|CATCHY DRAWER AND STICKY DOOR
METEOROLOGIST JEFF HABY
WEATHER FOLKLORE: "Catchy drawer and sticky door, Coming rain will pour and pour"
APPLICABILITY: Just about anywhere heavy rain can occur
ANALYSIS AND INTERPRETATION: The "stickiness" occurs due to high humidity.
Heavy rain needs plenty of
moisture to fuel the storms. High
dewpoints along with a high
relative humidity are needed to create
the stickiness. With a very sticky airmass, a
lifting mechanism will be able to generate heavy rain.
Notice the lore refers to the rain as "pouring". This pouring fits heavy
convective rainfall in
maritime tropical airmasses.
If no lifting mechanisms are in place, the weather can be very sticky for many days without rain occurring. The
lore mentions "coming rain"- thus the rain may not come. The lore is saying that if the
rain does come, it will be very heavy.
You may have seen these statues that change color (such as red being rain and blue being fair weather) or
gauges that point to either (fair, changing, or stormy). These devices are simply based upon relative humidity. The logic
behind the devices is the higher the relative humidity the more likely rain is.
