Cooler today... The main cold front moved through last evening (did you smell the manure?) and thus today's temperatures will be slightly cooler than yesterday...with a strong emphasis on slightly. As you can see in the 500 mb height and vorticity forecast map below, a deep trough has developed across the Midwest. The chillest of the cooler airmass is only grazing …

A "juicy" atmosphere today The weather system we have been discussing all week long will make its closest approach to Colorado today as it slowly wobbles across northern New Mexico. The weak circulation at 6PM today can be seen at 500 mb below. The key factor resulting from this low pressure will be an influx of deeper moisture from the …

Another day of spotty storms The weather set-up has changed very little in the last day or three across northeast Colorado. A slow-moving cut-off low pressure system continues to meander around the Baja area this morning, with weak southerly flow pushing into our region ahead of this system. Similar to yesterday, there is enough moisture that solar heating will kick-off widely …
