Another hot one is expected as high pressure remains located over western Colorado. The airmass has changed little, so temperatures in the mid to upper 90's are again likely. Below shows the near-surface pattern, with a weak east-northeasterly flow at the surface - there is also this same flow at mid-levels. As we saw yesterday, isolated storms will develop with …

Quiet weather today across the region. As indicated below, an area of high pressure is situated over western Colorado. That will spell out sunny skies and warm temperatures in the middle 90's. Scattered storms will be likely across far western Colorado along the western periphery of the ridge, but all dry over the Denver Metro today. Elsewhere, over the Atlantic, …

A tenth to a quarter of an inch of rain fell across many areas yesterday as scattered "popcorn" thundershowers drenched the area with our first significant rainfall in many, many days. Not only did beneficial rains reach some of the actively burning wildfires in the Mountains, a rare tornado formed at near 10,000 feet elevation yesterday afternoon in Park County …

The frequent lightning actually made for a complimentary show alongside the fireworks! A few storms yesterday did reach severe criteria. The map below shows the hail reports from yesterday....up …

The ridge centered across Northeast will be retrograding in the coming days. This means the wave will be moving against the background flow direction in the atmosphere.... in this case, westward. You can watch this process happen in the 500 mb height animation below. Notice the strong ridge shift from the East Coast today into the Four Corners region by this weekend. As this transition happens, we'll see …

We have one more day in the 90's before cooler weather arrives tomorrow.  The 500 mb vorticity map for today shows Colorado in between major weather players. A strong ridge is present across Pennsylvania, with multiple low pressures in Canada and near the Pacific Northwest. A little bit more moisture will be present in the mid-levels of the atmosphere today. …

In the wake of the cold front that moved through yesterday, warmer air is in store for today. The below pattern shows that the area of low pressure has moved into Canada, with the cold front trailing the system to its south and stretching into Minnesota, Kansas, and western Texas. Take note that to the west of the front, over …
