SHORT TERM. (Today through Monday night) Issued at 245 AM MDT Sun Sep 20 2020

Latest upper air analysis shows a ridge over the southern CONUS. The trough is now over Northern Montana extending down into CO. There is a comma shape in the cloud cover ahead of the trough over the High Plains. At the surface a trough/weak front was approaching the eastern CO border. Even with breezy south winds, the haze has persisted through the night east of the CO border, with visibilities ranging from 4 to 9 miles.

Today the surface trough/weak cold front will move through the west half of the forecast area. Ahead of the trough south winds will become breezy, with gusts of 35 MPH. West of the weak front northerly winds will be much lighter, only gusting to 20 MPH around noon then becoming light. Due to a dry environment in place am not expecting anything more than clouds to occur as the weak front moves through. Highs will be slightly cooler west of the front compared to yesterday due to weak CAA occurring. Meanwhile highs will be warmer than yesterday east of the front due to WAA occurring.

Regarding the haze for today, am not too sure if the haze will remain in place or not. If the haze does clear out, the best chance is west of the weak front where the northerly winds will be. The haze may continue to clear to the east through the afternoon. For consistency with surrounding offices, have the haze leaving the forecast area during the afternoon. Confidence of this occurring is moderate. Wouldn't be surprised if the haze remained in place east of the weak front where the air mass will be similar to yesterday.

Tonight the weak front will retrograde back to the west. The surface pressure gradient will relax some during the night. This will allow winds to be lighter than last night but still on the breezy side. Lows will be similar to last night.

Monday the weak front will instead be a surface trough that moves east to roughly the middle of the forecast area before stalling. (With no CCA occurring behind it due to the upper level short wave trough being well to the northeast, believe the surface feature is more of a trough than a front.) Due to a dry environment in place no precipitation is expected with the trough passage. Winds will be breezy east of the trough, but not as strong as today, only gusting 25-30 MPH. Winds to the west of the trough will be light. Highs will be similar to yesterday, or slightly warmer than today for the western half of the forecast area.

Monday night the surface trough will retrograde west, causing the winds to turn to the south. Lows will be a few degrees cooler due to the winds being lighter than the last two nights.

LONG TERM. (Tuesday through Saturday) Issued at 245 AM MDT Sun Sep 20 2020

At the start of the forecast period, forecast guidance shows an upper air disturbance beginning to travel over the Tri-State area on Tuesday. Models show some discrepancy with the timing of the passage of this disturbance. The GFS and ECWMF show the disturbance passing over the area in the late Tuesday afternoon hours while the NAM has delayed its passing to the late evening hours. On Wednesday into Thursday, there is a transition to a northerly flow over the Tri-State area as a positively tilted trough builds over TX with a developing upper air high in the SW CONUS shaping an incoming Pacific NW jet streak into a ridge. Model guidance then shows a cutoff low developing over central TX on Friday with the ridge which has moved over the Northern Plains increasing its influence on the flow over the Tri-State area. At the end of the forecast period, models suggest an upper air trough entering the Great Plains area on Saturday, but there is model discrepancy in the timing and placement of the trough at this time.

Warm and dry conditions are expected to continue at the surface for most of the extended period. There is a slight chance for precipitation for the far western parts of the CWA during Tuesday evening however there is little confidence for this to occur as models do not show a great amount of moisture at this time with the upper air disturbance passing over the area. Forecast guidance also shows a slight chance of precipitation for the Tri-State area on Saturday afternoon ahead of a passing cold front. Models show a possibility for near fire weather conditions for areas along and west of the CO border in the Tri-State area on Friday as forecasted RH values may drop below 20%. Forecasted wind gust values at this time for the area continue to remain below the fire weather criteria by staying near or below 20 mph. This situation will be monitored in case conditions change.

Tuesday through Saturday's high temperatures in the Tri-State area are expected to be in the middle to upper 80s with areas reaching the lower 90s on Tuesday and Friday. Low temperatures for the extended period are expected to be in the lower to middle 50s for the Tri-State area with portions of the Colorado counties of the CWA dropping to the upper 40s on Wednesday and Saturday nights.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
