4/19 Technical Discussion

Synopsis:

Rain with a few pockets of sunshine will be the rule this week.  The low pressure system currently affecting the state will be around until Thursday, when we have one brief day of sunshine. The next system to affect the area will begin to move in on Friday, and currently its track is forecasted to be north of the state.

Short-term:

The warm front expected to pass through the region overnight tonight means that low temeratures for the night will be only a degree or two lower than the high temperatures today. With our entry into the warm sector, we will see high temperatures tomorrow. These high temperatures will provide the fuel for thunderstorms, and currently the SPC has a slight convective outlook for the eastern half of the state. The southeast will be the region where severe weather is most likely to occur. Once the cold front passes, wind could be an issue behind it. The SREF wind model is showing the potential for winds between 25 and 35mph over the center portions of the state on Wednesday evening.


Long-term:

Thursday will be breezy and otherwise partly cloudy, before the next system rolls in for Friday. Currently the GFS and the WRF have the precipitation arriving far ahead of the low pressure center, which is forecasted to pass to our north on Saturday afternoon/evening. We forecasted scattered showers throughout the weekend, though we expect this to become more refined as the week progresses. The beginning of next week looks interesting, with the GFS forecasting an extratropical cyclone to percolate over the Great Plains before moving eastward slowly.
