Finally Fall?

Today's cooler weather reminded us that it actually is fall and not mid summer. Temperatures have finally started to moderate, and will continue to cool into the weekend. Overall expect highs in the 60s and 70s through the period, with lows dipping into the lower 40s at times.

Early next week the mountains could see their first snowfall of the weekend. A front coming in Monday night is expected to bring some cold air with it which could lower the snow level to the immediate foothills to our west. A chance of rain and cool temperatures are all the is expected for the Denver area.

Beautiful today... Then SNOW!

Things are about to get real interesting around here, and in a hurry. After a picture perfect day today with highs in the low 70s, the bottom will drop tomorrow as cold airmass from Canada dips south during the day bringing Denver a good chance of snow tomorrow afternoon and evening. Although chances are "likely," the NWS thinks accumulations will be light. Just in case the forecast falls apart and it does not snow tomorrow night, we have another decent chance for snow from Friday night through Saturday. Saturday's highs will likely not break the 40 degree mark.

Denver's average first snowfall is October 19th... Looks like this year that could come early. Stay tuned as details for accumulations, temperatures, and timing will continue to get worked out!

Big Changes Brewing

While the first day of Fall is not officially until Tuesday, Monday will feel more like Fall than Summer. Over the last several days forecasters have continued to lower the expected highs on Monday as they continue to tweak the forecast details. As it stands, it looks like we will struggle to make it out of the 50s, and lows will dip into the upper 30s for the first time in quite awhile. Clouds and rain are also looking likely for Monday - but it remains unclear how long the soggy weather will stick around as some models have the low moving through much fast than others. From Monday on there is a general warming trend, the exact track of the low will determine how quickly this occurs. At this point it does not appear that 80s will be returning any time next week.

It shouldn't get cold enough for snow here in Denver. Travel 20 miles west and that could be a completely different story. Looks like this cold front will bring the first blast of winter weather for the Mountains and even some foothill locations.

September

Many thanks our new contributor to Brendan's Weather Blog! In case you missed it, take a moment and check out "The Sweet Smell of Summer" posted by senior editor Jason Fox earlier this week.

Tomorrow begins yet another fantastic month for weather here in Denver, Colorado. We will be a mere 22 days away from the first day of Fall! September traditionally is a very pleasant month - filled with our trademark late summer/early fall weather of clear sunny days, and crisp cool nights. While 90 degree readings are by no means unheard of, for some of you these next stats may be a harsh realization that summer is quickly drawing to a close... Winter weather is not as uncommon in September as you might imagine. The earliest snowfall ever recorded in Denver was September 3rd, 1961 when four inches fell at the old Stapleton Airport. September's largest snowstorm came years later when nine inches of snow fell on September 29th, 1985. The temperature bottomed out at 17 degrees F that night. We have not seen snow in September since 2000. Last year we had a very pleasant (albeit a bit dry) September where the low never dropped below 40.
