afternoon. The heat will only continue to build through midweek with record-breaking high temperatures likely by Wednesday.

LONG TERM
/Issued 1252 PM CDT Sun May 11 2025/ Update: Little has changed to the long-term forecast. Ridging aloft and breezy west-southwest flow will allow temperatures to soar into the 90s and low 100s region-wide Tuesday and Wednesday with widespread record-breaking temperatures likely Wednesday afternoon. Unseasonable warmth will continue through the end of the work week, but a frontal system may offer a reprieve from the heat for some along/north of I-20 late in the work week. A more active weather pattern will also bring increased chances for thunderstorms to much of North and Central Texas in the late Friday-Sunday timeframe. Severe weather is looking more and more probable across parts of the Southern Plains in the May 16-20 time period, so make sure to follow the forecast closely over the coming days.

Previous Discussion: /Monday Night Onward/

Ridging aloft at the start of the work week will remain in place through the midweek period, boosting temperatures to well-above normal values Tuesday through Thursday. High temperatures ranging from the mid 80s near Paris to around 100 along the Colorado River on Tuesday will climb several more degrees on Wednesday, thanks to southwest/downslope flow adding to the equation. Wednesday highs will range from the low 90s near Paris to 102-105 along the Colorado River. Record high temperatures at the official climate locations of DFW and Waco will most likely be broken, as both locations have forecast highs around 100 with record highs of 95 and 96 respectively.

The ridge will shift east on Thursday as an upper low moves through the Northern and Central Plains, knocking several degrees off temperatures (it will still be hot with highs in the 90s).
This eastward pattern shift will set us up for some convection heading into next weekend. The movement of the low will drag a dryline east into the Big Country and push a weak cold front south through Oklahoma. Each of these surface boundaries will provide a focus for thunderstorm development late Friday, with a trailing shortwave being an added lifting mechanism. The location of each boundary will determine exactly where storms initiate, which at this time appears to be near the Red River and along/west of the I-35 corridor. Storms will persist into the evening, before waning overnight with the loss of surface instability.

The shortwave will race off to the east Friday night and Saturday, but a larger scale trough digging southeast through the Great Basin will provide additional opportunities for showers and storms. The trough will develop a closed low while moving slowly east through the southern Rockies, making for an active weather pattern next weekend through early the following week. Severe weather, though not guaranteed, is a good bet at some point during the Friday to next Monday period (May 16-19) and we will gather more specifics over the next several days.

AVIATION
/NEW/ /00z TAFs/

Mid cloud cover at 8-12 kft will steadily thin out tonight with VFR prevailing. Some fog development is expected by early tomorrow morning in parts of East Texas, but visibility reductions are expected to remain east of the TAF sites at this time. A light north wind at 10 kts will continue through tomorrow before transitioning to southeasterly in the evening, and this wind shift has been introduced in the extended portion of the DFW TAF.
