另外，雖然今天天氣只有十四、五度，但是仍然看到不少學生仍然穿著夏季校服，因為有些學生因為上星期的天氣而轉穿夏季校服，那樣明天應該會看到在發出寒冷天氣警告下仍然穿著夏季校服上學的情景了。

有趣的是見到有女生穿夏季校服 + 外套,
情況同三十幾度一樣

According to HKO, the sun never shines again because of east monsoon.  There is cloudy instead of somewhat sunshine on 4/6/07, and there is another lati-thunderstorm on 4/8/07.  Furthermore, HKO expects only rain/thunderstorm on 4/11/07, but no more suuny days again next 7 days.

The sun never shines again next 7 - 15 days because the east monsoon, and the sun shines in Hong Kong iff there are another 25 degree C days.  Because of the east monsoon, the situation is impossible, thus no sunshine is possible.

Say no more sunshine till next 25 degree days!  However, if there is another sunny period in mid April, then there will be up to 30 degree C!
Try later weather report and check this if it is true!

Thank you for your information, but...
to be honest, your English is quite hard to understand. The sun always shines, doesn't it?

In my opinion, I would like to discuss this point:
"The sun shines iff the day is sunny day."

If the weather in some day that is not a sunny day, in this case, we cannot say the sun shines.

Enjoy the rainny Easter Holiday!
No more sunny days until mid April!

Sorry for the system down, and because the original manu is too long, so let us continue the example in the second page.

4/7: Because of the shower, the partly-sunny situation disappears.  See the next part.
4/9: The partly-sunny day was underway, and the relative humidity (R.H.) is as low as 47 - 48 %.
4/10: Stop the sunshine this day!  Owing to the cold front properties and lati-rain.
4/11: The sun shines again.
4/12: The situation was similar as the one on 4/9, and the R.H. is as low as <40% in day time.    However, the R.H. is normal in night time.
4/15: The situation is similar as the one on 4/9, and another day time yellow fire is available.
4/16: The temperature is as high as 29 degree C.
         One part of sunny period ends.
4/17: Stop the sun owing to the lati-thunderstorm (because of another cold front property).  Enjoy the thunderstorm!
Updated: Is there any sunshine possible besides the thunderstorm?  The wind is vary large in the night time, and of course, no moon is available this night between 4/11 - 4/21.
4/18: The sun will shine again.  The second part of the sunny days has been starting until 4/23 (4/22?).
Updated: This is the first lati-sunny day in 2007.   The sunny days are good for next 3 days, and then sunshine decreases, and shower/T-shower increases.
Updated2: Because of the lati-sunshine, the temperature goes up to 11 degree C on the same day!
                The situation is not very common in Hong Kong, but it is common in Los Angeles, the USA.

The story of lati-thunderstorm on 4/17 (written on 4/16):

The group of sunshine: Please celebrating the sunny period that represents one of the victory of us...
                                  And see you on 4/18!  Stop sunshine on 4/17 because of the lati-thunderstorm...
The group of cloud-thunderstorm:  Yeah, and owing to the cold front properities, let us play the big game tomorrow, enjoy it,
                                                   and see you than!

(continued #28)

The situation in Los Angeles, the USA (supplmentary): After the storm, the weather is as like as the one in January!
Much worsely, the weather cannot become warmer next few days even though the sun shines.

這幾天的天氣也算是很反覆，星期六（四月十四日）至星期一（四月十六日）的最高氣溫高達二十八、九度，但是今天早上卻低至只有十七度，但是到了下午卻再次高達二十八度。

不過值得一提的是，到了四月最後一個星期的星期二及星期三，氣溫將會低至只有十八度：

這樣的氣溫，真是很容易使人生病。

Oh, you have the wrong date: it should be 4/24 and 4/25, not 5/1 and 5/2.
However, it is very easily to confuse.

Continued from #26 and discuss of #27:

4/19: The sun shines hugely, and the different of the temperature is 7 degree C.
4/20: There is partly to mostly sunny day, and the different of the temperature is 6 degree C.
4/23: If the shortly-sunny-partly-cloudy situation is available, then the weather on the same day is known as lati-thunderstorm-tude-sunshine (tude means and).
4/24 afterward: unlike the situation between 4/17 and 4/18, assume the sunny period cannot go after the lati-thunderstorm.

Everything in the story states that the group of sunshine plays very poor in the long term game.

20/4預測：

．預計於明天（四月二十一日）至下星期一（四月二十三日）間中會有驟雨，之後三天繼續有雨，而且預計於下星期二（四月二十四日）會有雷暴
．下星期四（四月二十六日）預計的最低溫度是十九度，應該會是入夏前最後一次低於二十度了

Some points are also valid in #28.  However, because the weather forcast changes when the real weather changes, some points may be false.

The weather in next few days:
There is/ will be thunderstorm on 4/24: I agree because as I know, there is rainstorm days between 4/23 - 4/25 (break down sunshine on 4/24 - 4/25!! ), the thunder appears on 4/24 is valid.  However, the thunderstorm is not easily checked even by computer, there may or may not be possible to have one on 4/24.  All right, no matter what, I beleive that thunderstorm appears in the lati-rainstorm day is possible.

4/26 - 4/27: HKO assumes no next sunny period because there is not enough condition to have one (expecially on 4/26 which there is up to 55% chance to have shower/T-shower).
The shortly-sunny case cannot come because there is no real meaning in the real weather situation.  Compare with 4/18, changing from rainny to sunny is possible because the sun shines on that day.  It is valid because of high air ridge.  Do not forget the lati-sunshine on 4/18/07.
