The active weather pattern that seems to be bringing more clouds than sun and plenty of chances for rain looks like it will continue at least for another week, but there are some signs that the pattern might be changing.

Currently we see a very strong jet stream coming in off the Pacific and zooming along the border. This powerful jet has been bringing in a series of low-pressure systems from the Pacific every couple of days. This jet has also set up a north-south boundary in the upper atmosphere, the focus of cloud and thunderstorm development.

We will see another significant storm system move in late on Thursday. The latest model run has some showers and thunderstorms push through southern regions late Thursday into Friday morning. The system then shifts southward, giving us a break later on Friday into Saturday. Then the battle begins between high pressure to our north and the southern system. At first the models had the northern high win out, which kept us sunny and dry over the weekend. The models now show the southern low pushing northeast, bringing showers and thunderstorms back into our region late Saturday and Sunday. Let’s keep our figures crossed that the high wins out.

It does finally look like things will dry out a little bit early next week, as high pressure finally moves into our region. Temperatures look to be seasonable next week and if we do get some good sunshine, things should finally be able to dry out. The question is, will it be too little too late?

Usual temperature range for this period: Highs: 18 to 28 C. Lows: 6 to 14 C.
