“Seattle weathermen are half-right, 20% of the time.”
So goes the joke anyway.
Putting that skepticism aside, the current long-range weather forecasts for the week of Table Mountain Star Party look very promising, with a forecast of sunny and warm days and relatively mild nights. Ellensburg is forecast to have temperatures in the upper 80’s to low/mid 90’s or better from Tuesday the 21st onwards through the weekend.
The general rule-of-thumb for TMSP is to take around 15 degrees off of the temperatures for Ellensburg and that’s what we get up on the mountain. That’s equating to daytime temps in the 70’s on the hill – almost ideal daytime conditions.
Nighttime temps will be mildly cool – perhaps dipping into the low 40’s early in the week and increasing into the upper 40’s and low 50’s later on. That’s pretty typical TMSP nights.
As always, pack for all weather conditions – from cold to hot – as the weather is still unpredictable.
