Marine Weather and Tide Forecast for Eagle, CO

SHORT TERM /THROUGH FRIDAY NIGHT/
Issued at 215 PM MDT Thu May 22 2025

The H500 hand analysis map this morning has a blocky/omega pattern across the high latitudes transitioning to a more progressive one across the CONUS. This flatter weather pattern will continue to support deep mixing leading to breezy afternoons combined with low humidity as temperatures run around 10 degrees above normal.
Moisture transport vectors suggest some Pacific moisture being entrained in this flow which is leading to slightly agitated CU field this afternoon. There could be some virga that develops under some of the stronger vertical updrafts but with the extremely dry boundary layer should prevent any measurable precipitation from reaching the ground. This remains unchanged for tomorrow with hot...dry and windy conditions bringing another round of critical fire weather conditions across portions of eastern Utah in the afternoon. Virga and a very low probability of a shower (<20%) will be possible near the Wyoming border tomorrow afternoon. The blocky high latitude pattern will fold southward by tomorrow evening as an upstream trough begins to form over the Intermountain West. This will begin to shift more dynamics and elevated moisture into our CWA by the weekend and bring slightly cooler temperatures and slightly higher precipitation chances.

LONG TERM /SATURDAY THROUGH THURSDAY/
Issued at 215 PM MDT Thu May 22 2025

The warm, dry, and windy conditions expected during the short term forecast period will gradually diminish over the weekend, reducing fire weather concerns. Gusty winds will still be possible on Saturday as strong winds aloft continue to mix down in the afternoon. Overnight Saturday into Sunday the strong winds aloft move to the east of our region. This, along with a weaker pressure gradient, will reduce afternoon wind gusts through the long term beginning Sunday. On Saturday PWAT anomalies climb from below to above normal north of I-70 due to moisture advection. As a result, isolated showers and storms will be possible on Saturday where the moisture is available north of I-70. A passing disturbance and increased moisture advection on Sunday will help to support elevated PoPs north of I-70 and along the Divide. Through the remainder of the long term afternoon showers and storms are possible each day, but PoPs look to be focused along the Divide. High temperatures on Saturday will be 5 to 10 degrees above normal before falling to near normal on Sunday. Beyond Sunday temperatures will gradually climb back to 5 to 10 degrees above normal across the region.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
Issued at 515 PM MDT Thu May 22 2025

Gusty winds of 30 to 35 mph will subside over the next few hours leading to a tranquil overnight. Some high clouds will drift overhead but not pose any concern. Rinse and repeat tomorrow with another afternoon and evening with gusty southwest winds of 30 to 35 mph expected. VFR conditions will remain in place.

FIRE WEATHER
Issued at 215 PM MDT Thu May 22 2025

Well above normal temperatures into Friday will lead to deep mixing and promote gusty afternoon winds and low humidity in the single digits and teens. This will lead to critical fire weather conditions where fuels are dry which at the current time is over portions of eastern Utah and far western Colorado. Temperatures and winds will be trending downward through the weekend with critical fire weather areas becoming more localized. Afternoon showers will be possible but winds are more likely than wetting rainfall.
