I19 by the numbers
What the long-run records say about flying here, computed for this airport alone.
I19 reported VFR in 77% of daylight observations over 20 years, about 248 flyable days a year. August is the most reliable month and January the least, with IFR or worse 16% of the time. When conditions drop it is usually low ceilings rather than fog (ceilings under 1,000 ft 7% of hours, visibility under 3 miles 4%).
Snow fell on about 31 days a year. From December to February I19 was IFR or worse 13% of the time, against 5% from June to August.
Thunderstorms were reported on about 57 days a year.
Field elevation is 948 ft, but on a median summer afternoon the air performs like 2,493 ft, 1,545 ft higher. Plan for a longer takeoff roll and a weaker climb from June to August.
Gusts showed up in 18% of hours, typically 8 kt above the steady wind, and the strongest credible gust on record was 52 kt. March is the windiest month (mean 6 kt) and August the calmest.

“Current use” is what the facilitystates; wind components are arithmetic on the current METAR against TRUE headings; status reflects NOTAMs received through SWIM, the tower's TFDM record and the D-ATIS — a runway reads “Open” only with a complete NOTAM picture.
