AgWeatherNet Weekly Weather Outlook for February 2 to February 8, 2013

Mostly Dry This Weekend; Weak Storm Systems To Arrive by Mid Next Week

High pressure will control the weather on Saturday, as an inversion attempts to set up over lowland areas of central Washington. However, the ridge of high pressure will quickly become suppressed as westerly flow strengthens and drops south toward northwestern Washington early next week. A couple of weak weather systems will eventually move through Washington next week, bringing some rain to western Washington and rain or snow and cooling to the mountains. By late next week and into the weekend, high pressure will become re-established, which should lead to generally dry weather through at least mid month.

Temperatures
  • Seasonal in the lowlands and mild in the mountains this weekend, especially on Saturday.
  • Becoming cooler in the mountains by next Wednesday.

Rainfall
  • Dry on Saturday.
  • A slight chance of rain in northwest Washington beginning on Sunday, otherwise mostly dry.
  • Rain likely for western Washington, with a chance of rain or snow east of the Cascades starting Tuesday or Wednesday.

Wind
  • Mainly light through early Tuesday.
  • Possibly becoming breezy around Tuesday or Wednesday.

Frost Risk Summary
  • This weekend and next week: Moderate to high risk east of the Cascades.
  • Low to moderate risk west of the Cascades.

8 to 14 Day Outlook - February 9 to February 15
  • High pressure looks to dominate the weather starting next weekend and continuing through at least mid February. This pattern favors dry and benign weather, with potentially mild weather in the mountains. Inversions could be an issue in central Washington, although the strengthening February sun suggests that a repeat of the prolonged cold and stagnant mid January period is unlikely.
