Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – July 2, 2019

This content was originally published by the Longmont Observer and is licensed under a Creative Commons license.

In Brief:

We hover near 90F for four more days then hop around in the 80'sF more beyond that. There are daily chances of afternoon storms, but the severe storm possibility is still on the table for Longmont today (Tuesday).

Forecast Discussion:

The moisture will be down just a bit today (Tuesday) but mountain thunderstorms moving east in the afternoon are to be expected again (Figure 1). The conditions for severe weather from roughly Longmont northward exist again for hail and high winds (Figure 2). If this gets redrawn in the morning, I'll update things here. We climb to the upper 80'sF before the clouds and showers move in.

The Longer Range Forecast:

We have about 4 days straight with highs hovering near 90F through Friday - then we drop to the lower 80'sF for a day Saturday (Figure 3).

The 4th of July Forecast:

It is looking more like a day with a high at 90F and a low at 58F. At 9pm, when fireworks are about to begin, we should have cooled to 75F with a chance of mosquitoes and 10% chance of remaining showers (Figure 3).

The Longer Longer Range Forecast:

Glancing ahead to the entirety of July, the weather channel is predicting normal temperatures (Figure 4) and above normal precipitation (Figure 5). The European model (not shown) has us much wetter than normal and below normal as temperatures go (sounds like the July version of June!).

We'll see!
