We're waking up to a gloomy, damp and chilly Monday morning -- with cloudy skies, light rain, and the temperature hovering just below 60ºF (16ºC). Rain showers and thunder obviously redeveloped overnight, and I am finding a healthy 0.64" (1.6cm) in the rain gauge since last evening's report. The low temp here at my location in the upper part of town was 54.9F (12.7C), which is very cool for the season.
Unseasonably cool air in the mid- and upper-levels of the atmosphere being brought into our area by a north-northwesterly flow aloft has not been getting along well with an increasing supply of moisture and relatively warmer air in the surface layers of our air mass. This situation has kept us quite unstable the last few days, with these waves of showers and thunder happening on a daily basis. In fact, I've measured about 1.75" (4.4cm) of rain since Wednesday evening -- that's just a drop in the bucket compared to what will be happening once the monsoon kicks in, but it's a noteworthy amount of rain nonetheless.
I'm optimistic that we'll see some sunshine returning today, but it's going to remain unstable enough that there will probably be more shower/thunder development over the course of the next 18 hours or so. Computer models are showing a rather strong push of warmer air in the upper-levels starting tomorrow... and that should give us a period of more stable conditions for a few days. Another major warm-up is on the way during the middle and latter parts of this week, with a good amount of summer sunshine, but also increasing humidity. We can't rule out an isolated PM thundershower at some point either... which kind of goes without saying this time of the year.
