SHORT TERM /Through tonight/
Issued at 414 AM MDT Tue Apr 16 2024

Upper low is chugging towards the Kansas border at this hour, about as expected. The precip pattern is just a bit more complex, with some showers/storms rotating back on the north side of the low into eastern border areas. That will slide eastward over the next few hours. Meanwhile, the main precip band has been producing showers over the northern mountains much of the night, and that's starting to spread eastward now behind the upper low. The strong northwest winds will pick up with the showers, but there will be a couple of hours of rain at the front of the band, with lighter precip falling into the drying air at the back. This should all be out of Denver by mid morning, and this band will likely be diminishing as the drier air undercuts it on the plains later this morning. The drying/subsidence should be pretty sharp with clearing skies this afternoon. That will allow temperatures to warm up fairly well, unusual for the rear of a vigorous low but this one wasn't connected to deeper cold air on the back side.

Current highlights look about right, with most of the heavy mountain snow this morning. Fort Collins, Greeley, eastern Adams/Arapahoe counties still close to high wind criteria with less further west. Hopefully enough rain to wet the dirt a bit, but we could have a little blowing dust eventually. The winds will likely be decreasing the last couple hours of the afternoon.

We cooled tonight's lows in the mountains just a little as it should be clear with light winds for at least the first half of the night. There will be clouds moving in after midnight.

LONG TERM /Wednesday through Monday/
Issued at 400 AM MDT Tue Apr 16 2024

There's general consensus among ensemble guidance for a more unsettled weather pattern in place later Wednesday through at least the first half of the weekend. Wednesday, temperatures aloft warm slightly which should promote highs a few degrees warmer than Tuesday. An upper level shortwave trough drops across the area Wednesday night. Jet placement will favor increasing ascent and a cold front ahead of it. The front drops south across northeast Colorado in the late afternoon/early evening timeframe. If it comes on the earlier end, this would keep highs a bit cooler. As the wave approaches, moisture increases across the high country with sufficient lapse rates. This will develop showers across the region with higher chances (40-60%) across the northern mountains(snow) and northern border areas(rain). There is marginal instability in place in the mentioned areas to bring some convective showers or a rumble of thunder.

Overnight into Thursday morning, temperatures cool down towards the freezing mark across the lower elevations. Any showers around will mix in with snow toward sunrise in those areas. Overall, coverage will be lower and limited to the northern mountains and border. It will be cooler Thursday in the post-front airmass with NE winds.
There may be a brief lull before the next weak wave moves through Friday bringing down shower chances. Above normal moisture remains in place over Colorado in the fairly zonal flow aloft on Friday and another weak wave will bringing another chance for showers. Right now, there is still uncertainty in the coverage of showers and chances across the plains given the lower confidence in the strength/moisture associated with this second wave. Snow accumulation will be on the light side in some pockets of moderate in higher northern mountains.

Later Saturday, conditions begin to gradually dry out as a weak ridge moves in from the west. This will keep the plains dry with afternoon snow showers in the mountains through early next week.
With ridging aloft, temperatures rebound Sunday and early next week into the 60s across the lower elevations.

AVIATION /06Z TAFS through 06Z Tuesday/
Issued at 1215 AM MDT Tue Apr 16 2024

A band of showers is expected to move through Denver between 10z and 15z, producing ceilings between 2000 and 5000 ft and localized MVFR visibilities. Northwest winds will also increase during that time, with gusts up to 40 knots. After the showers end, expect VFR conditions but the northwest winds will continue through 22z-24z.
By 03z, winds will become typical S/W drainage, but with speeds of 10-20 knots for a few more hours before decreasing to under 12 knots.

FIRE WEATHER
Issued at 414 AM MDT Tue Apr 16 2024

Winds will be quite strong today, but humidities will be higher.
There will be some drying in the afternoon bringing minimum humidities down in the 20-30% range.

Cooler and unsettled pattern is expected through at least the first half of the weekend. This will bring periods of mountain snow and mainly rain showers on the plains. It will be warm/dry Wednesday and marginally breezy which may bring a period of elevated to spotty critical conditions mainly for southern Lincoln County before the front moves through. Relative humidity values stay elevated Thursday through the weekend in most spots(>30%) limiting fire weather conditions.
