Long Term
(Wednesday through Sunday)

The extended forecast will start with a post-frontal atmosphere with a dry and stable air mass, bringing sunshine and springtime conditions. However, this will be a short break in the active pattern we have in store for next week. Daytime highs on Wednesday will remain near normal values for this time of year, around the low 80s.

Enhanced flow aloft will start to return on Thursday as an enhanced, long wave trough starts to move into our region. For Thursday, Probability of Precipitation will remain on the lower end, around 20%. The main synoptic features that will be impacting our region will be a surface low that will begin to form in the southern great plains and the longwave trough mentioned above. The low will be pulling large amounts of warm, moist air from the Gulf north. Leading to well above-normal low temperatures, around 15 to 20 degrees above normal, along with overcast skies. We could see some high minimum temperatures recored or broken Thursday through Saturday night.

As for our atmospheric profile, forecast soundings show the impressive speed at which our atmosphere will recover moisture, with PWATs (Precipitable Waters) going from 0.9 inches at 12Z on the 7th to 1.81 inches at 12Z on the 8th. Our atmosphere will also become more destabilized with the K index going from -1 to 37 during the same time period. Aloft, both the ECMWF (European Centre for Medium-Range Weather Forecasts) and GFS (Global Forecast System) show the main trough axis moving through our region with a strong jet streak over 100 kts at 250 mb. At the same time, winds at the surface will be from the south. If this forecast holds, we will be looking at a possible springtime severe weather setup with high shear but low CAPE. However, there are still a lot of questions about this "maybe" event, especially with regards to the timing of the front. The front passage will most likely be the main forcing mechanism and will need to have enough daytime heating for instability to build to concerning levels. Overall, there is still a lot of time for the details to take shape, so we will need to keep an eye on this system as it continues to develop over the next few days.

After the passage of the front, our temperatures will cool back down, which will be a nice bonus for those that aren't ready for summer to start. With high temperatures in the upper 60s and lows back in the mid- to upper 40s.


Onshore flow will continue through the period. Dense marine fog will continue across the coastal lakes and bays and coastal waters out 20 nautical miles. Patchy fog likely to linger this afternoon, with areas of dense marine fog spreading over the nearshore waters, lakes and bays once again tonight though Monday morning. An approaching upper level disturbance will bring widespread showers and thunderstorms Monday afternoon through Tuesday morning, with no precipitation expected Tuesday night and Wednesday. Another upper level disturbance approaching the area Thursday will bring another chance of showers and thunderstorms.
