While we have at least a slight chance of mainly afternoon showers and thunderstorms right through the weekend, Friday still remains our best chance. A low pressure center will slowly begin to move to the east on Friday, but will be close enough to give us an area of instability and dynamics across northern Nevada. By Saturday, the initial low moves out of range, but a smaller low will drop down out of the northwest which could kick off a few showers as well. Beyond that, light flow will combine with daytime heating to give the possibility of isolated showers each afternoon into the middle of next week.
There are things that I can take for granted when it comes to meteorological principals that I shouldn’t… especially when it involves people’s vegetable crops. One of the most common mistakes I make is to not communicate the frost possibilities when the forecast overnight low temperature is above the freezing mark. Most people think (logically) that a tomato plant will cool down to the same temperature as the air, and therefore if the air doesn’t get colder than freezing, then neither will the tomato plant. But thermal physics doesn’t work that way, and you ignore thermal physics at your (tomato’s) peril. More tomorrow.
