why truck struggles to accelerate in wet weater ?
Check your ignition coils (coil-on-plug) if it's cracked moisture maybe getting in it. causing the cylinder to misfire. you may also have a short on one of your 02 sensor
Also recommend checking coils
a can of wd-40 when this problem occurs will "displace" the water~ and problems in the high-tension ignition wires will be okay until you can switch 'em out for new ones~
