Why does the temperature drop a few degrees just before sunrise?

Right before sunrise (where you are) it IS sunrise just over the horizon. There, the sun is coming up and beginning to warm. This causes an outward expansion of air which in turn disturbs the air in areas around it (where you are) This disturbance stirs the air up, causing air close to the surface, which has been able to stay slightly warmer (due to earth temperature, industry, nearby bodies of water, condensation of dew etc, all of which release small amounts of energy to their environment) to mix with air further from the surface, which didn't have these warming influences. Now some of that colder "high" air is on the surface, so the surface air temperature drops slightly. This phenomenon is known as the Solar Semi-diurnal Tide.
There is another cause of this phenomenon, and that is something known as the latent heat of vaporization. When the Sun's rays first hit dew or frost on the ground, but before the radiant heating of the Earth has begun, the Sun's rays actually begin the process of evaporation and it is this process of evaporation that removes heat from the environment thus registering a noticeable drop in temperature. Obviously, the conditions would have to be just right for this phenomenon to occur, but it does happen.

What is the temperature at 25000 feet with a ground temperature of 62 degrees and a temperature drop of 2 degrees for every 1000 feet?
11 degrees
Which temperature is 20 degrees colder than 44 F?
If the temperature is 44F and the temperature drops 20 degrees, the temperature would be 24. Subtract the temperature drop from the starting temperature.
Can the Mars night temperature drop to -200 degrees?
The temperature might get that cold (-200°F or -129°C), but the observed minimum is only about -87°C (-125°F) which is pretty cold.
Does the temperature rise or drop in the stratosphere?
drop
Is there a corresponding 6.5 degrees Celsius temperature drop for each kilometer of altitude?
Yes. Temperatures cool at a rate about 6.5 Celsius degrees per kilometer of altitude. This is straight from a 6th grade book.
Why does the temperature drop at sunrise?
The lowest temperatures of the day are recorded just before sunrise. This is because the earth continues to cool once the sun has set until the sun rises again
