Odd Temp Change Before Spawn

[bassfishkansas]

The water temperature has risen dramatically within the last week and a half (from in the low 40's to the low 60's), and I have been out on the water every single day since Monday (12th). I have been really tearing it up with a red super spot lipless bait. My question is simple: If there was not a gradual rise in water temperature, how long will it be until they start spawning? I assume that they need some time to fatten up, because there has been no real gradual 'prespawn' phase. How long does that period ususlly last? I have been on the lookout for bass beds, but haven't found any so far. It's been either rainy, cloudy, or windy for the last two days. The wind has been up since Wednesday (out of the south), and air temp is around 65 for the last week. Should I be getting ready? Also, I plan to go fishing tomarrow. It will be cloudy and windy (most likely out of the south) and in the mid 60's. The water is stained, and in the upper 50's. My small 23 acre lake has many 'flats' areas on all sides except for by the dam. My favorite spot is by the cove on the southwest side where it turns into the main lake. I know that they bed there sometimes. I have also seen beds on the entire north side last year. What should I tie on? I plan to use my trusty Rayburn Red Super Spot, a Fat Free Guppy, a Big Bite Squirrel Tail worm, a 3/8 oz brown jig, a watermellon 3" tube, and a Tightlines UV Hog. Any suggestions? Thanks!
